2pc Ball Valve

Description of 2pc Ball Valve:
ZECO Ball valve is the same to the ordinary that trim spring with the stem to reach the purpose of open/ close, it is mainly adopted to cut off medium on pipe. It features for simple structure, good sealing capacity, flexibility, small blockage coefficient, easy operation etc. ZECO is the global supplier of 2PC ball valves, which can be divided into 2PC floating ball valves and 2PC trunnion mounted ball valves.
 
Features of 2pc Ball Valve:
1.  As the moving parts of valve, ball, valve stem and handle are an assembly unit. The head of valve stem is shaped a diploid, thus to easily distinguish whether valve is in the “ON” position from handle position. When handle or stem diploid is in parallel with the pipe axis, valves is in “ON” position, when handle or stem diploid is vertical to the pipe axis, valve is in “OFF” position;
2. 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;
3. 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 accumulated in the ball from the static channel between the ball and the stem, or between the stem and valve body;
4. 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.
