Transport in the gas gas and natural gas pipeline, underground valve and its substitutes used in the past are not sealing, sealing or driving piece of sticking coke tar or other issues, causing the valve can not be opened or closed lax, over the years, these problems have been plaguing users, the valve manufacturer is also difficult to to solve. In recent years, our company signed by the foreign advanced experience, through repeated trial, to launch a new structure of this series valve, fundamentally overcome the shortcomings to the gate, the gas pipeline has the best valve equipment.
And the special structure can make the sealing side sealing seat and the valve does not contact with the media, thus effectively avoid coking of the sealing surface and the valve stem thread.
In the fully open and fully closed, the valve plate, small friction, wear, good sealing performance, long service life.
