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
