PVC Type-14 Diaphragm Valve

Type-14 True Union Diaphragm Valve 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 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. 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. True union design permits installation or repairs without expanding pipeline Rugged-square body and bonnet are of solid thermoplastic for maximum corrosion resistance Uniquely designed body and bonnet together with diaphragms of new sealing designs by the state-of-the-art computer aided analysis for superior sealing Weir design for excellent throttling Full-vacuum rated Bonnet seals to protect internals from corrosive environments Adjustable travel stop to prevent diaphragm from being over-tightened Bayonet structure to connect compressor and diaphragm for quick maintenance Integrally molded bottom stand for simple yet firm panel mounting Indicator at the top for valve position PVDF gas barrier, which protects EPDM backing cushion from gas permeation, is standard for all valves with PTFE diaphragm Low profile Asahi Part Numbers: 1526005, 1527005, 1526007, 1527007, 1526010, 1527010, 1526012, 1527012, 1526015, 1527015, 1526020, 1527020, 1528005, 1529005, 1528007, 1529007, 1528010, 1529010, 1528012, 1529012, 1528015, 1529015, 1528020, 1529020
