BVSPM33-160 RELIEF VALVE M33X2 | WANDFLUH

FUNCTION
When the set operating pressure is reached, the main spool opens and connects the protected line with the return line to the tank. These pressure relief valves consist of a main-and a pilot operation system integrated into the cartridge. The pilot operation is a direct operated pressure relief valve which acts on the main system. The helical spring of the pilot operation can be easily set to the desired operating pressure. Pilot operated pressure relief valves can be very sensitively adjusted and are suitable for large oil flows and high pressure. The very limited play of the hardened spool results in a limited oil leakage.
APPLICATION
For limiting the operating pressure in hydraulic systems by releasing the oil from the protected oil line P (1) to the outlet/tank return line T (2). The screw-in cartridge is very suitable for mounting in control blocks. Cavity tools are available for hire or sale for machining aluminium or steel. See register 2.13. Attention: Should therefore not be utilized anymore in applications with periodically changing direction of flow.
