4.0Mpa DN50 DIN Standard Ball Valve
Description:
ZHONGYA Floating ball valves mainly apply to the industries of nature gas, oil products, chemical industry, metallurgy, city construction, medicine, environment, foods, etc. As on /off control units. Its body is made of casting or forging; The ball is floating, the ball moves (floats) downstream to maintain close contact with downstream seat to form a reliable seal under the medium pressure when closes. The seat special design has the wearing complementary structure to ensure safe reliable sealing and long stable operation of this series of ball valve. It has the merits of sealing reliability, long life cycle usage and easy operations.
