Product name: warfer stainless steal butterfly valve

Key word ; stainless steal butterfly valve

Product type; D373H-16P

First work conditions ;

I can plant the introduction of advanced technology from abroad on the basis of a sophisticated J-shaped elastic ring and three eccentric multi-level metal seal structure, and is widely used in medium temperature of ˇÜ 425 ˇć governance of the electricity, oil and chemicals, as well as water supply and drainage Municipal and industrial pipeline construction for regulating air flow and the use of stop-contained. The valve by three eccentric structure, and the valve seat dish plate sealing surface are different hardness and the production of stainless steel, has excellent corrosion resistance and long service life, the two-way valve sealing function, product line with the state GB/T13927-92 pressure valve Test criteria

 

Second characteristics

.1 ,he valve seal by three eccentric structure, butterfly valve seat and almost no wear plate with the concept of the tight sealing function.
2 ,Valve stainless steel production, a flexible metal seal and seal the dual advantages of both the low temperature and high temperature under all circumstances with excellent sealing properties with corrosion-resistant, long life and other characteristics.
3 the sealing surface of a plate of plate welding cobalt-based alloy, sealing surface wear resistance and long service life.
4 ,the board adopted specifications Butterfly Hang truss structure, high strength, flow area, flow resistance small.
5 ,the valve seal is a two-way function, installation medium flows from the restrictions, but also from the position of space can be installed in any direction.

6 ,can drive the Multi-Position (rotating 180 ˇă or 90 ˇă) to install, easy to use
