ZDLT Electric Diaphragm regulator temperature Valve

Such control value uses small,strong and high precision electric actuator with ON-OFF fuction or with 4-20mADC or 1-5v direct current signal to realize value's proportional action,which is suitable for the condition of corrosion resisting, high toxic pipeline, this electric lined single-seat control valve is the execution unit in automation instrument system; it consists of many spring film actuators/electric actuators and through-way fluorine-lined single-seat regulator. Installed on the medium pipeline and operated with other instrument to control parameters such as flow rate etc. Due to the wetted parts of valve are lined with fluorine plastic (PTFE, PFA, FEP), and the stem sealing adopts PTFE bellow and packing, it has better performance in corrosion resistance and sealing and its installation has better reliability. It’s suitable for any corrosive medium except for "molten alkali metals and fluorine element”. The lined control valves are widely used in petrochemical, electric power, metallurgy, pulp & paper and other industrial automation device.
