Waits Valve is the main manufacturer and supplier of Level PTFE Lined Ball Valve. With chemical resistance, reliable sealing, smooth operation and durable design, Level PTFE Lined Ball Valve can achieve precise flow control in harsh environments! Waits Valve is an expert in valves with stable quality. For 20 years, we have been committed to manufacturing durable general purpose valves.
When you need to control the opening and closing of highly corrosive media, I believe you will use our Waits Valve durable Level PTFE Lined Ball Valve. These valves are also equipped with anti blowout stem assemblies to prevent stem blowout even without top gear assemblies. Widely used in industries such as petroleum, chemical, printing and dyeing, pesticide manufacturing, acid and alkali production, it is the choice of corrosion resistant valves. These valves provide a variety of installation methods (flange, BW, NPT, etc.), and can be customized with corrosion-resistant materials (such as PTFE-lined stainless steel), explosion-proof design or fire-proof structure to meet the safety control requirements in different environments.

Product Maintenance Notes
1.Avoid forcing the handwheel (especially when jammed) to prevent damage to valve body or sealing surfaces.
2.Regularly check for looseness at the handwheel stem connection.
3.Prohibit operation under excessive temperature/pressure (fluoroplastics deform at high temperatures).
4.Inspect lining for damage (e.g., bubbles, cracks) during shutdowns and replace promptly.
Product Advantages
1.Manual open/close without tools.
2.Simple structure, ideal for budget-sensitive scenarios.
3.No wear prone transmission parts, minimal repairs needed.
