Product Name and Model: Flanged Butterfly Valve

Product Usage: 

As a component used to realize the on-off and flow control of pipeline systems, flanged butterfly valves have been widely used in many fields such as petroleum, chemical, metallurgy, and hydropower.

The valve body and the valve seat of the triple eccentric metal hard sealing butterfly valve are connected members, and the sealing surface layer of the valve seat is welded with the temperature resistant and corrosion resistant alloy material. The multi-layer soft stack sealing ring is fixed on the valve plate. Compared with the traditional butterfly valve, the butterfly valve has high temperature resistance, is light in operation, and has no friction in opening and closing. When closing, the seal is compensated with the increase of the torque of the transmission mechanism, and the butterfly valve is improved. The sealing performance and the advantage of prolonging the service life are suitable for industries with high temperature resistance, high pressure, corrosion resistance and wear resistance. The structure type can be divided into single eccentricity / double eccentricity / triple eccentricity.

Structural features

1. The design is novel and reasonable, the structure is unique, the weight is light, the operation is convenient, and the opening and closing is fast;

2. Hard-sealed telescopic butterfly valve can not only adjust and intercept, but also compensate for the thermal expansion and contraction caused by the temperature difference of the pipeline. It can also provide convenience for installation and replacement of valves.

3. The sealing part can be adjusted and replaced, and the sealing performance is reliable.
