Control valves modulate flow in response to a control signal to maintain a process variable. Selection involves sizing for the required Cv, choosing the trim and body style, defining the flow characteristic, and specifying the actuator and positioner. Leakage class per FCI 70-2 should be specified for the duty.
Q: What is a control valve used for?
A: Control valves regulate process flow, pressure, level, or temperature by modulating the flow path in response to a controller signal.
Q: How are control valve leakage classes defined?
A: Leakage is typically classified per FCI 70-2 / IEC 60534-4, ranging from Class I (no test) to Class VI (tight shutoff, bubble-tight for soft seats).
Guidance reflects general engineering practice for control valves; confirm against the project specification and applicable standards before procurement.
