Features Applications Model

DEMCO dry journal stem seal system gives absolute assurance of sanitary butterfly valve construction.
Drilled passageways, a design originated by DEMCO, vent the entire interior of the disc to atmosphere. No closed chamber is provided for the culture of undesirable organisms.
Discs are produced from investment castings, smooth and non-porous. Stem bosses are minimized for increased flow.
The projecting inner surface of the resilient seat contacts and is compressed by the mating flange to form a smooth and uninterrupted flow way. This positive seal between the innermost contact of the seat and flange ensure aseptic conditions after a piping flush.
