Temperature regulator RTVA-70S-50
Temperature regulator RTVA-70S-50 are designed for automatic maintenance of the coolant temperature in the diesel engine cooling system. They consist of an autoregulator and a housing with an emergency manual control mechanism installed in it. Automatic maintenance of the temperature of the coolant in the diesel engine cooling system is carried out by changing the ratio of the flow rates of the liquid passing through the regulator and going to the bypass (past the refrigerator) and into the refrigerator. The principle of operation of the RTVA-70S-50 thermostat is based on a change in the vapor pressure of a liquid with a change in temperature, which is converted into valve movement. Medium to be controlled: cooling water with potassium dichromate additive or other low freezing liquids. РТВА-70С-50 technical characteristics Nominal bore diameter: 50 mm.
