Direct-operated relief valve MRV-08M series

Product catalog summary

Technical Specifications

Operating Pressure: 315 BAR
Flow: 22.7 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: M201.5T (refer to page J-18)
Fluids: Mineral-based fluids with viscosities of 7.4 to 420 cSt

Product Features

Hardened, precision ground parts for enhanced durability
Compact design
Adjustment can be locked in place
Fast response to pressure surges

Operation

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

Performance Curve

The document includes a performance curve illustrating the relationship between pressure drop and flow rate.

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 are provided, including torque specifications for different components.

Order Type

Seal-Kits: N = Buna N, V = Viton
Body Material: A = 6061-T6 aluminum (rated at 207 Bar), S = Steel (rated at 350 Bar)
Body Porting: Options include SAE 6T, SAE 8T, G1/2, NPT1/2, with other porting available
