Product Description

D373H Gear wafer end butterfly valve is metal seated triple offset structure,D373H Gear wafer end 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. D373H Gear wafer end 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.

D373H Gear wafer end butterfly valve specification:
● Material: Cast Iron, Ductile iron, Carbon steel. Stainless Steel and others
● Actuator Type: Lever type
● Operating Pressure: 10-40 bar,150LB-300LB
● Medium Temperature: -10 to 180 ℃ for rubber seat, -40 to 450℃ for metal seat.
● Size Range: 2″ to 8″
● Suitable Medium: Water, Oil, Air, Gas, etc.

D373H Gear wafer end butterfly valve product features:
1. D373H Gear wafer end butterfly valve adopts three eccentric sealing structure, seat and disc almost no wear, with tighter sealing function;
2. Butterfly valve 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. Butterfly valve sealing surface using surfacing cobalt-based hard alloy, sealing surface wear resistance, long service life;
4. Large size disc adopts quilted frame structure, high strength, large flow area, small flow resistance;
5. D373H Gear wafer end butterfly valve with two-way sealing function, installation is not restricted by the flow of media, is not affected by the spatial position, can be installed in any direction;
6. The driving device can be multi-station (rotating 90° or 180°) installation, easy to use.
