Features and Application:
Three eccentric Butterfly Valve series is the newly-developed long-life and energy-saving products. The sealing is metalto metal, which couldbe changed to be Seal Ring to metal,stainless steel plate and composite
graphite to metal. Under the working condition of hightemperature 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
