Model DXV Relief Valves

DXV Cushion Valves are designed to eliminate or minimize shock, surge and overload conditions on hydraulic equipment. They may be used with cylinders of equal displacement or with motors, to provide crossover relief up stoppage. Under standard conditions, when a control valve is in neutral or closed position, the excess pressure created by overload, shock or stress has no possibility of relief through the primary relief valve. A Cushion Valve located between the control valve and the actuator minimizes or eliminates this condition. In a motor application, the need for an anti-cavitation check may be eliminated, since relieved oil is directed into the opposite side of the Cushion Valve. Model DXV, with ball/spring relief valves, has hardened seats for long, trouble-free service. It is available with a PSI check spring which will allow the cushion valve to act as a relief in one direction and permits free-flow at 5 PSI in the opposite direction.
