The valve with a metal seal generally has a longer life than the valve with an elastic seal, but it is difficult to achieve a complete seal. Metal seals can adapt to higher operating temperatures, while elastic seals have temperature-limited defects.

If the ball valve is required to be used for flow control, the main thing is to correctly select the size and type of valve. The structural principle of the ball valve is especially suitable for the production of large diameter valves.

Structural characteristics

① Eccentric unique design makes the sealing surface frictionless transmission, prolonging the service life of the valve.

② Elastic seal produced by torque.

③ The clever wedge design makes the valve have the automatic sealing function of the closer and tighter, and the sealing surface has compensatory and zero leakage.

④ Small size, light weight, light operation, easy to install.

⑤ Pneumatic and electric devices can be configured according to user requirements to meet the needs of remote control and program control.
