ZZWPE type motorized temperature control regulating valve
Self-operated electric control temperature regulating valve (suitable for large caliber and heat-conducting oil control), which only needs ordinary 220V power supply, uses the energy of the regulated medium to automatically regulate and control the temperature of steam, hot gas, hot oil and gas, and can also be used to prevent overheating or heat exchange. The valve is simple in structure, convenient to operate, wide in temperature regulation range, fast in response time, reliable in sealing performance, and can be adjusted at will during operation. 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 operating temperature range is from-20ºC to 350ºC, and the receiving signal is 0~10mA.DC or 4~20mA.DC to change the flow rate of the medium to keep the controlled process parameters at a given value, among which the single-seat adjustment type is suitable for small pressure difference and medium viscosity Sleeve adjustment type is suitable for occasions with large pressure difference. Main parts materials: valve body and valve cover: HT200, ZG230-450, ZG1Cr18Ni9Ti valve core: ZG1Cr18Ni9Ti, Stellar alloy surfacing reinforced polytetrafluoroethylene filler: polytetrafluoroethylene, flexible graphite push rod, bushing: 2Cr13 gasket: rubber asbestos board, 10, 1Cr18Ni9Ti asbestos wrapped gasket bellows: 1Cr18Ni9Ti
