In order to extend the service life of ultra high pressure valve, but also consider its working conditions.

1. To avoid the valve in the small opening work, if the needle valve open lift small open or slow, to work in a small opening, the throttle gap is small, severe erosion, increasing the locking mechanism of the pitch, increase the opening speed and lift, the work of opening increases, envoys flow gap, erosion weakened, can be improved by the use of life.

2. To avoid the valve in the high temperature medium, the temperature of the valve on the life of the media, the higher the temperature of the medium, the shorter the life of the valve, and vice versa. Therefore, the pressure relief valve in the cooling device, but also can significantly improve the service life of the valve.

3. Under different working pressure, and the corresponding proper sealing pressure than the pressure seal, use torque wrench for locking the valve or automatic control, thus avoiding the valve needle is not in erosion and extrusion and damage the valve seat.

4. Regularly filter high pressure medium and clean filter, add liquid to apply filter to filter. Frequent use, should be appropriate to shorten the cycle. Cleaning the tank regularly, and the replacement of the new media, according to the actual situation of the equipment can shorten the cleaning and changing period.

5. Install or replace the needle to make proper cleaning of the. In order to avoid accelerated wear debris into the needle.
