Pilot-operated relief valve MRPCC series

pistonlow-noisecartridge

Specifications · Operating Pressure:350BAR · Flow:45L/min · Response Time - Typical:10ms · Internal Leakage:30ml/min.max.at 70bar · Temperature:-40°C to +120°(-40°F to+250°F) · Cavity:T-162A · Fluids:Mineral-based fluids with viscosities of 7.4 to 420 cSt. Features · Main stage orifice is protected by a stainless steel screen. · Back pressure on the tank port (port 2) is directly additive to the valve setting at a 1:1 ratio. · Will accept maximum pressure at port 2; suitable for use in cross port relief circuits. If used in cross port relief circuits, consider spool leakage. Operation Pilot-operated, balanced-piston relief cartridges are normally closed pressure regulating Valve. When the pressure at the inlet (port 1) reaches the valve setting, the valve starts to open to tank (port 2), throttling flow to regulate the pressure. These Valves are accurate, have low pressure rise vs. flow, they are smooth and quiet, and are moderately fast.
