Feature
1. Compact structure: low volume, light weight and easy maintenance
2. Smooth flow channel: low flow resistance, low pressure drop and high flow
3. Three-eccentric multi-level compound seal butterfly valve: It uses the unique cam effect, so that during the valve's 90 ˇtravel the seat is totally disengaged from the disc seal ring without any friction.
   Three-eccentric soft seal butterfly valve: The sealing pair is made of integral PTFE materials, which are suitable for applications with high medium cleanliness, frequent valve on-off and high requirements for sealing pair corrosion resistance. Especially it can ensure that its service life is basically the same as that of the pipe in the thermal system.
   Three-eccentric metal seal butterfly valve: The sealing pair adopts a full metal seal structure. The sealing pair adopts a "hard-contact-hard" structure as shown in figure 1 pneumatic three-eccentric butterfly valve. The seal has a long service life. It is suitable for service conditions where the medium working temperature is extreme, the erosion is severe and there is the occurrence of "crystallization".
4. Strong anti-wear performance: The disc adopts a three-eccentric structure and the sealing face is subject to hard alloy overlaying welding with good anti-wear performance.
5. Valve flow characteristics: Approximate equal percentage. Control and shut-off can be realized.
