The McCanna butterfly valve is a device renowned for its reliability, functionality and design.  The McCanna butterfly valve features off-centered disc, stem seal, steam bearing and unique seat design.  By this very design, the Hills McCanna butterfly valve is able to handle a range of operating conditions, including exposure to corrosive chemicals, acids, gases, alkalies, hydrocarbons, water and a variety of other fluids.  This valve is suitable for many specific services, including vacuum, steam, nuclear, oxygen, cryogenic, sour gas, double block/bleed, as well as dry chlorine in gas or liquid forms.

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 allow for 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.
