A great solution for aseptic applications, this valve series utilizes a stem flush adapter to provide a liquid or steam barrier around the valve stem.
The W80 adapter has an outer perimeter seal to the valve body with an o-ring that is located forward to the
product zone to minimize crevices. The product stem passes through the adaptor and is sealed in the upper part and the lower part of the adaptor with o-rings.
The W80A adapter provides the additional functionality to run a sterile flush on the body to adapter o-ring seal.
