Series HT - Ball valve for high temperatures

Products >> Floating ball valves

Application

Ball valve is isolating valve designed to fully open or close the service fluid flow. It is not designed to be used for throttling or regulating purposes. For temperatures up to +500 °C (for temperatures above +400 °C for non-oxidizing fluids only).

Suitable for water, steam, gas, oil, heat transfer fluids and other liquids and gases without mechanical impurities.

Approved for fluids in groups 1 (hazardous) and 2 according to 2014/68/EU.
