Pilot-operated relief valve MRAH101-S series

pistoncartridge

Specifications · Operating Pressure:380BAR · Flow:113L/min · Internal Leakage:5ml/min.max.to 80% of norminal setting · Temperature:-40°C to +120°(-40°F to+250°F) · Cavity:10-2 · Fluids:Mineral-based fluids with viscosities of 7.4 to 420 cSt. Features · Hardened,precision ground parts for durability. · Not suitable for use in load holding applications due to spool leakage. · Will accept maximum pressure at port 2;suitable for use in cross port relief circuits. · Industry common cavity. 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.
