Cast steel worm gear eccentric hard sealing ball Industrial Valves is a relatively new type of ball valve type, it has its own unique structure of some advantages, such as switch frictionless, seal is not easy to wear and open-close torque is small. Which can reduce the distribution of the specifications of the actuator. With multi-turn electric actuators, which can realize to adjust the medium and carefully cut off. Widely used in petroleum, chemical industry, urban water supply and drainage and other demanding cutting conditions. Cast steel worm gear hard seal eccentric half ball valve product figure

cast steel worm gear eccentric hard sealing ball Industrial Valves structure characteristics 1, fluid resistance is small, the resistance coefficient with section of equal length. 2, simple structure, small volume, light weight. 3, compact and reliable, ball valve sealing surface material widely used plastic, sealing is good, have been widely used in the vacuum system. 4, easy to operate, open and close quickly, from open to close just rotate it 90 & deg; To facilitate remote control. 5, convenient maintenance, simple structure of ball Industrial Valves, sealing ring, which generally remove replacement is more convenient. 6, in the full open or full close, sphere and valve seat sealing surface and the dielectric isolation, medium through, does not cause the valve sealing surface erosion. 7, wide applicable scope, size from small to several millimeters, big to a few meters, from high vacuum to high pressure can be applied. Spin 90 degrees, in the inlet and outlet should be completely present spherical, thereby cutting flow.
