Counterbalance valve - Free Patents Online

The counterbalance valve is considered a pressure valve, but in reality, it controls the speed of an actuator. Without going into too much detail, these valves ensure a cylinder will only move as rapidly as pump flow is dictating, regardless of load-induced pressure or intensification.

fig. 1. The load induces a pressure (Pc) in the cylinder. The overcentre valve is closed. In this way the load keeps its position (Fig, 1). As the valve is set to a certain pressure (Pt), once the load induced pressure nears this setting, the valve starts to open, lowering the load (the valve, in this way, acts like a pressure relief valve).

This unit is a direct acting, screw in cartridge style, poppet type, adjustable, pilot assisted, hydraulic counterbalance valve with free reverse, hydraulic dampening and spring-chamber connected to tank.
