Operating principle

The thermostatic mixing valve mixes the hot 
and cold water at the inlets to maintain constant 
mixed water at the desired set temperature. A 
thermostatic sensor (1) is fully immersed in 
the mixed water outlet passage (2) which, 
as it expands or contracts, continuously 
establishes the correct proportion of hot and 
cold water entering the valve. The regulation 
of these flows is by means of a piston (3) 
sliding in a cylinder between the hot and cold 
water passages. This controls the passage of 
hot (4) or cold (5) water at the inlet. If the inlet 
temperature or pressure changes, the internal 
element automatically reacts to restore the set 
temperature at the outlet. The AngleMix 520 
series point of distribution mixing valve is an 
angled configuration for easy installation to 
most water heaters for direct mounting to the 
top pipe connections.
