Product Features

Hardened, precision ground parts for enhanced durability
Compact design
Adjustment can be locked in place
Fast response to pressure changes

Operation

The valve prevents flow from port ① to ② until the set crack pressure at port ① is reached. The poppet then unseats, allowing flow from ① to ②, thereby protecting the circuit from over-pressurization.

Performance Curve

The performance curve illustrates the relationship between pressure drop and flow rate, with pressure drop measured in psi (bar) and flow rate in gpm (lpm).

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
