What is PTFE Lined Butterfly Valve?

A PTFE Coated Butterfly Valve is a butterfly valve with a coating of a layer of PTFE (Polytetrafluoroethylene), FEP (Fluorinated Ethylene Propylene), or PFA (Perfluoroalkoxy) for greater chemical resistance. The lining protects the valve from corrosion, wear and chemicals under harsh conditions, making it appropriate for processing highly corrosive fluids in chemical processing, pharmaceuticals, and food processing industries. It offers consistent sealing and better durability, offering effective fluid control in harsh environments.

Frequently Asked Questions (FAQ)

What is a PTFE-lined butterfly valve?

A PTFE-lined butterfly valve is a type of valve with a disc that rotates to control fluid flow. It has a lining of PTFE (polytetrafluoroethylene), a high-performance plastic, which provides excellent resistance to chemicals, high temperatures, and corrosion.

What are the benefits of PTFE lining in butterfly valves?

PTFE lining offers superior chemical resistance, low friction, non-stick properties, and high-temperature tolerance, making the valve ideal for handling aggressive chemicals and ensuring long service life in corrosive environments

Where are PTFE-lined butterfly valves used?

These valves are commonly used in industries such as chemical processing, pharmaceuticals, food and beverage, water treatment, and oil and gas, particularly where fluids are aggressive or corrosive.

How does a PTFE-lined butterfly valve work?

The valve operates by rotating a disc within the pipe, with the PTFE lining providing a smooth, non-reactive surface that prevents corrosion and ensures the valve’s long-term performance in harsh environments.

How to maintain a PTFE lined butterfly valve?

Regularly inspect for wear, ensure proper alignment, and clean the valve to prevent residue buildup; PTFE’s non-stick nature helps reduce frequent maintenance needs.
