Gear Operated Ball Valve

Description of Gear Operated Ball Valve:
Large size ball valve if adopt manual operation will reduce the efficiency of personnel, even if many people help may also be because of the large size of excessive torque can't open or close the valve, so the large-diameter ball valve ZECO basically adopts the gear operation, the gear can drive way through the gear structure greatly reduce open or close the valve torque, could have been three operations may be only one operation can be completed. In addition, ZECO can manufacture turbo heads with waterproof grade or full spray coating according to customers' requirements.
Features of Gear Operated Ball Valve:
1.ZECO gear operated ball valve has a stem anti - fly out design. It is different of lever operated ball valve.In ball valve need to change the packing or for corresponding maintenance, need to clear the packing gland, in order to prevent the discharged gland, the stem will be hurt by pressure within the lumen and top fly to maintenance personnel, ZECO in a setting on the stem for stem convex in gland place, no matter how much lumen pressure stem fly out burst damage will not happen;
2.The connecting parts of the valve body and the left body of ZECO ball valve are cushion seals. In order to prevent the sealing leakage caused by fire, high temperature or vibration, ZECO designed the connection between the valve body and the left body as metal and metal contact, forming a flange to ensure no external leakage;
3.ZECO gear operated ball valve is designed with anti-static device. When the ball valve in the process of opening or closing, non-metallic materials on the surface of the ball and seal friction generating electrostatic, such as static medium is derived and the line is combustible materials will be very serious incidents, so ZECO design on the stem and ball anti-static device, composed of spring and the metal ball, which can be produced by electrostatic export the valve body;
4.ZECO gear operated ball valve is designed to be fire protection. In case of fire, non-metallic materials such as packing and seat or some materials with low ignition point will be seriously burnt down and lead to serious leakage and expansion of fire situation. The fire-proof structure of ZECO Valve company can ensure that after these non-metallic materials are burned down, the leakage can be prevented through the metal seal of the ball and valve body to ensure the normal operation of the pipeline.
