Wafer PTFE (Teflon) Butterfly Valve

Product Features and Applications

Structural Features

Multi-Standard Design

The multi-standard wafer butterfly valve is compatible with various standard pipe flange connections, such as ISO, ANSI, DIN, and JIS, making it suitable for different international standard piping systems. This enhances its installation flexibility and versatility.

PTFE Sealing

The sealing surfaces of the valve body and disc are typically made from polytetrafluoroethylene (PTFE) or other fluoroplastics. This material offers excellent corrosion resistance, high-temperature tolerance, and good anti-adhesion properties, ensuring long-term stable operation of the valve in corrosive media.

Wafer Connection

The valve is clamped between two pipe flanges using bolts, without the need for special connection components, making installation simple and especially suitable for applications with limited space.

Compact Structure

This valve features a compact structure, lightweight design, and easy operation, reducing the overall weight of the piping system and minimizing installation space requirements.

Performance Features

Excellent Corrosion Resistance

By using PTFE material for the sealing surface and lining, this butterfly valve effectively resists corrosion from acids, alkalis, salts, and other corrosive media, making it highly suitable for industries such as chemical processing and pharmaceuticals.

Excellent Sealing

The flexibility of PTFE material allows the valve to form a tight seal when closed, ensuring reliable sealing under both high and low-temperature conditions, effectively preventing leakage.

Easy Operation

The butterfly valve operates smoothly, allowing for quick opening and closing through manual, pneumatic, or electric actuators, making it suitable for applications requiring frequent operation.

Bidirectional Sealing

This valve is designed for bidirectional sealing, ensuring excellent sealing performance regardless of the flow direction of the medium, which enhances its flexibility in use.

Application Fields

Chemical Industry

Widely used in the chemical industry for the transportation and control of corrosive media, such as acids, alkalis, and salt solutions.

Pharmaceutical Industry

Suitable for fluid control systems in the pharmaceutical industry that require high cleanliness and corrosion resistance, such as the transportation of various pharmaceutical liquids.

Food Industry

In the food processing industry, it is used for controlling and transporting various fluids. The PTFE material meets food-grade standards, ensuring safety and no contamination.

Pulp and Paper Industry

In the pulp and paper production process, it is suitable for the transportation and flow control of corrosive chemicals, ensuring the stability of the production process.

Installation and Maintenance

Easy Installation

The wafer design allows the valve to be easily clamped between pipe flanges and secured with bolts, requiring no special tools, making installation quick and convenient.

Convenient Maintenance

With its simple structure, the valve’s sealing elements and disc are easy to replace, resulting in minimal routine maintenance and reduced downtime.

Regular Inspection

It is recommended to regularly inspect the condition of the PTFE sealing elements and promptly replace any worn or aged seals to ensure the long-term reliability of the valve.
