1. Avoidindustrial high pressure valves working under small opening. If the needle opens slowly or with small opening, the throttle clearance is small and the erosion is serious, properly increase the pitch of the locking mechanism, increase the opening speed and lift, increase the opening, make the throttle clearance larger, erosion weaker, and increase the service life. Life.

2. Avoid industrial high pressure valves working in high-temperature medium, medium temperature has a great impact on the life of the valve. The higher the medium temperature, the shorter the life of the high-pressure valve, and vice versa. Therefore, adding a cooling device at the relief valve can also significantly improve the service life of the valve.


3. Under different working pressures, use the corresponding sealing pressure, select the appropriate sealing specific pressure, use the moment wrench to lock, or realize the automatic control ofindustrial high pressure valves, so as to avoid pin being squeezed with the valve seat without erosion and wear.
