Troubleshooting Reasons for the Failure of the 315-ton Hydraulic Press Cartridge Valve to Seal and Maintain Pressure

Troubleshooting Reasons for the Failure of the 315-ton Hydraulic Press Cartridge Valve to Seal and Maintain Pressure:

1. 1.The internal casting quality of the 315-ton hydraulic valve body or integrated block (such as air holes, cracks, shrinkage, etc.) is poor, leading to leaks and leaks at the integrated block connection surface.

2. 2.Seal failure of the O-ring on the outer cylindrical surface of the 315-ton hydraulic valve sleeve.

3. 3.The conical surface coordination between the valve core and the valve sleeve in the four-column hydraulic press is not tight, causing internal leakage between chambers A and B.

4. 4.When using an electromagnetic valve as a pilot valve for pressure maintenance in the cartridge-type hydraulic control one-way valve, the inherent internal leakage of the slide valve-type electromagnetic valve cannot effectively seal and maintain pressure.
