Manual Plastic Diaphragm Valves
Type-14 Flanged Diaphragm Valve (1/2" – 4")
The type-14 diaphragm valve has been specified with confidence since 2002. Design features include industry-leading body-to-bonnet sealing performance isolating the bonnet components from the media, high visibility position indication with built-in travel stop providing visual confirmation while minimizing compressive strain across the diaphragm, and smooth ergonomic handle operation. Bubble-tight sealing can be achieved even in tough applications containing suspended particles or slurries. Controlled flow characteristics are achieved by way of an internal weir design, requiring fluid to flow over the raised center section of the body where the body and diaphragm meet. The molded thermoplastic valve body and diaphragm are the only components in contact with the media.
Asahi's type-14 diaphragm valve features a three-layer EPDM/PVDF/PTFE diaphragm providing a gas barrier protecting the bonnet internals from aggressive off-gassing chemicals such as sodium hypochlorite. The Type-14 diaphragm valve body is of one-piece molded flanged construction, which provides a shorter overall dimension and fabrication-free body construction.
For maximum corrosion resistance, the type-14 diaphragm valve's body and bonnet are manufactured from solid thermoplastic materials. The type-14 diaphragm valve can be pneumatically or electrically actuated.
