Lined valve

The electric fluorine lined regulating valve consists of an electric actuator and a fluorine lined regulating valve body. It receives 4-20mA analog signals from the controller to control the opening of the valve, thereby achieving the purpose of adjusting parameters such as flow rate and pressure of the pipeline medium.电动衬氟调节阀‌It is an automated valve designed for precise flow control of highly corrosive media, widely used in acid, alkali, solvent, and high-purity media transportation systems in industries such as chemical, pharmaceutical, and environmental protection. Its core design combines electric actuators with fluorine lined valve bodies, achieving continuous control of flow, pressure, or temperature through intelligent adjustment of valve core opening. It has corrosion resistance, high sealing, and high-precision adjustment capabilities, meeting the automation process requirements under complex working conditions.

‌结构设计‌

• ‌衬氟工艺‌The valve body, valve core, and inner cavity surface are lined with polytetrafluoroethylene (PTFE) or modified fluoroplastics (such as PFA, FEP) as a whole, effectively isolating the medium from the metal substrate, and withstanding strong acids (sulfuric acid, hydrochloric acid, nitric acid), strong alkalis, organic solvents, and high temperature media (-50 ℃~180 ℃). Some reinforced linings can be extended to 200 ℃.
• ‌电动执行器‌Configure high-precision servo motors and intelligent control modules to receive 4-20mA or pulse signals, achieve stepless adjustment of valve opening, support remote control, automatic feedback, and fault diagnosis functions, and adapt to industrial automation systems such as DCS and PLC.
• ‌阀体结构‌Direct or angular flow channel design, with plunger type, V-shaped opening or sleeve structure for the valve core, and optional linear or equal percentage flow characteristics to meet different adjustment needs.

‌核心优势‌

1. ‌精准调控‌The positioning accuracy of the electric actuator reaches ± 0.5%, with fast response speed. The opening can be adjusted in real time according to process parameters to ensure the stability and repeatability of flow control.
2. ‌超强耐腐蚀‌Fluoroplastic lining almost resists all chemical corrosion, avoiding the risk of leakage caused by medium erosion of metal valve bodies and extending their service life.
3. ‌零泄漏密封‌The valve seat and valve core adopt PTFE soft seal or metal+fluoroplastic composite sealing structure, with a sealing grade of ANSI VI, suitable for toxic and high-risk media.
4. ‌智能集成‌Supports communication protocols such as Modbus and HART, providing real-time feedback on valve position, torque, and fault signals for system monitoring and maintenance.

‌应用场景‌

• ‌化工流程‌Feeding control, pH adjustment, and proportioning system for reaction vessels containing corrosive media such as sulfuric acid and hydrochloric acid.
• ‌环保工程‌Adjustment of dosing flow rate for acidic and alkaline liquids in wastewater treatment.
• ‌制药与食品‌Accurate measurement and transportation of drugs and solvents in high-purity pipelines.
• ‌能源领域‌Control of boiler feedwater or cooling system for high-temperature acid-base media.

‌技术参数‌

• ‌公称通径‌: DN15~DN300 (customized up to DN400).
• ‌压力等级‌PN6~PN25 (high-voltage type supports PN40).
• ‌连接方式‌Flange (GB/HG/ANSI standard), threaded or clamp type.
• ‌可选功能‌Explosion proof motor, manual wheel, limit switch, temperature/pressure transmitter integrated.

The electric fluorine lined regulating valve, with "corrosion resistance+intelligent regulation" as its core, provides a safe, reliable, and efficient solution for corrosive media processes through the combination of high-precision electric control and fluoroplastic anti-corrosion technology. It significantly improves the level of production automation and process stability, and is suitable for long-term continuous operation under harsh working conditions.

The difference between corrosion-resistant electric fluorine lined regulating valves and other ordinary electric regulating valves lies in the valve body. Some pipelines transport highly corrosive media such as sulfuric acid and aqua regia. Due to its strong corrosiveness, ordinary metal regulating valves cannot be used for this purpose. A working state. The inner wall and internal components of the electric fluorine lined regulating valve that come into contact with the fluid are all produced using high-pressure injection molding technology. The inner lining is made of corrosion-resistant and aging resistant polytetrafluoroethylene (F46) and sealed with polytetrafluoroethylene bellows Solved the working condition where metal valves cannot be used in highly corrosive media. Widely used in pipelines with highly corrosive media.
