PP Flanged Diaphragm Valve

Type-14 Flanged Diaphragm Valve (1/2 - 4 in.) 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 slurries. 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 three-layer diaphragm, includes a 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 from solid thermoplastic materials. The type-14 diaphragm valve can be pneumatically or electrically actuated. Ideal Applications Include: Throttling, slurry lines, chemical processing, bleach plants, aquariums, mining, water treatment, landfills, swimming pools, semiconductor manufacturing Features & Benefits: Bubble tight sealing even in applications such as slurries or suspended particles, bonnet seals to protect internals from corrosive environments, built-in travel stop to prevent over-tightening or compressive strain on diaphragm, position indicator at top of valve, PVDF gas barrier (protects EPDM backing from gas permeation) standard on all valve with PTFE diaphragm. Flanged (ANSI) face-to-face dimensions are equivalent to most commonly used metallic valves Rugged body and bonnet are of solid thermoplastic for maximum corrosion resistance Uniquely designed body and bonnet together with diaphragms of new sealing designs by computer dynamic analysis for superior sealing Weir design for excellent throttling Bubble-tight sealing, even in applications such as slurries or suspended particles Bonnet seals to protect internals from corrosive environments Built-in travel stop to prevent over-tightening or compressive strain on diaphragm Integrally molded bottom stand for simple yet firm panel mounting Indicator at the top for indication of valve position and prevention of over-tightening PVDF gas barrier, which protects EPDM backing from gas permeation, is standard for all valves with PTFE Diaphragm Low profile Bayonet structure to connect compressor and diaphragm easy diaphragm replacement Type-15 Diaphragm Valve (5 - 6 in.) Multiturn valve good for flow control and use with viscous/slurry lines due to their high resistance to clogging. These valves have a uniquely designed body and bonnet, as well as a diaphragm with new sealing designs, by computer aided analysis for superior sealing. Ideal Applications Include: Throttling, slurry lines, chemical processing, bleach plants, aquariums, mining, water treatment, landfills, swimming pools, semiconductor manufacturing Features & Benefits: Bubble tight sealing even in applications such as slurries or suspended particles, bonnet seals to protect internals from corrosive environments, built-in travel stop to prevent over-tightening or compressive strain on diaphragm, position indicator at top of valve, PVDF gas barrier (protects EPDM backing from gas permeation) standard on all valve with PTFE diaphragm. Flanged face-to-face dimensions are equivalent to those of Type-G diaphragm valve Rugged body and bonnet are of solid thermoplastic for maximum corrosion resistance Bubble-tight sealing, even in applications such as slurries or suspended particles Weir design for excellent throttling Uniquely designed body and bonnet together with diaphragms of new sealing designs by the state-of-the-art computer aided analysis for superior sealing Bonnet seals to protect internals from corrosive environments Built-in travel stop to prevent diaphragm from being over-tightened Indicator at the top for valve position and prevention of over-tightening PVDF gas barrier, which protects EPDM backing cushion from gas permeation, is standard for all valves with PTFE diaphragm Type-G Flanged Diaphragm Valve (8 - 10 in.) Multiturn valves good for flow control and use with viscous/slurry lines due to their high resistance to clogging. The Type-G is the largest of the Asahi diaphragm valves, available only in 8 and 10 in. sizes with flanged end connections. Ideal Applications Include: Throttling, slurry lines, chemical processing, bleach plants, aquariums, mining, water treatment, landfills, swimming pools, semiconductor manufacturing Features & Benefits: Bubble tight sealing even in applications such as slurries or suspended particles, bonnet seals to protect internals from corrosive environments, built-in travel stop to prevent over-tightening or compressive strain on diaphragm, position indicator at top of valve, PVDF gas barrier (protects EPDM backing from gas permeation) standard on all valve with PTFE diaphragm.
