Description
Pilot-operated check valves lock a cylinder in any rest position. They are intended for direct mounting in the cylinder.
Advantages
1. Pilot-operated check function and pipe-rupture protection in one valve
2. Optimized hydraulic pilot stage gives gentle opening
3. Leak-free valve seats; hardened, ground and lapped
4. Load pressure acts in the closing direction
