Bubble tight sealing can be achieved even in tough applications containing suspended particles or slurries.\u003c\/p\u003e\n\u003cp\u003eAsahi'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 three-layer diaphragm includes the gas barrier layer, which prevents this from ever occurring. The type-14 diaphragm valve body is of one-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.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eIdeal Applications
