Features and Application:
Three eccentric butterfly valve series is the newly-developed long-life and energy-saving products.The sealing is metal to
metal, which couldbe changed to be seal ring to metal, stainless steel plate and composite graphite to metal. Under the
working condition of high temperature and high pressure, it still has a stable sealing performance. Our company adopts
optimization design and new technology, so that the torque is small, gainning the point of energy-saving, labor-saving and
reliable sealing performance, thus to ensure the high-reliability of corrosion-resistantance, stand fire and wear-resistantance.
This product is widely used in petroleum, natural gas, piped gas and medicine, food industry, industrial environmental
water treatment and shipping industry.
The seal ring of the butterfly plate comes as a soft -hard layers overlapped metal piece and holds the dual advantages of both
metal hard seal and elastic seal and excellent sealing property,whether in a low or high temperature.
With the three -dimensional eccentric structure used ,there is almost no friction between the seat ring and the butterfly plate,
featuring such a sealing function as:the further closed ,the tighter.
The sealing face of the body uses stainless steel and cobalt -based carbide alloy-welding so that the side face is wearable
and lasts longer.
Unique structure ,flexible ,laboursaving and convenient operation ,without being affected with either a high or low medium
pressure,reliable sealing performance, long life of use .
