Micro Precision
Hydraulic relief valve block is usually made of high-strength metal, and the internal precision machining of the oil channel connecting the various components. The core component is the relief valve, which is commonly direct-acting and pilot-operated, responsible for opening or closing the relief channel according to pressure changes.
When the system pressure does not reach the set value, the relief valve is closed and the oil flows to the actuator; once the pressure is too high, the relief valve opens and part of the oil flows back to the tank, thereby maintaining the system pressure stable.
Adaptable to various hydraulic systems, any product can be customized according to customer needs.
