    GTL-D373H Hard Seal Wafer Butterfly Valve

     

    GTL-D373H Hard Seal Wafer Butterfly Valve is metal seated triple offset structure, GTL-D373H Hard Seal Wafer Butterfly Valve is metal to metal sealing which provides bubble-tight shutoff which results in no leakage performance.Friction-free stroking is available throughout the cycle which allows the operation with low torque and extends the butterfly valve life. GTL-D373H Hard Seal Wafer Butterfly Valve has no cavities between the sealing elements due to which clogging is eliminated which results in low maintenance and in turn extends the triple eccentric butterfly valve life.

    Characteristics:

    1. The valve adopts three eccentric sealing structure, seat and butterfly plate almost no wear, with a tighter seal function.

    2. The sealing ring is made of stainless steel, with the dual advantages of metal hard seal and elastic seal, both at low temperature and high temperature, have excellent sealing performance, with corrosion resistance, long service life and other characteristics.

    3. Disc sealing surface using surfacing welding cobalt carbide, sealing surface wear resistance, long service life.

    4. Large size butterfly plate adopts quilted frame structure, high strength, large flow area, small flow resistance.

    5. The driving device can be multi-station (rotating 90° or 180°) installation, easy to use.
