  • Pneumatic wafer type butterfly valve description

    Pneumatic wafer type butterfly valve is metal to metal sealing multi-level structure, which is widely used in medium temperature<425°C of metallurgical, power, petrochmical, and municipal construction, drainage and industrial pipe, for regulating traffice and truncated fluid to use. ThePneumatic wafer type butterfly valve adopt three eccentric structure. The Sealing face of the Pneumatic wafer type butterfly valve seat and disc is made of the steel and stainless steel with good corrosion resistance, long useful life. With the two-way sealing function is our high performance wafer type butterfly valve.
  • Pneumatic wafer type butterfly valve feature

    1. the Pneumatic wafer type butterfly valve adopt three eccentric struture.No war between the butterfly valve seat and butterfly valve plate, with more and more tightly sealing funtion.

    2. The sealing ring of this Pneumatic wafer type 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 Pneumatic wafer type butterfly 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.
