Mutual Weld Type Metal Hard Sealing Butterfly Valve With Handle Operated Color Customer Requied




Company intrduction to on the basis of foregn advanced technology, the precision of the three eccentric multi-level metal hard seal structure,  is widely used in medium temperature<425℃ of the metallurgy, electric power, petrochemical, and to the drinage and municipal construction and other industrial pipeline, adjust the flow and load flow. Valve seat and disc sealing surface are made of different hardness and stainless steel, with good corrosion resistance, long service life, the vavle is a two-way sealing function, the conforms to the national GB/T 13927 vavle pressure test standards.

This butterfly vavle is suitable on system such as petroleum, chemical industry, foodstuff, medicine, papemaking, water and electricity, shipping, plumbing, the smelting and sources of energy etc the pipe route. Can regard on gas, liquid, semifluid as well as solid powder pipes and power lines and the container of many kinds of corrosiveness and non-corrosiveness adjusts and dams a river the equipment use. Especially extensively being in high layer of building fire protection system reaches other to show in the pipes and power lines system of valve of vavle switch state.

The disc of the wafer type butterfly valve is installed in the diameter direction of the pipe. In the cylindrical passage of the butterfly valve body, the disc-shaped disc rotates around the axis, and the rotation angle is between 0°-90°, which can play the role of flow regulation. When the disc rotates to 90°, the valve reaches the maximum. Opening degree.

1. The vavle uses three eccentric sealing structure, the vavle seat and disc almost no wear, with the more closely the sealing function.

2. Sealing ring selection of stainless steel production, with a metal hard sealing and flxible sealing double advantages, both in the case of low temperature and high temperature, have excellent sealing perfomance, with corrosion resistance, long life and so on.

3. The disc sealing surface using cobalt based alloy welding, sealing surface wear resistance, long service life.

4. Lrage format disc using lattice structure, high strebgth, large flow area, flow resistance is small.

5. The vavle has a two-way sealing function, the installation is not restricted by the direction of the media, nor by the impact of spatical position, can be installed in any direction.

6. The driving device can be multi station(rotating 90 degrees or 180 degrees) to install, easy to use.
