Design:

Steel housing, nitrided. Sealing nut galvanized. All functional components hardened and ground. Balls out of roller bearing steel.

Application:

The pressure sequence valve is used where another hydraulic system or another consumer should be activated after achieving a specified pressure. If a curcuit is designed with several sequence valves, it must be observed that the pressure in this circuit is always adhisted in the last respective pressure stage. The switching pressure for this type, irrespective of the pressure on the output side (consumer side) remains largely constant.

Note:

For disassembly of the pressure valve please release first SW (AF) 24, then SW 22. For assembly please use reverse sequence and observe max. seating torque. The pressure difference between P and A depends on the preload of the adjustment spring.
