Pneumatic Wafer Butterfly Valve
Compact and lightweight design with pneumatic actuator for 90-degree disc rotation, suitable for medium/low-pressure pipeline on-off and throttling.
Inquire NowProduct Overview
The wafer butterfly valve sandwiches between two pipe flanges, offering a compact, lightweight, and cost-effective solution for on-off and throttling service. The pneumatic actuator rotates the disc 90 degrees for fast, reliable operation in medium to low-pressure systems.
Commonly available in sizes DN40 to DN1200, these valves are suitable for water, air, oil, and non-aggressive chemical media.
Key Features
- Compact & Lightweight: Wafer body fits between flanges, reducing weight and installation space
- Fast Operation: 90-degree rotation provides quick open/close
- Cost Effective: Simple design with fewer parts reduces initial and maintenance costs
- Versatile Seats: EPDM, NBR, PTFE, and Viton seat options for different media compatibility
- Bi-Directional: Seals in both flow directions
