Product Features

Fast response to pressure surges
Hardened poppet and seat for long life
Adjustment can be locked in place
Industry common cavity
Compact size
Adjustment prevents spring from going solid

Operation

The valve is a pilot-operated, balanced-piston relief cartridge that is normally closed. It regulates pressure by opening to the tank when the inlet pressure reaches the valve setting. It offers high accuracy, low pressure rise versus flow, smooth operation, low noise, and moderate response speed.

Performance Curve

The performance curve illustrates the pressure drop versus flow rate, indicating the valve's efficiency across different flow rates.

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
