800 series high-performance clamp type ..

Adopting a double eccentric butterfly plate with a spherical sealing surface and a single flexible lip seal seat, it is suitable for occasions that require reliable sealing and good adjustment characteristics. Due to the design of the double eccentric butterfly plate, this valve has tight sealing performance and a long service life. Can be used to quickly cut off or adjust flow.
The product is suitable for the transportation of liquids and gases (including steam) in various industrial pipelines. Specially selected, it can also be used for special media such as chlorine, oxygen, high vacuum, sulfur resistant or corrosive media. The product can also have a fire-resistant structure for selection.
The connection method can adopt a clamp type or a protruding single flange design for large pipe diameters and pipeline terminations.

The applicable temperature depends on the material, pressure, and valve specifications. Our company offers a variety of valve bodies and sealing materials to choose from, providing valves with a wider temperature range.

Valve characteristics

Using a single PTFE valve seat design, it has good elasticity and high reliability
The lip type sealing structure can compensate for changes in temperature and pressure.
Long service life and low maintenance workload.
● Achieve bubble free sealing in both directions.

Design of eccentric shaft and eccentric butterfly plate
When opened and in the middle position, the valve seat does not come into contact with the butterfly plate.
There are no wear points on the upper and lower parts of the valve seat.
Low torque and small requirements for the operating mechanism.

Capable of both interruption and control
Has excellent control characteristics.
The flow characteristic curve changes proportionally.
● Wide adjustment range.
Even when used for control, it can still be tightly sealed.
