NOTE 1: for optimum operation it is recommended that the hot and cold water supply pressure be balanced to /- 10%
NOTE 2: Notwithstanding the above, compliance with AS/NZS3500 must be maintained.

FLOW SIZING GRAPH
The Galvin
Engineering CliniMix
®
Thermostatic Mixing Valve is suitable for many applications. The Head-loss
Characteristic for Mixed Outlet Flow rate versus Balanced Inlet Pressure is shown below in Graph below. It is important
that the valve is not oversized for its intended application.
GRAPH
– Head-loss Characteristics
NOTE: To ensure optimum performance the minimum
outlet flow of the TMV 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
AS/NZS 3500.1
The pipe-work between the TMV and the system must be
sized in accordance with AS/NZS 3500.1 to ensure the
water velocity in the pipe-work is within the allowed limit.
If the TMV is to be installed and operated under unequal
inlet pressures, the lower inlet pressure determines the
outlet flow rate. However, for optimum performance and
stability it is recommended that the TMV be installed
with balanced dynamic inlet pressures (+/- 10%).
