Pressure reducing/relieving valve from Sun Hydraulics
Direct-acting, pressure reducing valves reduce a high primary pressure at the inlet (port 2) to a constant reduced pressure at port 1. These valves incorporate a damped construction for stable operation allowing the use of high reduced pressure. This valve is open in the transition from reducing to relieving. It provides good pressure control and dynamic response.
Note: Data may vary by configuration. See CONFIGURATION section.
