STERILE-SEAL® Butterfly Valves

Valves for Sterile Processes

These valves are used in applications where sterile processes need to be maintained in the pharmaceutical and food industries without unnecessary and costly overhauls and replacement. The special characteristic of this valve is its external sterilization capability. The design is such that the critical "dead" areas of the valve, as well as the disc, body liner, and seals, can be sterilized with steam without coming in contact with the process medium.
