WESSEL PRESSURE RELIEF VALVE TYP PRV-1DA
Description
The PRV-1DA pressure relief valve is a direct operated, robust valve for small volume flows and high pressure. It can be used as pressure cut-off valve in control blocks. There are three variants available: Manually adjusted, hydraulically and electrically proportional operated.
Characteristics
- Cartridge valve
- High pressure resistance up to 420 bar
- Electric proportional, hydraulically or manually adjustable

Example of Application
Together with a hydraulically actuated 2/2 way valve, a pressure limiting function with a flat characteristic curve can be established. P opens to PT as soon as the set pressure is exceeded. The return pressure has no influence on the pressure at P, thus sequence controls or priority circuits can be established.
Anwendungen
- Pressure cut off
- Pump pressure relief p
- Pilot valve for pressure relief
