COVNA Gas Control Wafer Centerline Cast Iron Butterfly Valve With Pneumatic Actuator
- Compact structure, long service life, good sealing performance, easy maintenance, quick detachable and installation
- The pneumatic actuator can be switched on and off quickly when it rotates 90 degrees, easy to operate.
- Stable performance, Widely used in various industries for both on-off and regulating service
- Spherical frictional surface design is adopted at the middle and lower holes of the valve plate. The torque is smaller and the sealing performance is better.
- The seat has no back-to-back design, lighter torque, and is convenient for users to replace the seat by themselves.
