Solenoid Valve with Differential Pressure (Indirect Acting Solenoid Valve)

Indirect acting solenoid valves operate on the servo assistance principle, relying on a minimum differential pressure between the inlet and outlet to function. When the solenoid is energized, it opens the pilot seat, releasing pressure from the main closure device. The pressure differential across the valve helps lift the closure device into the open position. Once the pilot seat closes, bleed orifices allow pressure to build on the closure device, securely sealing it against the valve seat. These valves are ideal for applications with consistent flow conditions and sufficient differential pressure, offering reliable performance for fluid and gas systems.
