Control valve and shutoff valve datasheet keypoint required & it's meaning

Question

Accepted Answer

Control valve and shutoff valve datasheet key points and their meanings.

Control valve datasheet key points: flow capacity, pressure drop, valve type, actuator type, material, size, Cv value, rangeability.
Shutoff valve datasheet key points: valve type, material, size, pressure rating, leakage class, end connections.
Control valve datasheet key points meaning: Flow capacity - maximum flow rate through the valve, Pressure drop - pressure difference across the valve, Valve type - type of valve (e.g., globe, butterfly), Actuator type - type of actuator (e.g., pneumatic, electric), Material - valve construction material, Size - valve size, Cv value - valve flow coefficient, Rangeability - ratio of maximum to minimum controllable flow rate.
Shutoff valve datasheet key points meaning: Valve type - type of valve (e.g., gate, ball), Material - valve construction material, Size - valve size, Pressure rating - maximum allowable pressure, Leakage class - allowable leakage rate, End connections - type of connections (e.g., flanged, threaded).
