Product catalog summary

Technical Specifications

Operating Pressure: 207 BAR
Flow Rate: 37.5 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: 10-2
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
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

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

Order Type

Seal Kits: Buna N or Viton
Body Material: 6061-T6 aluminum (207Bar) or steel (350Bar)
Body Porting: SAE 6T, SAE 8T, G1/2, NPT1/2, and other options available
Pressure Range: Various ranges with preset options
Adjustment: Screw, handwheel, or nonadjustable
