product description:
Self-electronically controlled temperature control valve (for larger caliber and HTF control), the biggest feature of the valve just an ordinary 220V power supply, energy use was transferred medium itself, directly to steam, hot air, hot oil and gas media, etc. implementation of automatic temperature regulation and control, also can be used to prevent overheating or heat exchange case, the valve structure is simple, easy to operate, wide choice of thermostat range, fast response time, reliable sealing performance, and can be adjusted freely in the operation, which is widely used hot water supply chemical, petroleum, food, textile, hotel and restaurant sectors such
Features:
This series of products nominal diameter from 20 to 200mm, nominal pressure has 1.0,1.6,4.0,6.4MPa, by the scope of the use of temperature -20 ℃ ~ 350 ℃, receiving signal is 0 ~ 10mA.DC or 4 ~ 20mA.DC to change medium flow is adjusted so that the controlled process parameters are kept at a given value, which is suitable for single-seat control pressure is small, medium viscosity or slightly larger particles of impurities occasions. Sleeve adjustment is suitable for a large pressure situations
