Dharmi Engineers supplying Diaphragm Valves for different applications such as slurries, Viscous and corrosive substances, suspended solids and other hard to handle medium. Dharmi Diaphragm Valve having rugged design incorporating the best material available is proved by maintenance free operation. Dharmi Diaphragm valve design is very simply construction. The valve assembly has only three major parts such as Body, Bonnet & Diaphragm. In the diaphragm valve,
it's also very easy to replace the rubber diaphragm without dismantling body from the line.
Extra heavy duty casting affords high resistance to atmospheric corrosion. Dharmi diaphragm valve reduces diaphragm travel for extended service and fine control. |
