الأسئلة الشائعة التي تهم مستخدمي طراز 80%
1. What size and pressure ratings should I select for a PTFE-lined wafer butterfly valve?
• Choose sizes from DN50–DN300 (2″–12″) to fit standard pipeline systems.
• Ensure the pressure rating PN10 / PN16 matches your system pressure.
• Verify actuator torque to prevent leakage or incomplete closure.
• Check manufacturer data for accurate pressure and flow compatibility.
2. Can the pneumatic cast iron wafer butterfly valve handle aggressive chemicals?
• The PTFE lining resists strong acids, alkalis, and solvents.
• Low-friction liner surface prevents buildup and ensures smooth flow.
• Wafer design allows easy sealing and installation in corrosive pipelines.
• Ideal for chemical, wastewater, and process industries.
3. How to select the right actuator for an air-operated wafer butterfly valve?
• Use ISO 5211 mounting to ensure direct actuator installation.
• Choose spring-return or double-acting type based on control needs.
• Confirm actuator torque exceeds valve operating torque.
• Match voltage options 24 V DC, 110 V AC, 220 V AC for automation systems.
4. What maintenance ensures long service life of a PTFE-lined butterfly valve?
• Inspect the PTFE liner regularly for cracks or deformation.
• Maintain correct flange alignment and torque during installation.
• Monitor torque variation to detect early seat or disc wear.
• Keep actuator parts clean and air supply stable.
