Function

The 167 series HydroMixer™ provides a modulating three-point

floating type non-spring return motorized three-way mixing valve

to regulate the fluid temperature in heating and air conditioning

systems in response to a separately-sourced outdoor reset controller.

It comes complete with onboard three-speed or variable-speed

pump, motorized three-way mixing valve, check valve, supply and

return temperature gauges, secondary circuit shut-off ball valves

and pre-formed insulation shell. Versions are available with either the

three-speed Grundfos UPS 15-58 pump or the variable-speed Alpha

25-55U pump.

The unit can be ordered with supply flow and pump on the right or left

side. The adjustable differential pressure by-pass valve, code 519600

and wall bracket code 165001 are optional. The unit comes with male

union connections which require separately purchased, 1 inch sweat

or NPT, top outlet and bottom inlet fitting kits.
