Product Overview

The pneumatic high-performance double eccentric butterfly valve is composed of a piston-type cylinder and a double eccentric butterfly valve. Optimized and upgraded on the basis of the single eccentric butterfly valve, its structural feature is that the valve shaft center deviates from both the butterfly disc center and the valve body center. This unique double eccentric design enables the butterfly disc to quickly separate from the valve seat after the valve is opened, which greatly eliminates unnecessary excessive extrusion and friction between the disc and the seat, effectively reducing wear and extending the valve service life.

Structural Features

1. Dual-function design for high-performance control and cut-off, serving as both a control valve and a shut-off valve to meet diverse pipeline working requirements.

2. Delivers excellent isolation performance for gas and liquid media, paired with stable and precise flow control characteristics.

3. Minimal friction during valve opening and closing at the valve seat, no jamming failure, ensuring long-term stable operation and prolonged service life.

4. Equipped with an easily replaceable and adjustable sealing ring, facilitating daily maintenance and flexible sealing performance calibration.

5. Features low operating torque and reliable torque shutoff performance, ensuring stable and labor-saving valve operation.

6. Customizable fireproof structure is available according to customer on-site working condition requirements.
