Product details

On the characteristics of hard-sealing butterfly valve
1, the use of three eccentric butterfly valve can be called the top process valve, the design of the valve for high temperature, high pressure, fire-resistant foam sealing ideal sealing valve.
2, due to the use of welding structure, so that the valve and the pipeline plane to achieve a permanent zero leakage.
3, the valve can not be flanged, bringing great convenience and beautiful appearance to the pipe and insulation bandaging.
