Product description

Notes

These valves must be set according to the application.
SAE screw-in bores of cartridge valves from different manufacturers may have slight differences, e.g. in the depth and diameter of the valve seat, despite having the same screw-in thread. It is therefore essential to compare all relevant dimensions using the technical data of the screw-in bore when replacing.

Description

These valves reduce a high primary pressure at port 2, to a lower, regulated pressure at port 1.
The pressure relief function enables the oil to flow out via port 3, to the tank if there is overpressure at port 1.
The valves ensure stable operation even at high differential pressures.
