Cast iron thermostatic valve ESBE VTC

Product detailed description

- type VTC 511, 1" and 5/4" internal threads, various designs

- The valve is used for filling storage vessels and in particular to protect the boiler against low temperature corrosion up to 150 kW. Constantly maintaining a higher return temperature means higher boiler efficiency, minimised tarring and maximum extension of boiler life. The thermostatic filling valve should be installed on the return line to the boiler or to fill storage vessels.

Technical data:

• max. operating pressure PN10
• medium temperature: 0°C to 110°C
• material: ductile cast iron

- The valve can be used either as a mixing or as a splitting valve, it contains a thermostatic cartridge that opens inlet A at the outlet mixed water temperature AB of the given °C. If the temperature in inlet A exceeds the nominal opening temperature by 10 °C, inlet B will close completely. It is recommended to use ball shut-off valves in the application to facilitate possible servicing.
