Controlling Hydraulic Shock with an Electrohydraulic Valve 932405

Hydraulic shock, the banging sound or jumping hoses that occur when a hydraulic valve is used to start, stop, or change a hydraulic actuator's direction or speed, can be eliminated with a new electronic valve.
Parker Hannifin's DigiValve® contains an onboard microcomputer that controls the time needed to change an actuator's direction and speed, thereby eliminating shock problems. The DigiValve can replace two or three existing valves in a typical hydraulic system, including a directional control valve and one or two flow control valves. The DigiValve uses the same voltage level signals as a solenoid-operated directional control valve to change direction, and onboard speed controls to replace manual adjustments of the flow control valves.
