Cartridge Valves - Pressure Control

Relief Valves	Used to limit the pressure in a circuit.
Pressure Reducing / Relieving Valves	Used where pressure requirements are less than maximum system pressure. Incorporates a reverse relief function for over-pressure protection.
Direct Operated Pressure Reducing Valves	Used where pressure requirements are less than maximum system pressure.

Relief Valves

Used to limit the pressure in a circuit, these valves are typically adjustable and are available in cavity sizes offering flows from 8 G.P.M. through 40 G.P.M.

Pilot Operated

Description:
Pilot operated relief valves offer quiet operation on systems utilizing fixed displacement pumps.

Direct Operated

Description:
These direct operated valves offer quick response for over-pressure protection on hydraulic circuits.

Pressure Reducing / Relieving Valves

Description:
Pressure reducing/relieving valves are typically applied in a separate leg of the system where pressure requirements are less than the maximum system pressure. They also incorporate a reverse relief function for over-pressure protection.
