control valve actuator bench set

Actuator Bench-set | Basic Principles of Control Valves ...
Bench set is a very important parameter for a control valve because it establishes the seating force (seat load) of the plug against the seat when the valve is fully closed. Proper seating pressure is critical for tight shut-off, which carries safety implications in some process services.
