Armaş “PRPS” model pressure reducing/sustaining hydraulic control valve reduces valve downstream pressure to desired value by sustaining upstream pressure. Two pilot valves exist on valve. Pilot valve on upstream side is the pressure sustaining pilot valve and sustains upstream pressure. Other pilot valve is pressure reducing pilot valve and keeps downstream pressure constant by reducing it to desired value. It controls upstream and downstream pressure continuously and keeps them within constant values.
Valve size same as main line or one size smaller. Maximum flow speed for continuous operation 5.5 m/sec (18 ft/sec)
