Flange three eccentric butterfly valve (hard against hard)

Product introduction

Technical features:

1. The hard sealing butterfly valve adopts the three eccentric hard sealing structure, with almost no wear between the valve seat and the butterfly plate, and has the sealing function of tighter and tighter.

2. The sealing ring is made of stainless steel, which has the dual advantages of metal hard seal and elastic seal. It has excellent sealing performance, corrosion resistance and long service life under the conditions of low temperature and high temperature.

3. The sealing surface of butterfly plate adopts surfacing cobalt based cemented carbide, which is wear-resistant and has long service life.

4. The large-size butterfly plate adopts quilted frame structure, with high strength, large overflow area and small flow resistance.

5. According to the needs of users, the hard sealing butterfly valve of the valve supply network can be designed with two-way sealing function. It can be installed in any direction without the restriction of medium flow direction or the influence of spatial position.

6. The driving device can be installed in multiple stations (rotating 90 ° or 180 °), which is convenient for users.
