However, in the practical application, there are still some common faults that need to be solved in time. Here are some common faults and solutions for double pilot check valve for crane.
1. Valve leakage
Valve leakage is usually caused by the wear of valve seat and valve core. To solve this problem, the valve core and valve seat should be replaced in time.
2. Unable to open or close
This fault may be caused by the damage of spring or sealing ring. Therefore, the damaged parts should be replaced in time.
3. Slow response
The slow response of double pilot check valve may be caused by the increase of resistance in the valve core movement. In this case, the valve core and the valve seat should be cleaned or replaced.
4. Abnormal noise
Abnormal noise is usually caused by the wear of internal parts or poor lubrication. The internal parts should be inspected and replaced if necessary, and the lubrication system should be improved.
5. Low efficiency
If the efficiency of double pilot check valve is low, it may be caused by the reduced flow rate or pressure of the hydraulic system. Therefore, the hydraulic system should be checked and adjusted in time.
In order to ensure the normal operation of double pilot check valve for crane, it is necessary to carry out regular maintenance and inspection, timely solve the above common faults, and replace the damaged parts in time.
