A Weir Type Rubber Lined Diaphragm Valve Flanged End

Nivz Valves & Automation manufactuing Diaphragm Valves for different applications such as slurries, Viscous and corrosive substances, suspended solids and other hard to handle medium.

Nivz Diaphragm Valve having rugged design incorporating the best material available is proved by maintenance free operation.

Nivz A Weir Type 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. Nivz diaphragm valve reduces diaphragm travel for extended service and fine control.

A wide choice is available in body materials, body rubber lining, types of operation and body end connection to satisfy the need of most industrial application.

Nivz High quality standards are strictly followed, 100% valve being checked for size, design pressure, operation, Material of Construction, final finish etc. Nivz also offer with PTFE, FEP, PFA, Teflon® lined  Diaphragm Valve for corrosive application.

Nivz valves class one quality Diaphragm Valve Manufacturer, Rubber Lined Diaphragm Valve Exporter, Importer, Supplier, Stockist. A Weir Type - KB Type - Straight Through Pattern Type Diaphragm Valve.
