Function
The thermostatic mixing valve is used in systems producing domestic
hot water or in radiant heating systems. Its function is to maintain the
temperature of the mixed water supplied to the user at a constant set
value when there are variations in the supply pressure and temperature
of the incoming hot and cold water or in the flow rate.
The 5231 series thermostatic mixing valves are ASSE 1017 approved for
point of distribution and are designed specifically for systems requiring
high flow rates and precise, stable temperature control. Optional
stainless steel inlet port check valves are available separately, for field
installation only.
Product range
5231 series thermostatic mixing valve. NPT male and sweat union
connections, sizes 1", 1-1/4", 1-1/2", 2". Inlet port check valve s and
outlet temperature gauge optional.
