A PTFE lined ball valve is a valve that has a ball of stainless steel or other material that is covered with a PTFE (Polytetrafluoroethylene) layer. The PTFE lining ensures superior resistance to high temperatures, chemicals, and corrosion and thus such valves are well-suited for applications in industries like food processing, pharmaceutical, and chemical processing. PTFE lined ball valves & check valve guarantee leakproof performance and are very resilient, providing consistent control of fluid flow in extreme conditions.

Perfect for use in aggressive chemical environments.
Promotes smooth flow and minimizes material buildup.
Handles extreme conditions—up to 260°C and high pressure levels.
Delivers comparable performance at a significantly lower cost.
A PTFE lined ball valve is designed with a corrosion-resistant PTFE lining, ideal for controlling flow in highly corrosive environments like chemical plants, pharmaceuticals, and wastewater treatment systems.
These valves typically withstand temperatures up to 260°C and moderate to high pressures, offering reliable performance in demanding applications involving aggressive chemicals or high thermal conditions.
PTFE lined valves resist corrosion, reduce friction, and prevent contamination. They are cost-effective for handling aggressive chemicals, unlike exotic alloys that are more expensive and less adaptable.
They are widely used in chemical processing, pharmaceuticals, food and beverage, and water treatment industries where chemical resistance, cleanliness, and long service life are critical.
PTFE lined valves are not ideal for abrasive media, as the soft lining can wear down. Alternative materials or reinforcements are better suited for handling solid-laden or abrasive fluids.
We are the leading Manufacturer and Supplier of Grayson PTFE Lined Pipe, Fittings, Flanges, Spool and Valves in Midland, UK.
