Needle valve MFR-08

Product catalog summary

Technical Specifications

Operating Pressure: 250 BAR
Flow Rate: 0.4-7.5 L/min
Flow Tolerances: 0.2 to 1.8 L/min settings ±15%, 1.9 to 7.5 L/min settings ±10%
Temperature Range: -30°C to +120°C (-22°F to +250°F)
Cavity: 08-2
Fluids: Mineral-based fluids with viscosities of 7.4 to 420 cSt

Product Features

Hardened, precision ground parts for durability
Industry common cavity
Compact size
Adjustment may be locked in place
Adjustment will not screw out of the valve body

Operation

The valve maintains a constant flow rate out of port ② regardless of load pressure changes downstream. The fixed control orifice is preset to customer specifications. The valve responds to load changes when the pressure differential across the control orifice exceeds 5.5 bar, maintaining accurate flow from 7.6 to 240 bar. Reverse flow from port ② to ① is non-compensated.

Performance Curve

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

Installation Dimensions

Order Type: MFR-08 with options for seal kits (Buna N or Viton), body material (6061-T6 aluminum or steel), and body porting (SAE 6T, SAE 8T, G3/8, NPT3/8).

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
