Pressure reducing 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.
Note: Data may vary by configuration. See CONFIGURATION section.
