"Center type / Concentric Butterfly Valves"
The disc and shaft are connected without pin to reduce the leak point and achieve on-site replacement. It also can achieve optimal fit and open torque transmission by using O-ring sealing on the shaft.
Ball-type sealing is adopted by the connection of Disc and Seat ensuring better connection of Disc and Seat, better sealing capacity and low torque.
The semi-shaft design of the Disc efficiently lowers the pressure loss of the valve.
The seat has no skeleton. It adopts a bar design and uses thick rubber, which improve the rebound resilience, alowing lower torque, and the interference sealing ensures better sealing results. The seat can be designed by multiple rubber materials to adopt different working condition.
The bushing between the shaft and body minimizes the friction and lower the torque value, increasing the valve lifetime.
The structure of this concentric butterfly valve is simple and therefore easy to use.

Butterfly Valves - BUV13 Fully Lined
Features BUV13
"Full lined Butterfly Valves"
Concentric Butterfly Valve
The valve is rubber lined by vulcanization injected directly on the body to ensure permanent adhesion.
The use of the adhesive layer will enhance the reliability of the butterfly valve.
Precision encapsulation and molding process can ensure the lining sealing of the disc and integral flange gasket sealing.
With polishing and precision machining on the sealing
surface of the disc, the valve is completely sealed, it lowers the operating torque, extends the service life and reach bubble-tight grade sealing. Streamlined design also minimizes pressure loss.
