Direct Acting, Spool Type, SAE-8 Cartridge – DR08-01

Pressure Reducing valve DR08-01

The DR08 is a direct-acting, spring-loaded, spool type pressure reducing valve.

Its function is to maintain a constant pressure on the consumer. Indeed, in the normal position, the connection of the pressure port 2 is to the consumer port 1. The pressure building at the consumer acts on the face of the control spool and moves it upwards against the set spring force. Therefore, restriction of the flow at port 2 is enough to satisfy the consumer’s demand without increasing the pressure.

In addition, the valve has a pressure relieving function: If the pressure across consumer port 1 rises above the control pressure due to an external force, the control piston is pushed further against the spring and relieves the consumer to tank port 3.
