SpecialityvalveSuction Diffuser Manufacturer in India.

Specialityvalve is India’s leading manufacturer of valves. Specialityvalve produce Suction Diffuser manufacturer in India. The Suction Diffuser Plus, manufactured by Specialityvalve, is a straightening fitting with an angle pattern that allows the pumping system to perform optimally in India. It conditions the flow into the pump suction in order to keep the pump running as efficiently as possible.


Suction valves are manufactured by Specialityvalve, a market leader. Diffuser valves allow the pumping system to operate at its peak performance levels. It conditions the flow into the pump suction in order to maximize pump efficiency. Furthermore, it saves space by eliminating the need for straight lengths of pipe leading into the pump while also acting as an elbow to allow for a close transition between return piping and the pump suction. To prevent large sediment or debris from entering the pump, the large orifice cylinder acts as a coarse y-strainer. Finally, the internals are all completely removable, allowing for quick and easy field service.
