there are floating ball valve and fixed ball valve according to the structure of the sealing mechanism.

ball valves have many advantages. 1. Simple structure, small size and light weight. 2. close and reliable valve sealing surface material widely used plastic, sealing in a vacuum system has also been w

stainless steel ball valve is actuaged by a 90 degree turn for fast on/ off action.

As an example of conventional ball valves, a so-called "union-type ball valve" is known in which a ball is arranged in a cylindrical valve body in such a manner that it can open and close a fluid pass

ball valves are designed to the low light structure and widely used in metallurgy industry in the piping system.

A full port ball valve has an oversized ball so that the hole in the ball is the same size as the pipeline resulting in lower friction loss

ball valves have many types, V port ball valve, trunnion ball valve, cavity filler ball valve,two way ball valves, three way ball valves, and so on.

Due to the ball valve usually use rubber, nylon and ptfe as seat sealing material, as a result its temperature is limited by seat sealing material. The cutoff function of the ball valve is completed b
