Control Valve Positioners

S Bharadwaj Reddy
The reason why a pneumatic control valve’s stem position corresponds linearly to the amount of air pressure applied to the actuator is because mechanical springs tend to follow Hooke’s Law,...

Pneumatic Valve Positioner Working Principle

S Bharadwaj Reddy
The Pneumatic Valve Positioner is an instrument working on force balance principle to position the Control Valve stem in accordance to a pneumatic signal received from a controller or manual...

Control Valves Theory

S Bharadwaj Reddy
The flow regulation  in a valve  is accomplished  by the varying  resistance as the valve  is stroked, i.e. its effective cross sectional area is changed. As the fluid moves from...

Control Valve Positioner Working Principle

S Bharadwaj Reddy
A Control Valve Positioner is a device used to increase or decrease the air load pressure driving the actuator until the valve’s stem reaches a “POSITION” balanced to the output SIGNAL from...
