Self-reliance Temperature Regulator
Self-reliance Temperature Regulator
Features
ZZYP, ZZYM type self-reliance temperature regulator is mainly consists of control valve and thermostat, it is a kind of energy-saving product that without needing external energy and rely on medium temperature changes to adjust automatically. V230W01/02 self-reliance temperature regulator is mainly applicable to the corrosive gas, steam, water, oil, and other media heat exchanger automatic temperature control, it is widely used in urban heating, heating system and petrochemical, printing and dyeing, pharmacy, boiler, and other industrial departments. Shanghai Yihuan flow control equipment Co.,ltd produced regulator main parameters are: nominal pressure PN16, 40; nominal diameter 20-200mm; temperature adjusting range 0-250℃, and various varieties for choice
