direct relief valve

Product description:

Direct acting relief valve is a common hydraulic control element used to control the pressure of the hydraulic system. By adjusting the opening degree of the overflow port, the pressure of the system is kept within the set range.

The working principle of the direct-acting relief valve is: when the system pressure exceeds the set value, the spring of the relief valve is compressed, so that the overflow port is opened, and the excess hydraulic oil flows back to the tank, thereby reducing the system pressure; When the system pressure is lower than the set value, the spring returns to its original state, the overflow port is closed, and the system pressure is restored.

Direct acting relief valve has the advantages of simple structure, high reliability, fast response speed, etc., and is widely used in hydraulic system, such as construction machinery, metallurgical equipment, ships and other fields.
