Product Description
Our PTFE-lined check valve with sight glass is a backflow prevention valve specifically designed for highly corrosive media and high-cleanliness applications. The valve body is lined with polytetrafluoroethylene (PTFE), which has excellent corrosion resistance and effectively prevents corrosion of the metal by acids, alkalis, and salts. The sight glass design allows operators to clearly observe the flow of the medium during operation, ensuring the safety and stability of the system.
Our PTFE-lined check valve with sight glass is widely used in chemical, pharmaceutical, water treatment, and other industries involving corrosive fluids, providing a safe and reliable backflow prevention solution.
Tests & Standards
- Pressure and air tightness tests comply with EN 12266-1 (2012-06), Leakage Class D.
- Valve inspection and testing comply with API 598.
- The lining undergoes a 20kV spark test to ensure it is free of defects and leaks.
