DG3V-7-20 Pilot operated directional valve
DG5V-7-30 Solenoid controlled pilot operated directional valve
DG*V-7 valves are used primarily for controlling the starting, stopping and direction of fluid flow. Two series of valves, DG5V solenoid controlled, pilot operated and DG3V pilot operated models are available with a wide selection of spools. These include meter-in and meter-out spools and a regeneration type that can obviate extra valves essential in traditional circuit arrangements. All spools have been designed to provide good low shock, fast response characteristics which can be enhanced by optional stroke and/or pilot choke adjustments. Models include spring offset, spring centered and detented versions.
DG5S4-04-60/70 Pilot operated directional valve
DG5S4-04 models are two-stage directional valves having an integrally mounted DG4V-3(S)-60 pilot valve. These valves are generally used to control the direction of flow in a hydraulic circuit. This in turn would control the movement of a work cylinder or the rotation of a fluid motor.
