Wafer Type Ductile Iron Butterfly Valve For Industrial Pipelines
Butterfly Valve Uses
The valve system to absorb, digest foreign technology, using three-dimensional eccentric multi-levelmetal seal structure, applicable to medium temperature = 550 ℃ metallurgy,electric power, petrochemical,as well as to the drainage pipe for regulating fluid flow and cut off the best device.
Feature
1,buttertly plate sealforthe hard and softlayering pieces of metal with a metal seal and flexible seal the dual advantage of both low and high tamperature
cases,both with excellent sealing perormance.
2, using hree-dimansional eccentric sructure, valve seat and buterly plate almost no fiction, with the more closed more tight sealing function.
3, valve sealing surface, using welding stainless steel, cobalt-based alloy, sealing surface wear reslstance and long service life.
4, The struclure is unique, the operaion nimble,reduces elor,conveniently,the medium pressure high,the lowinuence, the sealing properly not to be unreliable,the service life is long.The usual double eccentric butterfly valve, as b (deviate from the pipe center) and a (deviate from the sealing surace of the centerline) as shown in the alm of reducing valve seat and seal between the friction of approximately 15* travel.HPV adds a unique eccentric angle , slope ofthe cone not only overcome he valve open and clase the sealand the seatall contacts between the fricion.
