Cartridge pressure relief valve MPBDB series

Product catalog summary

Specifications

Operating Pressure: 350 BAR
Flow: 40 L/min
Pilot Flow: 0.11 - 0.16 L/min
Temperature Range: -40°C to +120°C (-40°F to +250°F)
Cavity: T-11A
Fluids: Mineral-based fluids with viscosities of 7.4 to 420 cSt

Features

Reverse flow from reduced pressure (port 1) to inlet (port 2) may close the main spool. Consider adding a check valve for reverse free flow.
Pilot-operated valves have flat pressure/flow characteristics, good stability, and low hysteresis.

Operation

Pilot-operated pressure reducing valves adjust high primary pressure at the inlet (port 2) to a constant reduced pressure at port 1, allowing circuits with multiple pressure requirements to operate using a single pump.

Performance Curve

The document includes a performance curve showing pressure drop versus flow, indicating no load pressure drop with the valve fully open.

Installation Dimensions and Order Type
