Pilot Operated Solenoid Valves

Pilot Operated Solenoid Valves are distinguished by their simple, sturdy design. The sealing element is a diaphragm for application pressures up to 20 bar or a piston for pressures up to 450 bar. Valves like this always need a pressure difference to be able to open and close. The minimum required pressure differential for this is stated as the minimum pressure in the technical data sheet. In this case, the actuator only has a pilot function, through which the main sealing element, diaphragm or piston, is relieved. The medium pressure and/or the existing pressure difference lifts the main seal up.

Force Pilot Operated Solenoid Valves

Force Pilot Operated Valves operate from 0 bar, are supplied with smaller solenoids for higher pressures and larger nominal sizes. The actuator opens a pilot orifice and then lifts the sealing element from its seat directly or supported by the delta p of the operating pressure. The special feature of force pilot operated valves is that the actuator in the pressure range can open and close the valve without using the operating pressure. In the case of pressure differences, usually when opening the valve, the collective energy is used.

Type 43 Solenoid Valve

Function: 2/2-Way Valve Connection: G 1/4 - G 2
Body: Brass or Stainless Steel Pressure Range: 0 - 16 bar

Direct Acting Solenoid Valves

Direct Action Solenoid Valves of this type switch the sealing element directly via the magnetic system. They operate from 0 bar up to the maximum operating pressure. In this case the seal usually needs to be lifted against the effective operating pressure from the seat simply by the actuator. A closing spring keeps the valve closed, supported by the pressure of the medium. The function depends on the size of the seat, the effective operating pressure and magnetic power.
