Operating Principle of Pneumatic Control Valve:

Pneumatic Control Valve works on the principle that energy stored in compressed air is converted into mechanical energy using a Pneumatic Actuator. The actuator takes instructions from the Control System or Valve Positioner to control the valve opening.

The controlled movement helps in controlling the flow rate, pressure control, temperature control, and level control in automatic systems. Owing to their quick action and reliability, Pneumatic Actuated Control Valves find wide application wherever there is the need for Process Control and Flow Control.
