1.Wafer metal seal butterfly valve products use

The use of sophisticated J-shaped elastic ring seal and three eccentric multi-layer metal seal structure is widely used in metallurgy, power, petrochemicals, and plumbing and municipal construction and other industrial pipe media temperature ≤ 400 ℃, for regulating flow And breaking the fluid to use.

 

2.Clamp metal seal butterfly valve Features

1, the clamp metal multi-level butterfly valve butterfly valve connection structure is simple, easy installation and removal, light weight. Metal seal butterfly valve with three eccentric seal structure, the valve seat and disc almost no wear, with the more the more tight sealing function.

2, the ring made of stainless steel, with the advantages of both metal seal and flexible seal, both in the case of low temperature and high temperature, have excellent sealing performance, with corrosion resistance, long service life and so on.

3, the butterfly plate sealing surface using welding cobalt-based hard alloy, sealing surface wear-resistant, long service life.

4, Large-format butterfly plate frame structure, high strength, large flow area, small flow resistance.

5, the metal seal butterfly valve has a two-way sealing function, the installation is not subject to restrictions on the flow of media, but also the impact of space location, can be installed in any direction.

6, the drive can be multi-station (rotated 90 ° or 180 °) installation, user-friendly.
