Automatic Balancing Valves
IMI Flow Design is the established leader in quality and innovation for automatic balancing valves and owns many patents, including several for constant flow regulators.
IMI Flow Design products rely on stainless steel for all parts that flex or slide.
IMI Flow Design’s patented consolidated ports and patented hybrid ports provide the best chance in the industry for debris to pass through without causing a problem.
Several patented IMI Flow Design technologies improve performance at low differential pressure, thus saving energy as compared to the competition.
All IMI Flow Design regulators are precision machined and skillfully assembled in a process that includes continuous flow testing to eliminate errors.
These features and others make IMI Flow Design’s product the most reliable in the industry.
Manual Balancing Valves
ASHRAE recommends that manual balancing valves be placed on the coils, risers, branches, and pump discharge so that the system can be proportionally balanced. This method is preferred by most designers for constant speed systems. Proportional balancing strives to have all circuits with pressure drop equal to the index circuit which already has the most loss. In the typical layout, the index circuit is highlighted. When proportional balancing is complete, the design GPM is achieved by trimming the pump impeller or throttling the pump balancing valve.
Coil Hook-up Kits
IIMI Flow Design offers Pre-configured Automatic and Manual Coil Hook-up Kits. Any combination of standard or custom coil hook-up kits can be assembled to fit your hydronic system requirements. These kits consist of automatic and manual balancing valves, combination ball valve with strainers, and union with manual vent and PT ports, and hoses if required.

VersaFlow
VersaFlow Hose kits come in 4 different hose pack combinations.
- Kit A features the AutoFlow automatic balancing valve on the return side of the coil as recommended by ASHRAE. Automatic balancing offers a number of advantages over manual or differential temperature balancing.
- Kit B has a manual balancing valve on the return side of the coil as recommended by ASHRAE. The VersaFlow manual balancing kit features a calibrated venturi valve instead of a circuit setter. The venturi has a number of advantages over the circuit setter.
- Kit C includes a Model UB ball valve, Model YC strainer with ball valve and two Model S2/S3 hose assemblies.
- Kit AC includes Model AC combination AutoFlow regulator with dual P/T ports and shut off valve and Model YC strainer with ball valve and two Model H2/H3 hose assemblies.
