Pilot-operated relief valve MRPIC series

Product catalog summary

Specifications

Operating Pressure: 350 BAR
Flow: 380 L/min
Response Time - Typical: 10 ms
Internal Leakage: 66.5 ml/min max at 70 bar
Temperature Range: -40°C to +120°C (-40°F to +250°F)
Cavity: T-16A
Fluids: Mineral-based fluids with viscosities of 7.4 to 420 cSt

Features

Main stage orifice is protected by a 150-micron 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. Consider spool leakage if used in such circuits.

Operation

Pilot-operated, balanced-piston relief cartridges are normally closed pressure regulating valves. When the pressure at the inlet (port 1) reaches the valve setting, the valve opens to the tank (port 2), throttling flow to regulate the pressure. These valves are accurate, have low pressure rise vs. flow, are smooth and quiet, and have a moderate response speed.

Installation Dimensions

Details on installation dimensions and torque specifications are provided, including specific measurements and maximum torque values.

Order Type

Adjustment: Screw Adjust (L)
Pressure Range: Various options from 25-6000 psi with preset values
