Pre-installation Of KHB, KHM High Pressure Hydraulic Ball Valves

KHB High Pressure Ball Valve

Install the non-turn washer (no. 1) on the stem collar and re-place the O-rings (no. 2 and 5) (using a suitable tool) on the stem and the fitting on both sides, but make sure Do not stretch and keep it as original as possible. (For example: when the O-ring passes through the threaded tap or the four-sided groove of the stem, please use a suitable tool, or use a layer of film to prevent the O-ring from being scratched.) The support ring ((no. 3) is placed on the stem Above the O-ring ((no. 2), that is, away from the pressure-bearing end. In order to prevent the valve stem from being damaged during the installation process of the valve body, it is necessary to ensure that the supporting ring is completely installed in the groove.

KHM High Pressure Ball Valve

Install the thrust washer (no. 1) on the stem collar and re-place the O-rings (no.s 2 and 5) (using a suitable tool) on the stem and the joint on both sides, but make sure Do not stretch and keep it as original as possible. (For example: when the O-ring passes through the threaded tap or the four-sided groove of the stem, please use a suitable tool, or use a layer of film to prevent the O-ring from being scratched.) The support ring (no. 3) is placed on the stem Above the O-ring (no. 2), that is, away from the pressure-bearing end. In order to prevent the valve stem from being damaged during the installation process of the valve body, it is necessary to ensure that the supporting ring is completely installed in the groove. Using a round tool (no sharp edges), gently place the spare O-rings on the joints on both sides, but make sure not to stretch and keep them as original as possible. In a short time, (probably 30-60 seconds), the spare O-ring will return to its previous shape and size, push the spare O-ring onto the threads, and install (no. 5)
