Diaphragm Valve

You can choose any diaphragm valve at Authorized Parts Inc. This kind of valves are limited to pressure. The fabric-reinforces diaphragms are made by natural rubber or synthetic rubbers faced with Teflon fluorocarbon resin. This is durable and thick. And the purpose of this diaphragm is to protect the material inside the valve from the contents of the pipe. Like for instance in a chemical manufacturing facility that producing hydrofluoric acid ( which dissolves virtually every substance except for certain plastics), a special diaphragm would seal the metal actuator head and valve housing. Otherwise the acid could melt the actuator, burst from the pipe to kill workers and surge uncontrolled. suitable for handling sticky and viscous fluids, slurries and highly corrosive and hazardous substances. It can be operated with air pressure signal. Also riveted to the ceiling of the pipe or squeezed along the edges between two stacked pieces, the diaphragm is flat when at rest. The center is considerably thicker and often reinforced with mesh fibers, meanwhile the edges are thinner for easier stretching.

Authorized Parts Inc. have different kinds of Diaphragm Valves. They have their Lined Diaphragm Valves that offers the advantage of in-line service for critical applications when the need arises for a replacement diaphragm. Also they have Glass Lined Diaphragm Valve and Flanged Diaphragm Valve. Visit their website today for more details.
