Valve Positioners | Basic Principles of Control Valves and ...

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, where the amount of spring motion ((x)) is directly proportional to applied force ((F = kx)).A pneumatic actuator applies force as a function of air pressure and piston/diaphragm area ((F = PA ...

Common Control Valve Problems | Basic Principles of ...

Thus, the effects of friction on a pneumatic control valve actuator may be quantified by subjecting the valve to small reversals in applied actuator pressure and measuring the resulting stem position. The largest increment of actuator pressure reversal resulting in zero stem motion represents the total amount of friction within the valve mechanism.

How It Works: Actuators | Schlumberger

At a basic level, an actuator is a control mechanism that is operated by an energy source. This energy—hydraulic pressure, pneumatic pressure, or electric current—moves the internal mechanical parts of the actuator. Actuators can be designed to fail open (in the case of actuator failure, the valve will stay open) or fail close (in the case ...
