It can be widely used in Industrial control system such as chemical industry, petroleum, metallurgy, medicine and electric power. It can be well applied to strong corrosive media such as acid and alkali

功能介绍 Function introduction

进口衬氟球阀(耐酸碱，耐腐蚀)电动衬氟球阀是由电动执行机构和O型衬氟球阀组成。阀体内腔及球芯均采用高压注塑工艺衬有耐腐蚀、耐老化的聚全氟乙炳烯，故具有可靠的耐腐蚀性和密封性。电动衬氟球阀主要用于对生产过程中酸碱等强腐蚀介质的调节或切断。电动执行机构内置伺服系统，无须另配伺服放大器，输入4-20mA信号及220VAC/380V电源即可控制运转 retz imported fluorine-lined ball valve (acid and alkali resistant, corrosion resistant) electric fluorine-lined ball valve is composed of electric actuator and O-type fluorine-lined ball valve. The inner cavity and ball core of the valve body are lined with corrosion resistant and aging resistant polyperfluoroethylene by high-pressure injection molding process, so they have reliable corrosion resistance and sealing. The electric fluorine lined ball valve is mainly used to regulate or cut off the strong corrosive media such as acid and alkali in the production process. The electric actuator is equipped with a built-in servo system, which can control the operation by inputting 4-20mA signal and 220VAC/380V power supply without additional servo amplifier
