Sun Hydraulics Pilot-to-Open Check Valve

Sun Hydraulics pilot-to-open check valves are non-modulating, on-off devices used for holding a load or actuator in position. They can be directly integrated into your actuator or applied using manifolds with many mounting options.

These valves offer protection against hose breaks and positively lock pressurized loads. They are available in non-vented (3-port) and vented (3- and 4-port) versions. They are also directly interchangeable with counterbalance cartridges – with the same number of ports, same cavities and same flow path for a given frame size.
