Manual Plastic Diaphragm Valves

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

Asahi/America's Type-G flanged diapgragm valves are multiturn valves that are 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.
