Characteristics
This pneumatic high-performance butterfly valve has fast response and automatic control capability. Its triple eccentric metal seal achieves friction-free operation and zero leakage. It resists heat, pressure, abrasion and corrosion effectively. Safe for combustible media, the compact design ensures easy installation and low maintenance.

Advantages
1.Fast Pneumatic Operation & Automation
This metal to metal butterfly valve equipped with pneumatic actuator, the valve opens and closes quickly. This pneumatic butterfly valve supports remote control and frequent operation, perfectly matching automatic pipeline systems.
2.Superior Sealing & Durability
TThe triple-offset structure eliminates seal friction. Metal hard seal ensures zero leakage. It stands up to high temperature, high pressure, abrasion and corrosive media.
3.High Safety & Low Maintenance
Pneumatic drive guarantees safe operation even for flammable and explosive fluids. The robust structure reduces failure rate and cuts long-term maintenance costs.
Packing
Standard export wooden case packaging

Application Scenarios
The high performance wafer butterfly valve is extensively applied in power, petrochemical, metallurgy, heating and environmental protection industries. Suitable for automatic pipelines conveying steam, flue gas, thermal oil, corrosive media and combustible gas under high temperature and high pressure conditions.
