Thermostatic mixing valve for solar thermal systems
The thermostatic mixing valve is used in solar thermal systems that produce hot water for domestic purposes. It is designed to maintain the preset temperature of the mixed water delivered to the user outlet, when there are variations in the temperature and pressure of the hot and cold water at the inlet, or in the drawn-off flow rate.
What is a Pressure Regulating Valve (PRV)?
This is where a pressure regulating valve (PRV) comes in: PRVs are bell-shaped devices located on the main water supply line where the water enters the home, near the shutoff valve. PRVs regulate the pressure in a home and keep it at a safe, steady level.
