Preguntas frecuentes que interesan a los usuarios del 80%
1. What corrosive media can a Lined Control Valve safely handle in chemical process systems?
• The Lined Control Valve is ideal for corrosive fluid regulation in chemical manufacturing and acid-resistant flow systems, using PTFE or PFA lining to block acid and alkali attack.
• Its fluoropolymer-lined body resists hydrochloric acid, sulfuric acid, caustic soda, and other aggressive chemicals.
• This corrosion-proof control valve prevents metal contamination and leakage.
• Widely used in chemical dosing, chlor-alkali, and pharmaceutical plants requiring zero leakage.
2. How does a Lined Control Valve improve flow accuracy and process stability?
• The fluorine-lined control valve uses a high-precision pneumatic actuator and positioner for responsive flow adjustment.
• Its smooth PTFE surface minimizes turbulence and pressure loss in industrial automation systems.
• Adjustable flow characteristics ensure precise control in acidic or solvent pipelines.
• Maintains consistent output and stable operation in chemical process control.
3. What maintenance advantages does a PTFE-Lined Control Valve offer?
• The lined regulating valve has a modular design for quick service and reduced downtime.
• The non-stick lining prevents residue buildup, keeping the flow path clean.
• Lightweight structure simplifies actuator alignment and replacement.
• Long service life lowers maintenance costs in wastewater and chemical systems.
4. What are the pressure and temperature limits of a Fluorine-Lined Control Valve?
• PTFE/PFA-lined valves operate from –20 °C to +180 °C and up to PN16 (150 PSI).
• The lined valve body maintains sealing under fluctuating pressure or temperature.
• Proper sizing ensures stable flow and prevents liner deformation.
• Suitable for acid-resistant control applications in harsh environments.
