BUTTERFLY VALVE
Wafer type Butterfly Valve
The structure feature of Concentric Wafer Type Butterfly Valve is that the stem axis, the disc center and the body center are in the same position.
Body:Ductile Iron/Stainless steel/Aluminum alloy
Disc:Ductile Iron/Stainless steel/Duplex stainless steel/aluminum bronze
Seat:EPDM/NBR/PTFE/VITON
Flange type Butterfly Valve
Concentric Flanged butterfly valve is used for pipeline water supply and drainage, gas pipeline regulated flow and closed the medium.
Body:Ductile Iron/Stainless steel
Disc:Ductile Iron/Stainless steel/Duplex stainless steel/aluminum bronze
Seat:EPDM/NBR/PTFE/VITON
Lug type Butterfly Valve
The disc of concentric lug type butterfly valve is installed in the diameter direction of the pipeline.
Body:Ductile Iron/Stainless steel
Disc:Ductile Iron/Stainless steel/Duplex stainless steel/aluminum bronze
Seat:EPDM/NBR/PTFE/VITON
U type Butterfly Valve
The U-shaped butterfly valve adopts a top-mounted structure, which reduces the connecting bolts of the valve body itself under high-pressure and large-diameter conditions, enhances the reliability of the valve and overcomes the impact of the system’s own weight on the normal operation of the valve.
Body:Ductile Iron/Stainless steel
Disc:Ductile Iron/Stainless steel/Duplex stainless steel/aluminum bronze
Seat:EPDM/NBR/PTFE/VITON
Grooved Butterfly Valve
Grooved butterfly valve is used for conveying all kinds of corrosive and non-corrosive fluid media during pipeline transmit system
Body:Ductile iron/WCB/SS.,etc.
Disc:SS/DSS/Copper Alloy
Seat:EPDM/NBR/PTFE/VITON
Fully Teflon Butterfly Valve
The butterfly plate of the fluorine-lined butterfly valve is installed in the diameter direction of the pipe.
Body:Ductile Iron/Stainless steel/Carbon Steel
Disc:Stainless steel/Carbon Steel+PTFE/PFA
Seat:PTFE/PFA
Hard seal wafer eccectric Butterfly Valve
The hard-sealed butterfly valve is a regulating valve with a simple structure and can also be used for switching control of high-pressure pipeline media.
Body:WCB/SS.,etc.
Disc:SS/CS
Seat:SS/CS
Hard seal flange Butterfly Valve
The hard-sealed butterfly valve is a regulating valve with a simple structure and can also be used for switching control of high-pressure pipeline media.
Body:WCB/SS.,etc.
Disc:SS/CS
Seat:SS/CS
Double eccectric Butterfly Valve
The effect of double eccentricity makes the disc can quickly away from the seat once valve is opened, greatly reducing the unnecessary excessive squeeze and scraping of the disc and the seat, reducing the open resistance distance, reducing the wear and tear, improving the life of the seat.
Body:Ductile iron/WCB/SS.,etc.
Disc:SS/Ductile iron/WCB
Seat:SS/CS
