Pilot or direct operated backpressure valve in sandwich construction. The backpressure valve, also called pre-loading valve, opens the main spool when the adjusted pressure is reached.
Back pressure valve
Sandwich construction
- pilot operated or direct operated
- pmax = 400 bar
- pN max = 350 bar
- Qmax = 30 l/min
Application
