PRODUCT RANGE Series JOS-E and JLTJOS-E are the standard conventional relief valve designs for applications when the discharge is to the atmosphere or to a low pressure exhaust system designed to contain the process fluid. Series JBS-E and JLTJBS-E pressure relief valves incorporate a bellows which is balanced to minimize the effects of variable back pressure on valve set pressure and can also handle applications involving high built-up back pressure. For liquid service applications, Series JLTJOS-E and JLTJBS-E provide stable operating performance using our industry-recognized patented liquid trim design, which allows the valve to achieve full lift at 10% overpressure without valve chatter. Series JOS-H-E are open bonnet pressure relief valves intended for ASME Code Section VIII steam service applications and are furnished with a regular lifting lever as standard. Series JBSBP-E and JLTJBSBP-E are balanced bellows valves with a supplementary back pressure balancing piston. Series JOS-E-B and JBS-E-B are BlockBody pressure relief valves that provide a cost-effective alternative to multiple high pressure smaller orifice valves. Series JOS-E-RL and JBS-E-RL are restricted lift valves with a physical stop reducing the rated capacity to meet application requirements. J-Series capacities are certified by the National Board of Boiler and Pressure Vessel Inspectors. Their castings and forgings are procured to ASME/ASTM material specifications and are available in a number of material combinations such as Monel®, Hastelloy® and stainless steel in addition to a number of special material combinations such as titanium, duplex stainless steel and Inconel®, which are available on application. Dimensions of flanges conform to current ASME Standards. All steel raised face flanges are spiral concentric serrated finish with 45 to 55 grooves per inch and a finish between 125 Ra and 200 Ra. Other flange facings, such as ring type joint, are available on request.

CROSBY J-SERIES DIRECT SPRING PRESSURE RELIEF VALVES SEAT DESIGN

FIGURE 1

Series JOS-E and JBS-E relief valves are available with flat metal-to-metal or soft seats. Their two-piece disc holder/disc insert construction provides thermal balancing assuring maximum seat tightness and meets the requirements of API Standard 527, ‘Seat tightness of pressure relief valves’. Where system operating conditions permit, soft or elastomer O-ring seat construction is available as an option. This two-seat design (Figure 1) has a metal-to-metal seat located downstream of the soft seat. The O-ring is the primary seal. The flat metal-to-metal seat controls the compression of the O-ring and also serves as a secondary seal should the O-ring be damaged. Elastomeric O-ring soft seat valves are tightness tested at 95% of set pressure, exceeding the requirements of API Standard 527. Standard O-ring materials include FKM, Buna-N, EPR, TFE, silicone rubber and Kalrez® (see page 16). Other soft seat materials, their pressure and temperature limits are available on application.

DUAL CERTIFICATION Series JLT pressure relief valves for liquid service were developed using our unique patented trim design. This contoured liquid trim design (Figure 2), with over 25 years of successful field experience, was patented prior to the issuance of ASME Code Section VIII requirements that became mandatory in 1985. The JLT trim offers a significant increase in capacity at 10% overpressure and, in many cases, results in selection of a smaller valve with an associated reduction in inlet and discharge piping costs. The JLT design is also capacity certified for gas and vapor service and can be applied in two-phase flow applications. The JLT design is a logical choice where the process fluid may be a liquid or gas depending on the overpressure condition.

FIGURE 2

BELLOWS CONVERTIBILITY The flanged, spring operated pressure relief valve is designed and manufactured as a conventional valve and a balanced bellows valve. The conversion from conventional Series JOS-E or JLTJOS-E in sizes 1" D 2" through 8" T2 10" requires only the addition of a bellows assembly and bellows tail-piece gasket. No other parts are necessary.

BELLOWS AND TOP FLANGE All standard JBS-E and JLTJBS-E valves feature a standard bellows and top flange (Figure 3) manufactured from Inconel® alloy 625, which is a fatigue-resistant material and provides improved corrosion resistance compared to 316L stainless steel. It is highly resistant to pitting, crevice corrosion and inter-granular attack. The standard bellows assembly threads onto the disc holder with a bellows tailpiece and gasket. A welded bellows attachment is available as an option.

CROSBY J-SERIES DIRECT SPRING PRESSURE RELIEF VALVES EASE OF MAINTENANCE AND COMPONENT INTERCHANGEABILITY

FIGURE 4

The JOS-E and JBS-E’s disc insert retention, disc holder and nozzle ring have been engineered to ensure ease of maintenance, minimize spare parts and provide a high degree of component part interchangeability (Figure 4). The disc insert is held securely in place with a compressible retention clip. A ‘universal’ disc holder allows simple and cost effective conversions from conventional to balanced bellows design and enables cost-effective bellows replacement. The nozzle ring encloses the adjustment slot at the bottom of the ring giving a rugged, durable design.

CAP, LIFTING LEVER AND SPINDLE INTERCHANGEABILITY All JOS-E and JBS-E relief valves (except restricted height caps) use a threaded spindle and drilled and tapped bonnet which permits easy cap or lifting lever conversions, with maximum standardization and interchangeability of parts. In addition, standard cap and lifting lever designs can be used with in-line test devices.

CROSBY J-SERIES DIRECT SPRING PRESSURE RELIEF VALVES SERIES JLTJOS-E/JLTJBS-E LIQUID TRIM PRESSURE RELIEF VALVES Series JLTJOS-E and JLTJBS-E pressure relief valves for liquid service were developed using our unique patented contoured trim design (Figure 5). The JLT trim offers a significant increase in capacity at 10% overpressure and in many cases, results in selection of a smaller valve with an associated reduction in inlet and discharge piping costs. It provides smooth and stable valve operation on liquid service applications.

OPERATION When system pressure reaches the specified set pressure, a small stream of fluid begins to flow from the valve. Valve disc lift at this pressure is minimal. As the system pressure increases into the range of 3% to 5% overpressure, the valve then opens with a pop type lift to the full lift position. At 10% overpressure, the JLT valve will have attained full lift and be flowing an amount equal or greater than the rated capacity (Figure 6). As the system pressure begins to drop, flow through the valve decreases until the valve reseats with a clean positive closing action. The JLT design is also capacity certified for gas and vapor service and can be applied in two-phase flow applications.

CROSBY J-SERIES DIRECT SPRING PRESSURE RELIEF VALVES SERIES JOS-H-E OPEN BONNET PRESSURE RELIEF VALVES Series JOS-H-E relief valves (Figure 8) are intended for ASME Code Section VIII steam service applications and are furnished with a regular lifting lever as standard. The standard chrome steel spring in the JOS-H-E open bonnet design is exposed for atmospheric cooling. Optional accessories include a test rod as well as a weather hood. Materials of construction are identical to the standard closed bonnet JOS-E design. The JOS-H-E has a maximum temperature rating of 800°F [427°C] using WCB/WCC. carbon steel body and bonnet and chrome steel spring. Series JOS-H-E (and JOS-E) relief valves for steam service at set pressures above 450 psig use a 316L stainless steel disc holder with disc bushing and threaded 17-4 ph stainless steel disc insert (see Figure 7).

CROSBY J-SERIES DIRECT SPRING PRESSURE RELIEF VALVES VALVES Crosby JOS-E and JLT-JOS-E pressure relief valves are available in a restricted lift version. All J Series variations including JBS and all service medias may be supplied in a restricted lift version. The purpose of a restricted lift valve is to more closely match the required capacity of the protected vessel or pipe with the actual and rated capacities of the relief valve providing overpressure protection. Restricted lift (RL) versions of the J series may be built by a certified Emerson manufacturing facility or by an ASME certified Assembler with the required certification Specific to the RL version (National Board certificates 01045 and 01382).

OPERATION The restricted lift design adds a stainless steel washer to the top of the disc holder. The washer restricts the lift of the disc holder by creating a physical stop with the guide at a lower lift value than the disc holder and guide alone. When system pressure reaches the specified set pressure, the valve begins to go into lift. As the system pressure increases the valve will exhibit a pop type lift at either set pressure or 3-5% overpressure depending on the trim type. At 10% overpressure the valve will have attained its restricted full lift. As the system pressure begins to drop, flow through the valve decreases until the valve reseats identically to any other trim configuration. The JOS-E-RL/JLTJOS-E-RL design is capacity certified on gas, liquid, and steam and can be used on any JOS-E/JLTJOS-E trim variant.

CROSBY J-SERIES DIRECT SPRING PRESSURE RELIEF VALVES SERIES JBSBP-E AND JLTJBSBP-E BALANCED BELLOWS VALVES WITH SUPPLEMENTARY BACK PRESSURE BALANCING PISTON Series JBSBP-E and JLTJBSBP-E are a modification to the standard bellows pressure relief valves which have been designed and tested in collaboration with engineers of one of the world’s leading petroleum companies. This adaptation provides additional assurance of safe performance in the event of bellows failure on installations with discharge manifold systems where constant or variable back pressures are present. With the standard bellows pressure relief valve, if the bellows is broken or ruptured, the valve will perform in the manner of a standard valve without bellows. Introduction of the supplementary back pressure balancing piston assures full performance characteristics of the valve until necessary replacement of the bellows can be made, affording double protection. Unless compensated for, the effects of back pressure may cause (1) a change in the opening pressure (2) a decrease in valve capacity and (3) valve performance to become unstable at higher back pressure. Use of the bellows valve with supplementary balancing piston maintains the balancing effect even after bellows failure enabling the valve to function in essentially the same manner as with the bellows intact. However, the bonnet of the valve must be vented to ensure proper valve functioning. The vent also serves as a ‘tell-tale’ in case of a ruptured or broken bellows. Design The auxiliary balancing piston is incorporated in the basic bellows valve, modified to include the piston (5B) and the cylinder (17) which is part of the disc holder. The guiding clearances are held to a minimum and, in addition, grooves in the piston form a labyrinth seal to reduce flow between the piston and cylinder. In the event of a bellows failure, the leakage of fluid to atmosphere is kept to a minimum.

CROSBY J-SERIES DIRECT SPRING PRESSURE RELIEF VALVES CAPS AND LIFTING LEVERS Caps Styles JOS-E/JBS-E/JLT pressure relief valves are furnished with a closed bonnet and screwed cap over the adjusting bolt. The following types of top construction are available, except where indicated otherwise: Screwed cap (Type J standard) - where no lifting lever is required. Bolted cap (Type L) - where no lifting lever is required. Available to special order. Lifting levers ASME Code Section VIII requires that a lifting lever must be supplied with the valve when the service is: (1) air (2) water at the valve inlet that exceeds 140°F (60°C), excluding overpressure or relief events or (3) steam. Regular (Type C) - for steam and air service where the valve cap is not required to be tight on the discharge side and where conditions dictate a requirement for periodic testing. Regular lifting levers may be furnished with a supplementary gagging device on special order (designated as Type T). Packed (Type D) - For services where tightness on the discharge side is necessary and where conditions dictate a requirement for periodic testing. Also recommended for hot water services. ASME Code Section VIII requirements for lifting levers: The omission of the lifting lever is permitted under Code Case 2203. However, Emerson requires that orders for relief valves intended for steam, air or water over 140°F without lifting levers must indicate that the valves are specified in accordance with Code Case 2203. The buyer is responsible for obtaining jurisdictional approval for use of this Code Case. Test rods Types K, E or M - valves with screwed caps, packed lifting levers or bolted caps can be fitted to accommodate test rods which will hold the valve closed when the equipment on which they are installed is hydrostatically tested. Type J screwed cap changes to Type K with test rod. Type D packed lifting lever changes to Type E with test rod. Type L bolted cap changes to Type M with test rod. Height restricted applications For applications where there are height restrictions, cap Types A, B, G and H are available. CAUTION Test rods should never be tightened more than finger-tight as over-tightening may damage internal parts. Also, a test rod should never be kept on the valve during operation of the equipment. During normal operation the test rod is replaced with a cap plug and gasket to maintain tightness on the discharge side.

CROSBY J-SERIES DIRECT SPRING PRESSURE RELIEF VALVES SERIES JOS-E-B/JBS-E-B PRODUCT OVERVIEW Series JOS-E-B/JBS-E-B BlockBody valves provide greater capacity and can be set at pressures and temperatures significantly higher than the traditional design cast steel API Standard 526 relief valves. One single BlockBody installation has satisfied the capacity of twelve smaller valves. The BlockBody design also adds significantly to the scope of materials that can be provided in accordance with ASME Code Section VIII by adding a wide array of wrought materials. Utilizing the BlockBody design, higher material integrity is offered which can minimize non-destructive examination (NDE) requirements. BlockBody relief valves can be designed to unconventional sizes which can be an advantage when retrofitting to existing systems. Pressure relief valve outlet sizes can be increased beyond API standards to eliminate outlet piping reducers and mitigate built-up back pressure in the downstream piping.

FEATURES • Geometrically designed body and bonnet eliminates the need for multiple, smaller orifice cast steel API Standard 526 pressure relief valves. • Provides significant weight reduction when compared to multiple smaller orifice PRVs. • Significantly reduces inlet and discharge piping costs. • Reduced downtime and maintenance. • Fewer spare parts required. • Specific inlet/outlet flange configurations and combinations available with unique center-toface dimensions to meet existing systems. • Forged body standard construction increases choice of materials available for harsh or corrosive service applications. • Suitable for back pressure applications considerably beyond CI 300 service. • Reliable and field proven design.
