Direct-operated relief valve MRV-SDV40 series

Product catalog summary

Specifications

Operating Pressure: 240 BAR
Flow: 150 L/min
Internal Leakage: Maximum of 5 ml/min at 80% of nominal setting
Temperature Range: -40°C to +120°C (-40°F to +250°F)
Cavity: RV-SDV40
Fluids: Mineral-based fluids with viscosities of 7.4 to 420 cSt

Features

Hardened, precision ground parts for durability
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 port 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 pressure drop versus flow rate, indicating how the valve performs under different flow conditions.

Installation Dimensions

Details on the installation dimensions and order types are provided, including options for seal kits, body material, and body porting.

Order Type

Seal Kits: N (Buna N), V (Viton)
Body Material: A (6061-T6 aluminum, 207 Bar), S (Steel, 350 Bar)
Body Porting: SAE 6T, SAE 8T, G1/2, NPT1/2, other options available
Pressure Range: Various options with preset pressures

Application Area

Transmission, engine, and powertrain control
Building and road construction equipment
