FULL DATA SHEET

This valve is used to regulate the pressure of the pump's forked fluid line.

It maintains the pressure which is persistent and lower than the fluid origin not to affect the main fluid line.

Oil flow is permitted from port 2 to port 1 up to the pressure value set in port 1.

When the pressure value is reached, spool throttles the passage port 2 and port 1 to keep the pressure in port 1 constant.

The passage in port 3 is used as a drain with steady connection to the discharge.

There is no pressure relief from port 1 to port 3, when pressure in the line port 1 exceeds the set value.
