VB400 Four Eccentric High Performance Butterfly Valve Flanged Butterfly Valve

VB400 Four Eccentric High Performance Butterfly Valve (Large circulation capacity, reliable sealing, long life)

VB400 four eccentric high-performance butterfly valve, the sealing surface is eccentric in the horizontal center, the rotation axis has two distances eccentric in the axial and radial direction relative to the flow center, the shape of the short axis of the circular sealing section is a positive circle, which realizes the no friction of the sealing auxiliary during opening and closing and automatic anastomosis and sealing movement. It has the advantages of advanced structure, large circulation capacity, reliable sealing and long life.

1. Adopt four eccentric structure, suitable for ultra-low temperature and high temperature and other complex working conditions, and require strict cutting occasions, small opening moment.
2. The sealing subsection changes from a three-eccentric elliptical structure to a positive circular structure, with greater circulation capacity.
3. The radial offset is reduced, which reduces the unbalanced force of the medium on the valve plate and improves the two-way sealing performance
4. High strength corrosion resistant alloy is overwelded to ensure the reliability of the sealing surface and long service life.
5. Using high strength stainless steel material and integral valve stem structure, bear the allowable pressure difference is large.
