Trunnion ball valve using the principles of

Trunnion ball valve is guaranteed by the pressure poorly. Flat stack valve to valve flatness and smoothness requirements friction plane quite high, and the requirements for the use of materials Instrument needle valve also have high demands. To solve these problems, flat lamination stack valve using a ceramic substrate under the topsheet other using a high-strength wear-resistant material, in full accordance with the principles of chemical mechanical seal manufacturing and processing, both to ensure a reasonable contact surface, and ensure the minimum coefficient of friction. Trunnion ball valve has emerged cause Valve manifolds quality problems due to prolonged blockage of the pilot hole, the pressure relief valve stem causing the valve stem is stuck adsorption of iron particles and other issues, through the use of market information and feedback, developers have learned Trunnion ball valve actuators Division is currently unsuitable water quality of water use. Thus, the developers turned to the ball and flat stack valves. Now use the ball a little more.
