Pressure reducing valve from Sun Hydraulics
Pilot-operated, pressure reducing valves reduce a high primary pressure at the inlet (port 2) to a constant reduced pressure at port 1, allowing circuits with multiple pressure requirements to be operated using a single pump.
Note: Data may vary by configuration. See CONFIGURATION section.
