我厂在上海工业自动化仪表研究所的指导帮助下,自一九七五年开始试制 KDF 型蒸汽电磁阀和 SDF 型冷水电磁阀,经过近三年的试制和批量生产,在上海、北京及全国十多个省市的有关工业单位使用,证明该二种新型电磁阀性能可靠,维护简单,使用寿命长,已被广泛应用在石油化工、纺织、电镀、制药、橡胶、电影技术、冶金等工业部门。为统一标准型号,经一机部主管部门批准颁发新型号,将 KDF 型蒸汽电磁阀定名为ZCZ 型,SDF 型冷水电磁阀定名为 ZCS 型冷水电磁阀。上述二种用于不同介质的电磁阀,均由二大组件组成,即导阀与主阀。导阀为直接动作
I plant in Shanghai Industrial Automation Instrumentation Institute under the guidance of help, since 1975 trial production of KDF-type steam solenoid valve and SDF-type cold water solenoid valve, after nearly three years of trial production and mass production in Shanghai, Beijing and the whole country The use of relevant industrial units in more than 10 provinces and municipalities proves that the two new solenoid valves are reliable, easy to maintain and long in service life and have been widely used in petrochemical, textile, electroplating, pharmaceutical, rubber, film technology, metallurgy and other industries department. To unify the standard model, approved by a machine department issued a new model, the KDF-type steam solenoid valve named ZCZ type, SDF-type cold water solenoid valve named ZCS-type cold water solenoid valve. The above two kinds of solenoid valves for different media, are composed of two major components, namely the pilot valve and the main valve. Pilot valve for direct action
