Double Flange Concentric Butterfly Valve
Description:
The most common type of butterfly valves are of "concentric" design: the turning axis and axial alignment of the disc are both centered with the valve body. Most concentric butterfly valves achieve sealing by compressing the edge of the disc against an elastomeric valve seat. This type of sealing is often referred to as "resilient seated" butterfly valves.
Features：
· Extended life span of valve and seals with unique wave line seat and special disc shape
· Reduced torque from wave seal and disc design reduces size of actuator, lowering the cost
· Increased flow capacity with unique profile disc and two piece shaft design
· Valves direct mount to actuator using standard ISO5211 international standards
