Flow Capacity
| Valve | Inlet Size | 5 PSI | 10 PSI | 20 PSI | 30 PSI |
|---|---|---|---|---|---|
| Neptune EMX 125 | 1-1/4" | 41.4 GPM | 58.6 GPM | 83 GPM | 101 GPM |
Capacity values shown above correspond to the listed pressure drop across the valve.
Typical Installation
Install the mixing valve below the hot water tank or water heater. If this is not possible, install a heat trap with an approximate 2 ft. drop as shown in the installation diagram.
Connect a tempered-water return line as shown in the installation diagram. This allows flow through both ports of the mixing valve during periods of no draw.
If a dual-temperature system is used, a separate recirculation loop and pump are required to return high-temperature hot water to the water heater. Install the water heater according to the water heater manufacturer's instructions.
