Flow-control pressure relief valve MDPRR-08 series

Product catalog summary

Specifications

Operating Pressure: 350 BAR
Flow: 23 L/min
Internal Leakage: 82 ml/min max at operating pressure
Temperature Range: -40°C to +120°C (-40°F to +250°F)
Cavity: 08-3
Fluids: Mineral-based fluids with viscosities of 7.4 to 420 cSt

Features

Hardened, precision ground parts for durability
Industry common cavity
Compact size
Adjustment may be locked in place
Adjustment will not screw out of the valve body

Operation

The MDPRR-08 allows bi-directional flow between ports ① and ② with the spring chamber ③ vented. When the preset pressure at ① is reached, the spool throttles to regulate pressure at ① by restricting flow at ②, relieving pressure from ① to ③.

Performance Curve

The performance curve illustrates the relationship between pressure drop and flow rate, indicating how the valve performs under different conditions.

Application Areas

Transmission, engine, and powertrain control
Building and road construction equipment
Agricultural and garden machinery
Forestry and resource management equipment
Waste disposal equipment
Other professional mobile and industrial applications

Installation Dimensions

Details on installation dimensions and torque specifications are provided for proper setup.

Order Type
