Plastic butterfly valves are a reliable and efficient alternative to metal valves in many applications. Made from PVC-U or high-temperature handling CPVC, they offer high chemical and corrosion resistance while being lightweight.

Our modular plastic butterfly valves can be easily integrated into any gas or liquid piping system due to their lower weight than metal ones. They are available with a wide variety of options for greater application versatility in polypropylene and special PTFE-lined valves that can be manufactured for high-purity applications.

Our control and shut-off valves have several butterfly designs that resist corrosion and ensure reliable application performance. These valves suit industrial water treatment, chemical process industry, chemical transportation, semiconductors, and power plants. You can choose from wafer-style and lug-style valves to meet your specific needs.

The PTFE butterfly valve is a plastic butterfly that plays a crucial role in various industries, particularly chemical processing, water treatment, and other industrial applications. It is known for its versatility and wide range of uses.

One of the key features of the PTFE butterfly valve is its body material. These valves are made from PTFE (polytetrafluoroethylene), a highly durable and chemically resistant material. They can withstand aggressive chemicals and corrosive environments. This makes them ideal for use in industries where chemical processing is involved.

Water treatment facilities also benefit greatly from the use of PTFE butterfly valves. These valves are resistant to scaling and can effectively control the flow of water without any leakage or contamination. They ensure smooth operation and longevity in demanding water treatment processes.

Its versatility makes it suitable for chemical processing plants, water treatment facilities, swimming pools, and numerous industrial applications requiring reliable fluid control mechanisms.

PTFE is a highly versatile material known for its exceptional chemical resistance and low coefficient of friction. It is often used in valve bodies and seals where aggressive chemicals or high temperatures are involved. PTFE can withstand a wide range of corrosive substances and offers excellent resistance to wear and tear.

On the other hand, PVC, or polyvinyl chloride, is a thermoplastic material commonly used in various industries. It has good corrosion resistance to many acids, alkalis, and salts. PVC is lightweight, cost-effective, and easy to work with, making it a popular choice for valve bodies in applications requiring moderate chemical resistance.

When selecting between PTFE and PVC for valve bodies or seal materials, it’s essential to consider the specific requirements of your application. Chemical compatibility, temperature range, pressure rating, and mechanical stress should be considered.
