The PTFE Coated Butterfly Valve is a type of valve coated with a special material called PTFE (polytetrafluoroethylene), also commonly known as Teflon. PTFE is characterized by its chemical resistance, low coefficient of friction, and high-temperature durability.

These valves operate on the basic principles of a standard butterfly valve, allowing flow when open and stopping flow when closed. The PTFE coating protects the inner parts of the valve from wear and chemical corrosion. PTFE Coated Butterfly Valves are widely used in chemical processes, the petrochemical industry, and applications involving acids and aggressive chemicals.

Additionally, the PTFE coating creates a smooth surface inside the valve, enabling more efficient fluid control. Due to these properties, PTFE Coated Butterfly Valves are preferred in industrial applications that require chemical resistance and low friction.

With their exceptional chemical resistance and low friction coefficients, PTFE Coated Butterfly Valves offer durable and reliable solutions in demanding industrial conditions. HG-Stahl Butterfly Valves provide maximum efficiency and durability, especially in processes that come into contact with abrasive and aggressive chemicals, making them ideal for various chemical and petrochemical applications.

PTFE Coated Butterfly Valves can be manually operated or delivered with pneumatic or electric actuators. These valves help optimize industrial processes by offering high performance and reliability.

The PTFE Coated Butterfly Valve stands out for its ability to provide excellent sealing even under high pressure. This feature ensures safe and efficient operation, particularly in high-pressure systems. Thanks to the inert nature of PTFE, these valves can also be used in the food and pharmaceutical industries, as there is no risk of chemical reactions. The quality of the PTFE coating on the valve is highly important, and with our German partner, we offer high-durability products to our valued customers.

At HG-Stahl, we design and manufacture butterfly valve products such as Concentric Butterfly Valves, Double-Offset Butterfly Valves, Triple-Offset Butterfly Valves, Wafer-Style Butterfly Valves, Lug-Style Butterfly Valves, Double-Flanged Butterfly Valves, and Butt-Weld Butterfly Valves.

An additional advantage of PTFE/PFA coated valves is their suitability for applications requiring high purity. Thanks to the inert nature of PTFE, the material used in the valve does not chemically interact with the fluid, making PTFE-coated valves an ideal choice, especially in the pharmaceutical, food, and biotechnology industries. HG-Stahl develops special designs tailored to customer needs, ensuring these valves meet stringent sterilization requirements. By optimizing the thickness of the PTFE coating, chemical resistance is enhanced, and long-term usage is achieved.
