Description

Type-14 Flanged 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 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
Note: Actuated and Flanged connection valves are special order with a 3-4 week average lead time.
