[2014-11-21]　Cryogenic double eccentric butterfly valve
Cryogenic butterfly valve is mainly used in liquefied natural gas and liquid nitrogen pipeline system, the control pipe opening and closing or regulating equipment. In view of the domestic market demand for cryogenic valve and its basically depends on the status of the imported products, developed a new type of cryogenic butterfly valve. Products adopted double eccentric structure and elastic metal seal

[2014-11-21]　The principle and characteristic of electric control valve
Electric control valve is based on the power the power, accept the unified standard electrical signal 0 to 10 ma (or 4-20 ma), servo amplifier amplification process, make the motor drive reducer running and produce axial thrust, thus regulating valve core shift accordingly reach the process flow, pressure, temperature, liquid level variables such as adjusting the intelligent control of the valve.br>

[2014-11-21]　Sichuan zigong valve factory about tungsten carbide wear-resisting ball valve
In polysilicon, coal chemical industry, power plant ash, mud and boiler slag discharge and other material in the pipeline, valve sealing parts not only by the seal parts of sliding friction and wear, and bear high temperature and high hardness, high speed impact gas-solid two phase mixture, and the high pressure fluid caused by flash and cavitation, resulting in damage, increase the valve failure. Therefore, powder conveying harsh working conditions, such as abrasion resistance became an important valve performance appraisal indicators.
