Las válvulas de diafragma ofrecen muchas combinaciones de materiales de diafragma de cuerpo y elastómeros, se pueden operar manualmente, eléctricamente o neumáticamente, son resistentes a la abrasión y no se obstruyen. Las suspensiones a baja presión que normalmente obstruyen la mayoría de los otros diseños de válvulas, pasan fácilmente a través de una válvula de diafragma. Ademas su diseño de entrada superior, permite el mantenimiento en línea, siendo adecuada para el servicio de estrangulamiento y ON / OFF en aplicaciones que van desde el tratamiento de agua hasta procesos de abrasión química

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" sizes with flanged end connections.

Ideal Applications Include: 

Throttling, slurry lines, chemical processing, bleach plants, aquariums, mining, water treatment, landfills, swimming pools, semiconductor manufacturing

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.

Features/Benefits:

• Rugged body and bonnet of solid thermoplastic for maximum corrosion resistance

• 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 diaphragm from being over-tightened

• Indicator at the top for valve position

• PVDF gas barrier, which protects backing cushion from gas permeation, is standard for all valves with PTFE diaphragm
