Product Overview
The PTFE Lined Ball Check Valve is a non-return valve specifically engineered for handling highly corrosive, aggressive, and hazardous fluids. The internal PTFE lining provides exceptional chemical resistance while the ball-type design ensures smooth, clog-free operation with minimal pressure loss.
Unlike conventional metal check valves, this valve prevents direct contact between the process media and the metallic body. It is widely used in chemical, pharmaceutical, effluent treatment, acid transfer, and specialty process industries where zero leakage and long service life are critical.
Key Benefits of PTFE Lined Ball Check Valve
- Excellent resistance to acids, alkalis, solvents, and corrosive chemicals
- Ball-type mechanism ensures tight sealing and zero backflow
- PTFE lining eliminates corrosion, scaling, and contamination
- Low pressure drop compared to flap or swing check valves
- Maintenance-free design with long operational life
- Ideal for horizontal or vertical installation (flow dependent)
