504001 YF Overflow Valve

Purpose and characteristics 

The YF Overflow Valve functions to prevent overload of the hydraulic system and maintain its constant pressure. The remote pressure regulator valve is a small direct-acting overflow valve, which may be connected with the remote control port of overflow valve to realize remote pressure regulation in the set range of main overflow valve pressure. When the remote control port of overflow valve is communicated with the return oil circuit via a direction change valve, the oil circuit off-load may be achieved. Connecting the remote control port of overflow valve via a reversing valve and multiple remote pressure regulator valves may realize multi-level control over the high-low pressure; replacement of pressure adjusting spring of the overflow valve may change its pressure regulation range.
