The thermometer built into the ball valve provides visual temperature control of the working medium in heating points, hot water inlets, boiler pipelines and other points of engineering systems. The thermometer is connected to the ball valve by a copper alloy sleeve, which allows the temperature to be measured with a minimum error. The instrument can be easily removed from the housing when required. The use of ball valves as control valves is not permitted.
