Frequently Ask Questions
A Straight Through Diaphragm Valve is a diaphragm valve with a relatively unobstructed flow passage designed to allow fluids, slurries and suspended solids to pass through the valve with minimal restriction.
The diaphragm provides shut-off while separating the process fluid from the valve's operating mechanism.
The absence of a pronounced internal weir gives the valve a more open flow passage, reducing the likelihood of solids accumulating around an internal obstruction.
This makes it particularly useful for slurry and abrasive services.
The valve should be isolated from the process, depressurized and serviced according to the manufacturer's maintenance procedure. A worn or damaged diaphragm should be replaced.
Its biggest advantage is the unobstructed flow passage, which makes it particularly suitable for slurry, abrasive fluids and media containing suspended solids.
Alis Valves is a Straight Through Diaphragm Valve manufacturer and supplier in India, offering valve solutions for mining, slurry handling, chemical processing, wastewater, cement, pulp & paper and other demanding industrial applications. The straight-through design is particularly suitable for applications involving abrasive, viscous and solids-containing media.
