The structure of the Quick Release Valve For IVECO is characterized by the main body, spring, piston rod, piston and other parts. The back pressure capacity is large, the discharge rate is high, the pressure can be relieved quickly, and the operation is simple. The working principle of Quick Release Valve is: when the pipeline pressure reaches the set value, the spring begins to compress, and the piston moves upward. When the runner in the piston is opened, the internal pressure in the pipeline is rapidly reduced, so as to achieve the purpose of pressure relief. When the pressure inside the pipeline is reduced to the set pressure, the spring begins to restore its original state, the piston falls, the spool is closed, and the pipeline returns to normal working state.
