The Basic Design of Control Valves
- Aug 30, 2018 -

The general design of any control valve comprises three primary parts

  • Body

  • Actuator

  • Positioner

Control nozzles can be opened or closed via electrical, hydraulic, or pneumatic actuators. The positioners are used to open and close the actuator via pneumatic or electric signals. Depending on the type of control valve, these three components can have different designs.
