pneumatic wafer butterfly valve Description
Pneumatic wafer butterfly valve is an automated valve that integrates pneumatic actuators on the basis of traditional wafer butterfly valves. It drives the butterfly plate to rotate 90° through compressed air to achieve rapid opening and closing or flow regulation. It is suitable for fluid control in natural gas, chemical, food and other industries. Its core feature is the combination of wafer connection (no independent flange) and pneumatic drive, with compact structure and remote control capability, suitable for medium and low pressure conditions with temperature ≤425℃ and pressure ≤PN10MPa.

Advantages and Disadvantages of Pneumatic Wafer Butterfly Valve
Advantages
Fast response speed: Pneumatic drive opening and closing time is less than 2 seconds, and the emergency shutoff efficiency is higher than that of manual valves.
Zero leakage design: The three-eccentric seal structure still maintains sealing under 10MPa pressure, and the service life is up to 100,000 times of opening and closing.
Remote control: Supports DCS/PLC integration to achieve unmanned operation.
Limitations
Air source dependence: A stable compressed air supply is required, and humidity or impurities may affect the life of the actuator.
Maintenance complexity: The valve needs to be disassembled for sealing ring replacement, and the maintenance time is higher than that of flange butterfly valves.
Application of Pneumatic Wafer Butterfly Valve
Petrochemical Energy
Quick shutoff of natural gas pipelines, three-eccentric seals are resistant to corrosion by sulfur-containing media.
Food and Pharmaceuticals
Sanitary stainless steel valve body + PTFE seal, meeting GMP clean requirements.
Water treatment system
Large flow water supply and drainage network adjustment, rubber seals achieve zero leakage and low maintenance cost.
