2 way Semi direct acting solenoid valve

2/2 Semi-direct operated solenoid valves refer to combination the properties of direct and indirect valves. the membrane is lifted not only by the plunger, but also by the pressure differential. When the coil is energized, the plunger moves uprightly, few fluid pass through the valve, membrane opens by the action of inlet and outlet pressure. Vice-versa,when the coil is de-energized,the plunger moves down to shut off the fluid. Under pressure differential and spring force, the valve close completely. This combination results in a valve that operates from zero bar, and can control relatively large flow rates, but need a more powerful coil to control than indirect solenoid valve.
