- When the medium go through the valve, the pressure in middle cavity would pull out the stem. In order to prevent the occasion from happening, a convexity is designed. At the same time, a lubricator device has been added, so even if the fire damage would happen to damage the o-ring. the lubricator device would inject sealing oil to prevent medium from leaking:
- When operating the valve, the friction between the ball and the nonmetal seat, like PITE or etc. will produce electrostatic charge that can be accumulated on the ball. To prevent static spark, an anti-static device is placed on the valves to derive the electric charge accumu lated in the ball from the static channel between the bal and the stem, or between the stem and valve body;
- In order to prevent the mal-operation of the valve, the open/close position can be equipped with lock device, especially when they are used outdoor or process forbidden the malfunction-
