Hot Water Mixing Valves - Constant Pressure Expansion Valve.
Hot Water Mixing Valves
mixing valves
- (Mixing valve) A Thermostatic Mixing Valve (TMV) is a valve that blends hot water (stored at temperatures high enough to kill bacteria) with cold water to ensure constant, safe outlet temperatures preventing scalding.
- (Mixing Valve) attached to the tip of the faucet to mix hot and cold running water.
- (Mixing Valve) Multi-inlet valve used to mix two or more fluid intakes to give a mixed product of desired composition.
hot water
- Water heating is a thermodynamic process using an energy source to heat water above its initial temperature. Typical domestic uses of hot water are for cooking, cleaning, bathing, and space heating. In industry, both hot water and water heated to steam have many uses.

Valve
The valves isolators in the plant room of Victoria Baths. Manchester. I missed the part where the chap was explaining the history of it, so I'm guessing these controlled the supply of hot water into the pools. Edit: I got the days mixed up and ended going on Saturday instead of Sunday, mixed in with a bunch of total strangers. The upshot of it, I got to go into the boiler room and basement, which wouldn't have been possible otherwise.
Mixing Valve orientation
This photo shows incorrect orientation of the mixing valve. For correct orientation the blue dot must be aligned with the cold water side. Likewise the red dot corresponds to the hot water side. Output water temperature is adjusted with the black knob. The coupling is replaced with 1/2" copper tubing to maintain correct spacing to fit the tank.
