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.

Hydraulic characteristics shown account for the presence of ball valves Installation of adjustable differential pressure by-pass valve To mount the differential pressure by-pass valve, insert it in place of the standard spacer. After closing the ball valves using the wrench provided, remove the spacer, as shown in the following figure.
Adjustable differential pressure by-pass valve
519006 Differential pressure by-pass valve for 167 series. Max. operating pressure: 145 psi (10 bar) Max. operating temperature: 212°F (100°C) By-pass differential pressure setting range: 0.3 – 4.3 psi (2 – 30 kPa) Connections : 1” male x 1” male (straight) The adjustable differential pressure by-pass valve ensures the head pressure of the pump is proportional to the number of two-way on/off, modulating or thermostatic valves being closed in the secondary circuit, preventing pump overheating and excessive fluid velocity.
The mounting is different depending on the direction of the discharge flow: - By-pass valve installed with flow direction as indicated below for unit with pump and upward discharge flow to secondary circuit on the right side:
- By-pass valve installed with flow direction as indicated below for unit with pump and upward discharge flow to secondary circuit on the left side:
