Application
Overcentre valves give static and dynamic control of loads by regulating flow into and out of hydraulic actuators. The Overcentre valve will stop the load from running away in the event of a hose burst. If open centre directional control valves are used, they will allow the thermal expansion relief of the hydraulic fluid. These valves provide excellent hose burst protection.
The following valves are Sun-fit valves that fit into Sun Cavities T-11A and T-2A
The following list contains valves from Tucson that are not Sun-fit valves, but perform the same functions
