Pressure control seat valve

Design:
Steel body, nitrided. Sealing nut galvanized. All functional components hardened and ground. For sequence valve 6918-3 and 6918-12, the oil is supplied via conduits drilled in the clamping device.
The following valves are required for combining several sequence valves:
6918-3 inlet valve
6918-4 series valve
6918-5 end-of-line valve
The oil is supplied via a threaded connection.

Application:
The pressure sequence valve is used in cases where another consumer is connected to the circuit after a set pressure has been reached. If several sequence valves are employed in the circuit, please note that the pressure in this circuit always adjusts to the last pressure stage.
For this type, the switching pressure remains largely constant, regardless of the outflow pressure on the outlet side (cylinder side).

Note:
During disassembly of the pressure control valve, first loosen SW 24 then SW 22. Installation is carried out in reverse order with the specified tightening torque. Increasing the preload of the compression spring by turning the slotted screw results in a greater pressure difference between P and A. The fastening bolts are not supplied as standard.
