TypeG-Diaphragm

Manual Plastic Diaphragm Valves

Type-G Flanged Diaphragm Valve (8" – 10")

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

Specifications

Sizes:

8" – 10"

Body Materials:

PVC, PP and PVDF

Bonnet Materials:

PVC, PP, PPG and PVDF

Diaphragm:

EPDM and 3-Layer EPDM/PVDF/PTFE
Also available in Nitrile

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.

  • 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

Actuation

  • Century Pneumatic Actuator (Please call for datasheet)
