Direct-operated relief valve MRV3-8 series

Product catalog summary

Specifications

Operating Pressure: 210 BAR
Flow: 18.9 L/min
Internal Leakage: 3 ml/min max to 80% of nominal setting
Temperature Range: -40°C to +120°C (-40°F to +250°F)
Cavity: T-2106
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
Low leakage design
Fast response to pressure surges

Operation

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

Performance Curve

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

Installation Dimensions

Detailed dimensions and torque specifications are provided for proper installation.
