IMI Flow Design

IMI Flow Design is a very well regarded manufacturer of piping kits, hose kits, automatic and manual control valves and pressure independent valves. All FDI products are precision machined and flow tested, and by using stainless steel on all parts that flex or slide, FDI balancing devices are high quality and long lasting.

Their latest innovation is “The Equalizer”, an adjustable differential pressure control valve in ½”-6” sizes that isolates the system branch where it’s installed, enabling consistent performance from the control valves and terminal units. KSR now stocks many IMI FDI hose kits and piping assemblies.
