Type-14 Flanged Diaphragm Valve (1/2" – 4")
The Type-14 diaphragm valve features improved body to bonnet sealing performance, visual position indication, weir design for excellent throttling capabilities and built in travel stop to prevent over-tightening and eliminate compressive strain. Bubble tight sealing can be achieved even in tough applications containing suspended particles or slurrys.
Asahi's Type-14 diaphragm valve features a layered EPDM/PTFE diaphragm which can accept the addition of a PVDF gas barrier for aggressive chemicals such as Sodium Hypochlorite. These aggressive chemicals produce an off-gas that can permeate the typical laminated PTFE layer and actually become delaminated in this highly corrosive environment leading to a potentially hazardous situation. The Type-14's 3-layer diaphragm which includes the gas barrier layer, prevents this from ever occurring. The Type-14 diaphragm valve body is of 1-piece molded construction and is not fabricated. For maximum corrosion resistance, the Type-14 diaphragm valve's rugged body and bonnet are manufactured of solid thermoplastic materials. The Type-14 diaphragm valve can be pneumatically or electrically actuated.
