Flow Sizing Graph
The ENWARE AQUABLEND 2500 Thermostatic Mixing Valve is
suitable for many applications. The Headloss Characteristic for
Mixed Outlet Flowrate versus Balanced Inlet Pressure is shown
Graph 2.1 below. It is important that the valve is not oversized
for its intended application.

Note: To ensure optimum performance the minimum outlet flow
of the mixing valve during operation should be at least
6 litres/minute.
It is important that the valve is sized such that the flow rates
from the outlets are not less than those listed in AS3500.1. The
pipework between the valve and the system must be sized in
accordance with AS3500.1 to ensure the water velocity in the
pipework is within allowed limits.
If the valve is to be installed and operated under unequal inlet
pressures then it is the lower inlet pressure that will determine the
outlet flow rate. However, for optimum performance and stability
it is recommended that the valve is installed with balanced
dynamic inlet pressures (+/- 10%).
