Thermostatic safety valve JBV1

Thermostatic safety valve JBV1
This thermostatic recooling one-way valve is designed to protect central-heating heat sources against overheating. The valve in its brass body is controlled by a thermostatic element. When the limit temperature of heating water is reached, the valve opens and lets the cold water from the mains flow in and cool down the heating water in a heat exchanger. Heated cooling water is discharged into the sewer system. As soon as the water temperature drops below the limit, the valve closes. If the pressure in the mains could be above 6 bar, it is necessary to install a pressure reducer at the inlet of cooling water
