Differential relief valve MDRV-08 series

Product catalog summary

Specifications

Operating Pressure: 250 BAR
Flow Rate: 30 L/min
Internal Leakage: Maximum of 5 drops/min to 80% of nominal setting
Temperature Range: -40°C to +120°C (-40°F to +250°F)
Cavity: 08-2 (refer to page J-8)
Fluids: Mineral-based fluids with viscosities from 7.4 to 420 cSt

Features

Durable, hardened, precision-ground parts
Industry-standard cavity
Compact design
Lockable adjustment
Low leakage design
Fast response to pressure changes

Operation

The valve prevents flow from port ② to port ① until the set crack pressure at port ② is reached. Once achieved, the poppet unseats, allowing flow from ② to ①, thus protecting the circuit from over-pressurization.

Performance Curve

The performance curve illustrates the relationship between pressure drop and flow rate, with specific values provided for different flow rates and pressure drops.

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 and Ordering Information

Seal Kits: N (Buna N), V (Viton)
Body Material: A (6061-T6 aluminum, 207 Bar), S (Steel, 350 Bar)
Body Porting: Options include SAE 6T, SAE 8T, NPT 1/2, G1/2, with other porting available
