Pressure reducing/relieving valve from Sun Hydraulics
Ventable, pilot-operated pressure reducing/relieving valves reduce a high primary pressure at the inlet to a constant reduced pressure at port 1, with a full-flow relief function from port 1 to tank (port 3). The vent port (port 4) can be used as a means for remote control by pilot or 2-way valves.
Note: Data may vary by configuration. See CONFIGURATION section.
