Instructions for use:
The valve has a large feature of only an ordinary 220V power supply, using the energy of the adjusted medium itself, directly to automatically adjust and control the temperature of steam, hot gas, hot oil and gas and other media, and can also be used to prevent overheating or heat exchange occasions , hotels and restaurants and other departments of hot water supply.
Product features:
The nominal diameter of this series of products is from 20 to 200mm, the nominal pressure is 1.0, 1.6, 4.0, 6.4MPa, the temperature range is -20°C~350°C, and the acceptance signal is 0~10mA.DC or 4~20mA.DC to change the flow rate of the regulated medium, so that the controlled process parameters are kept at the given value, of which the single-seat regulating type is suitable for occasions with small pressure difference, large medium viscosity or slightly particle impurities. The sleeve adjustment type is suitable for large pressure differentials.
