Flow-control relief valve MDRBC series

Product catalog summary

Specifications

Operating Pressure: 350 BAR
Flow: 28 L/min
Internal Leakage: 30 ml/min max at nominal setting
Temperature Range: -40°C to +120°C (-40°F to +250°F)
Cavity: T-11A
Fluids: Mineral-based fluids with viscosities of 7.4 to 420 cSt

Features

Pressure at port 3 is directly additive to the valve setting, making it unsuitable as a work port. Consider a 4-port version if needed.
Direct-acting design ensures low internal leakage and low pilot flow loss.

Operation

Direct-acting, 3-way directional cartridges (port 1 blocked, port 2 to 3 open) are used in moderate flow circuits. They can operate independently or actuate larger pilot-operated directional or logic cartridges. The valve shifts when the pressure differential between port 1 and port 3 exceeds the setting.

Performance Curve

The performance curve illustrates the relationship between pressure drop and flow rate, indicating the minimum setting and various pressure levels.

Installation Dimensions

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

Order Type

Adjustment: Screw Adjust (L)
Pressure Range: Various options from 25-4500 psi with preset values
Seal-Kits: Buna N (N) or Viton (V)
Body Material: 6061-T6 aluminum (207 Bar) or steel (350 Bar)
Body Porting: Options include SAE 6T, SAE 8T, G3/8, NPT3/8, and others

Application Area

Transmission, engine, and powertrain control
Building and road construction equipment
Agricultural and garden machinery
Forestry and resource management equipment

Because of this, port 3 may not be usable as a work port in circuit. If this is a consideration, the 4 port version of this valve may be a solution ·由于采用了直动式的设计，这些阀具备了低内部泄漏以及低先导流量损失的特性 Because using direct-acting design,these valve hare low internal leakage and low pilot flow loss features.
