What Are Pilot-Operated Valves?
Pilot-operated valves are valves that control the main flow using a small air pilot.
The operating principle of these valves is that the pilot valve opens with the inflow of air, allowing the passage for the main flow to open, and ultimately, the main valve opens. They are utilized in various industries, including industrial machinery, construction machinery, and automobiles. Their characteristic feature is the ability to control large fluid flows with a small air pilot and operate at high speed.
Their structure mainly consists of a pilot air valve and a main valve. The pilot air valve controls the flow rate and pressure of the pilot air, while the main valve controls the flow rate and pressure of the main flow.
