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

Asahi/America’s Type-G flanged diaphragm 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.
