  • Flange Butterfly Valve with Supporting Legs

    Flange Butterfly Valve with Supporting Legs

     Usually when the nominal size of the valve is greater than DN1000, our valves come with support legs, which makes it easier to place the valve in a more stable way. Large diameter butterfly valves are usually used in large diameter pipelines long with you over to control the opening and closing of fluids, such as hydroelectric power stations, hydraulic stations, etc.

     

  • NBR Seat Flange Butterfly Valve

    NBR Seat Flange Butterfly Valve

    NBR has good oil resistance, usually if the medium is oil, we will preferably choose NBR material as the seat of the butterfly valve, of course, his medium temperature should be controlled between -30℃~100℃, and the pressure should not be higher than PN25.

  • Electric Rubber Full Lined Flange Type Butterfly Valve

    Electric Rubber Full Lined Flange Type Butterfly Valve

    The fully rubber-lined butterfly valve is a good addition to the customer’s budget when they cannot afford to use 316L, super duplex steel, and the medium is slightly corrosive and in low-pressure conditions.

  • Concentric Cast Iron Full Lined Butterfly Valve

    Concentric Cast Iron Full Lined Butterfly Valve

     Concentric PTFE Lining Valve also known as fluorine plastic lined corrosion resistant valves, are fluorine plastic molded into the inner wall of the steel or iron valve bearing parts or the outer surface of the valve inner parts. Fluorine plastics here mainly include: PTFE, PFA, FEP and others. FEP lined butterfly, teflon coated butterfly valve and FEP lined butterfly valve are usually used in strong corrosive media.

     

  • Pneumatic Wafer Type Triple Offset Butterfly Valve

    Pneumatic Wafer Type Triple Offset Butterfly Valve

    Wafer type triple offset butterfly valve has the advantage of being resistant to high temperatures, high pressure and corrosion. It is a hard seal butterfly valve, usually suitable for high temperature(≤425℃), and the Maximum pressure can be 63bar. The structure of the wafer type triple eccentric butterfly valve is shorter than the flang triple eccentric butterfly valve, so the price is cheaper.
