GEMU Model 657 Full-Bore (Straightway) Industrial Diaphragm Valve
The Gemü Metallic Body Full-Bore (Straightway) Diaphragm Valve is produced to numerous world
standards. Gemu Full-Bore (Straightway) valves are available from 1/2” to 14”. Due to the valves straight through bore design it is ideal for applications handling materials that can set-up in the piping
and as a result require pipe to be rodded or brushed out. In these instances, the valve does not
need to be removed from the piping nor does it require disassembly. The Gemu Full-Bore (Straightway)
valve is ideally suited for services requiring high flow volumes or are inherently sluggy,
fibrous, abrasive, corrosive/abrasive or high viscosity fluids.
The Gemü Full-Bore (Straightway) valve is an ideal solution because the media only comes in contact with
the body/lining and the diaphragm. This range is more economical than alternate valve concepts
for low pressure flow control applications and has no internal cavities or crevices to entrap process
fluids. The Gemü Full-Bore (Straightway) valve can also be installed to be self-draining.
