Hills McCanna Butterfly Valve
The unique off-centered disc design of the McCanna and Hills McCanna butterfly valve guarantees lower operating torque and less seat wear. The incorporation of stainless steel taper pins allows perfect disc closure and enables the off-center design to form a cam-like action. This motion releases the disc from its TFE seat and prevents unwanted disc drag and averts seat deformation.
Material build-up from slurries and suspended solids is eliminated by the wiping action of the disc works.
