Butterfly valve is use disc type opening and closing member to open、close and adjust medium flow by 90°reciprocating rotary.
Butterfly valve is not merely with simple structure, small volume, lightweight, small driving torque, easy to handle, quick operating, but has a good flow control function and sealing characteristic. It is one of the fastest growing variety in the past decades.
Butterfly valves are used in a wide range of applications. The varieties and quantities used are continue to expanding. And developing to high temperature, high pressure, large diameter, high sealing, long operating life, excellent control characteristics, and multifunction.
Its reliability and other performance indicators have reached a high level.
Agent brand: GS Butterfly Valve, Germany
Features: The disc and the valve body adopt the conical oblique cutting seal. In addition, the rotating shaft deviates the center of the flow channel, the sealing surface deviates from the rotation shaft is create a three-eccentric structure, Therefore, the sealing property is good. The butterfly sealing ring is laminated with the stainless steel sheet and the graphite sheet. It can prevent the sealing surface from being engaged effectively.
>except the moment of opening and closing, the butterfly plate and the valve seat have no friction and the torque is small.
>The valve body sealing use build-up welding with hard alloy, which has good abrasive resistance and long service life.
> Lightweight design for light and flexible operation.
>less pressure loss and the small flow resistance.
>All valves feature a standard blow-proof valve shaft construction for safer use.
