Modular Stack Valves - Load Holding
Load holding valves are available in pilot operated check valves or counterbalance valves for applications requiring locking and holding the load in any position.
C03MSV-P* and C05MSV-P* – Pilot Operated Check Valves (Cast Iron)
Pilot Operated Check Valves
These valves allow free flow from the directional control valve work port to the load and blocks flow in the opposite direction. Flow is allowed from the load to the directional control valve work port when 30% of the load induced pressure is sensed in the opposing directional control valve work port.
- NFPA D03 and D05 mounting patterns
- Pressures to 5000 PSI and Flow to 32 GPM
- Guided spool and poppet-seat lock the load in place
P03MSV-C* and P05MSV-C* – Counterbalance Valves (Aluminum)
Pilot Operated Counterbalance Valves
The P0*MSV-C counterbalance valves with pilot assist are designed to control an overrunning load or hold a load in position by maintaining a back pressure on the outlet of the cylinder. An integral check valve allows for free flow in the reverse direction.
- 0-5 Drop per minute leakage
- Pressures to 3000 PSI and 30 GPM
- NFPA D03 and D05 mounting patterns
