Solenoid Valves, force pilot operated

› Product range

› 3D graphics control type

Force pilot operated valves operate from 0 bar and can be installed where directly acting valves are used. However, they are supplied with smaller solenoids for higher pressures and larger nominal sizes if used instead of this application range.

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.

Valves of this type can be used in a wide range of applications, for example, vacuum or high pressure applications.

These valves offer an operating security of the highest order as well as a large range of extras.

Force pilot operated solenoid valves can be used reliably both in the low pressure range and also for higher pressures.  

Force pilot operated valves are used, for example, in:

• Filling systems
• Steam boiler construction
• Liquid gas systems
• Hot water applications
• Heating circuits
• Power plant technology
• Petrochemicals
• Pump equipment
• Tank systems
• Water treatment
• Pipeline construction
• Drinking water supplies

and many other applications in the general machine and equipment construction field.

Special: No differential pressure is necessary in order to work.

Force pilot operated valves open and close independently of pressure and seal only in the direction of the arrow. The preferable mounting is with upright actuator. Please contact us before installing in a different position or into a riser.

In order to avoid water hammer effects an adjustable close muting is supplied as standard for sizes from G5/4 and DN32.
