Features
1. the valve adopt three eccentric struture.No war between the valve seat and valve plate, with more and more tightly sealing funtion.
2. The sealing ring of this butterfly valve are metal elastic sealing and metal seals which make the valve with bilateral direction sealing. All with excellent sealing properties, resistant to corrosion, long service life both in low pressure and high temperature.
3. The sealing surface of the disc is welding of cobalt-based alloy, with the advantage of wear resistance, long service life.
4. There is a two-way sealing function of the valve.No restriction from the media flows and spatial location, which can be installed in any direction.
5. The driving device can be installed multi-bit(rotation 90°or 180°), easy to use.
