Pneumatic double eccentric high-performance butterfly valve

Pneumatic double eccentric high-performance butterfly valve

The product is suitable for the transportation of liquids and gases (including steam) in various industrial pipelines. After selection, it can also be used in special media such as chlorine, oxygen, high vacuum, sulfur resistant or corrosive media. The product can also have a fireproof structure for selection. Adopting a double eccentric butterfly plate with a spherical sealing surface, paired with a single piece flexible lip seal seat, suitable for occasions requiring reliable sealing and good adjustment characteristics. Due to the design of the double eccentric butterfly plate, the valve has tight sealing performance and long service life. It can be used for quickly cutting off or adjusting flow. The seat of the dual eccentric high-performance butterfly valve is sealed with PTFE material, and the valve can achieve ANSI Class VI zero leakage. Suitable for gas transportation and process media with high requirements for valve life, with a normal service life of up to times. The outside of the valve seat is a movable insert that is fixed by a spring. The tighter the flange clamp and the greater the pressure, the better the sealing performance of this high-performance butterfly valve. The dual eccentric high-performance butterfly valve adopts a dual eccentric butterfly plate with a spherical sealing surface, paired with a single piece flexible lip seal seat, suitable for occasions requiring reliable sealing and good adjustment characteristics. Due to the design of the double eccentric butterfly plate, this high-performance butterfly valve has tight sealing performance and an ultra long service life. It can be used for quickly cutting off or adjusting flow.

Products Details
Pneumatic high-performance butterfly valve performance:

1. There is no need to add O-rings and metal components to assist in sealing. The lip type sealing structure has almost no friction during sealing, which can compensate for changes in temperature and pressure on the valve, ensuring smaller torque and sealing performance.

2. The dual eccentric high-performance butterfly valve uses a single PTFE seat design, with good elasticity and high reliability. The lip sealing structure can compensate for temperature and pressure changes. Long service life and minimal maintenance.
3. A complete series of anti-static guide device structures with low operating torque.
4. It has excellent control characteristics with both interruption and control. The flow characteristic curve varies proportionally. Wide adjustment range. Even for control, it can still be tightly sealed.
5. The full diameter has passed the API 607 fire test regulations, ensuring safe fire protection under special working conditions and a long service life.
6. Adopting a dual eccentric structure design of eccentric shaft and eccentric butterfly plate, the valve seat does not come into contact with the butterfly plate when opened and in the middle position. There are no wear points on the upper and lower parts of the valve seat. Low torque and low requirements for the operating mechanism.

7. The connection methods include wafer type and single flange type.
