I. D73H type hard sealed Butterfly product overview : Our company introduces to advanced foreign technology on the basis of , uses sophisticated J elasticity to seal enclosing and three partial multi-level metal hard seal structure , is widely used in medium temperature ≤ is 425 degrees centigrade of metallurgy, electric power, petrochemical, and gives draining off water and urban construction etc. on the industry pipeline , make the flow of regulating and break fluid use in year. This valve adopts three partial structure , seat and disc Board seal adopt different hardness and stainless steel , has good corrosion resistance , long life , valve this two-way sealed function , products meet national GB/T13927-92 valve pressure test standard . Second, D73H type hard sealed butterfly's valve features : 1, A valve adopts three partial sealed structure , valve seat and butterfly's Board have not almost been worn and torn , concept with the more urgent sealed function. 2Selection of stainless steel, seal and , have metal hard sealing and double advantage with elastic sealing , in low temperature and high temperature situations are , has an excellent sealing performance , with corrosion-resistant , long service life etc. 3, Disc Board seal surface adopts the surfacing cobalt base hard alloy , seal wear-resisting , long service life . 4, Butterfly's Board of the heavy specification adopts hang's shelf structure, the intensity high , , flow area , is it hinder little to shed. 5, Valve this have two-way sealed function , installations not subject to the restrictions of the media flow , free of the space position too , can install in any direction. 6You can drive, multi-station ( rotating 90 ° or 180 °) installation , user friendly.
