The solenoid valve of the disc filter burns out frequently

However, during operation, the two-way three-port valve of the disc filter leaks, allowing water to enter the cylinder and then, through the air pipes, cause the control solenoid valve to burn out, resulting in the disc filter not being able to function properly. What could be the reason? 1. It might be due to high pressure caused by the ultrafiltration unit, which leads to leakage (the outlet pressure of the disc filter is 0.). 22 MPa). 2. It is also caused by poor quality of the cylinder seals. I hope experts can provide an explanation; thank you.
Our factory uses the same process as yours, and the pressure of the water coming out of the disc filter is often higher than 0. 22 MPa; no such problems have occurred over the five years of operation. I think it’s likely due to poor quality of the cylinder seals
There must be a problem with the two-way three-port valve and the cylinder design; the leaking water has nowhere to go and can only flow into the cylinder
