LINED VALVES

A lined valve is a widely used device in fluid control systems designed for regulating the flow of liquids or gases through a pipe while offering exceptional protection against corrosion and chemical reactions. It operates by incorporating a durable lining material, such as PTFE or PFA, within the valve body, ensuring the fluid remains isolated from the valve's structural components. Lined valves are ideal for applications where aggressive chemicals or abrasive fluids are involved, providing reliable flow control and long-lasting performance.

Lined valves are a crucial component in many systems due to their resistance to harsh media and versatility, serving as an optimal solution for controlling flow in pipelines. Commonly found in industries such as chemical processing, pharmaceuticals, water treatment, and food production, lined valves are essential for managing both small and large volumes of fluid securely and safely.

PR-FECT VALVES manufactures lined valves in a wide range of sizes, materials, and pressure ratings, ensuring compatibility with diverse industrial applications while offering advanced technical features such as precision-machined components, high-quality lining materials, and corrosion-resistant coatings for enhanced performance and durability.
