Supape control sarcina
Load control application tips
3-ported counterbalance valves
These valves are used with an open center on/off directional valve for:
Precise control of overrunning loads
Protection from pump cavitation
Preventing actuator from running ahead of the pump supply and
Providing load holding and hose failure safety
Vented (4-ported) counterbalance valves
These valves are used for:
Precise control of overrunning loads
Regenerative cylinder circuits
Meter-out control and providing load holding and hose failure safety with proportional control valves
Pilot operated check valves
These valves are used:
For position load locking
As an alternative to counterbalance valves where neither the overrunning loads or release speed are factors in the application.
Pilot operated check
