Product Introduction:
The pneumatic flanged butterfly valve is assembled from a flanged butterfly valve body and a rotary pneumatic actuator, enabling remote automated control of the valve via air supply.
The butterfly plate rotates from 0° to 90° to cut off the pipeline medium or regulate flow; the flange connection ensures secure installation and facilitates easy disassembly and maintenance.
It can be equipped with accessories such as solenoid valves, air supply triplet units, limit switches, and pneumatic positioners.
Available in two main types—on/off and regulating—it is widely used in automated pipelines in water supply and drainage, HVAC,
environmental protection, chemical, and thermal industries, and is a mainstream valve in fluid control systems.
Advantages:
1. Pneumatically driven, rapid response
2. Rigid flange connection
3. Flexible configuration options
4. Excellent flow performance
5. Safe and reliable, suitable for explosion-proof environments
6. Easy maintenance
7. Standardized interfaces
