GSR – Innovative Valve Technology
Solenoid Valves, pilot operated
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.
By use of small solenoids, high pressures at large nominal sizes can be controlled. The mounting of valves up to DN50 is possible in any position. Due to a simple exchange of the coil as well as the seal, the valve can be easily serviced.
Usually, these valves can be used everywhere where the medium can be relieved outdoors or into a pressure less housing. Valves of this type, however, cannot always be used in closed circuits. Please contact your GSR-Team.
Pilot operated valves are used, for example, in:
- Filling systems
- Irrigation systems
- Fountain equipment
- Sanitary equipment
- Water treatment
- Pneumatics
- Mixing systems
- Pipelines
- Drinking water supply
and many other applications in the general machine and equipment construction field.
We indicate a minimum pressure for our valves. The pressure differential is necessary, in order to lift the sealing element reliable or to close. Decreases the pressure differential under the indicated minimum pressure, we cannot guarantee a proper function.
