Diaphragm Control Valve:
Diaphragm Control Valve are used on shut-off and throttling service for liquids, slurries and vacuum/gas. The seal is achieved by a flexible membrane, usually elastomer, and possibly reinforced with a metal part. This makes this valve suitable for viscous flows and also hazardous, abrasive and corrosive flows as its sealing system avoids any contamination towards or from the environment.
They are well suited to the handling of multiple chemical applications both clear fluids as well as slurries. The diaphragm valve has an extended use for applications at low pressures and slurry fluid where most other kinds of valves corrode or become obstructed.
From 0.5″ to 14″.
Connection to the pipe:
Butt-weld, Clamp, Flange, Screwed, Socket and Spigot Weld.
