Single Seated Globe Valve for Ratings ANSI 150-600

Features General Designed to ensure it represents a cost effective solution to a variety of process control applications, the construction of this range of valve is of a simple form allowing rapid assembly and high interchangeability of trims. Performance: — High flow capacity. — Tight shut-off. — Excellent flow control rangeability. — Low weight. — Streamline flow passages to improve capacity. Design Flexibility: — Inherent Modified Equal Percentage trim, with options for equal percentage and linear from characterised positioner. — Clamped guide and seat allows quick change for modification/service. — High interchangeability of trim components and soft parts. Design Integrity: — Optimised using computer aided analysis. — Designed to ASME B16.34 — High integrity precision cast components. Quality Manufacturing: — Rigorously tested to ensure specified performance on site. — Quality Assurance systems certified to ISO 9001 — NACE MR-01-75 certification.

Guide to Trim Options Available

ABB Series14 -10/02

Figure 1. Contoured Trim

Standard Duty For standard duty applications there is the option of Contoured trim (Figure 1) or Cage Guided trim (Figures 2 and 3)

Trim Design Options: Contoured & Cage Guided trims have Full and reduced trim capacity.

Characteristics Available: Inherent Modified Equal Percentage (Equal Percentage & Linear available with characterised positioner)

Plug Options: Unbalanced Contoured Trim.

Figure 2. High Friction Cage Trim illustrated with Balanced Plug

Unbalanced Cage Guided (1” to 4” Valves) or Balanced Metal/Metal Cage Guided (1.1/2” to 4” valves) with Resilient or Graphite piston rings. Soft seats are available for bubble tight shut off.

Direction of Flow: Recommended flow under for both liquids and gas of Contoured trims. Flow over the plug for liquids & flow under for gases of Cage Guided trims.

Severe Duty: The High Friction (HF) trims are suitable for high pressure drop applications to prevent the onset of cavitation and reduce the noise levels generated as the result of both gas/vapour and liquid flows.

General Selection information The information detailed is intended to act as a general guide, to assist in the selection of a Series 14 Valve

Trim Cv Calculation A full set of procedures for calculating the Cv with various fluids is detailed in the Sizing and Selection Manual. Please contact the nearest Sales Office for your copy.

Body Selection The valve body must be capable of supporting the selected trim without producing excessive velocities. The following tables can be used as a guide for determining the maximum recommended body velocities for both liquid and gas/ vapour applications.

Liquid Service The velocities detailed in Table 3. below reflect the normal inlet and outlet maximum velocities recommended to eliminate body erosion and prevent trim instability. Other factors may reduce the following figures further. Refer to Sizing and Selection Manual for further details. Table 3. Recommended maximum inlet and Outlet Velocities Liquid Service

Gas/Vapour Service These velocities avoid problems of vibration and body erosion. Where noise levels are a consideration velocities should be restricted to the relevant Mach numbers. Table 4. Recommended maximum inlet and Outlet Velocities Gas/Vapour Service

Trim Inherent Rangeability The inherent rangeability of a valve trim is dependant on a number of factors including size and style. The values detailed in Table 5. provide a general guideline to the maximum achievable values. Table 5. Maximum Inherent Rangeability

Inherent Flow Characteristic

Optional Flow Characteristics*

The inherent flow characteristic of a control valve is the relationship between the flow and the valve travel at constant pressure drop.

The optional flow characteristic is the relationship between the flow and the control signal at constant pressure drop. *Available only with positioner

Maximum Leakage Rates Leakage rates are normally measured in accordance with the ANSI/FCI 70-2-1976 specification using the class designation. The following Table 6. defines the achievable leakage class for each available plug designs. Table 6. Achievable Leakage Class
