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 document includes a performance curve showing the relationship between pressure drop and flow rate.

Installation Dimensions

Detailed dimensions and torque specifications for installation are provided.

Order Type

Seal-Kits: N = Buna N, V = Viton
Body Material: A = 6061-T6 aluminum (207 Bar), S = Steel (350 Bar)
Body Porting: Options include SAE 6T, SAE 8T, G1/2, NPT1/2, and others
Pressure Range: Various ranges from 50-3300 psi with preset options
Adjustment: Options include Screw Adjust, Handwheel Adjust, Hidden Adjustment
