Description
This high-performance PVCu flanged butterfly valve is designed for reliable isolation and flow control across a wide range of industrial and commercial pipework systems. Manufactured from rigid unplasticised PVC (PVCu), it offers excellent resistance to corrosion and many commonly used process media, making it a robust alternative to traditional metal valves.
Suitable for operating temperatures from 5°C to 60°C, this butterfly valve is ideal for cold and mildly warm fluid systems in applications such as water treatment, chemical handling, process pipework and general services. Available in a choice of sizes from 75mm to 225mm, it integrates easily into new installations or retrofit projects using standard flanged connections.
Product Features
- Available in a wide range of nominal bore sizes: 75mm, 90mm, 110mm, 125mm, 140mm, 160mm, 200mm and 225mm.
- Manufactured from durable PVCu for excellent corrosion resistance and chemical compatibility.
- Flanged end connections for straightforward installation into existing pipework systems.
- Butterfly valve design for compact, low-weight flow control compared with traditional gate or globe valves.
- Operating temperature range from 5°C to 60°C for cold and mildly heated process lines.
- Quarter-turn operation for rapid opening and closing, suitable for manual or automated actuation (where compatible hardware is used).
- Designed for use in industrial, commercial and light process applications handling compatible liquids.
Key Features and Benefits
- Corrosion-resistant PVCu construction helps extend service life in environments where metal valves may degrade.
- Flanged configuration offers a secure, leak-resistant joint and simplifies removal for maintenance or system modifications.
- Compact butterfly design saves space and reduces overall installation weight, particularly in larger bore sizes.
- Wide size range from 75mm to 225mm supports consistent specification across small distribution lines and larger mains.
- Defined operating temperature range of 5°C to 60°C provides reliable performance in many water and general service applications.
- Low-maintenance design can help reduce downtime and servicing costs over the life of the system.

Frequently Asked Questions
Which valve size should I choose for my pipework?
Select the butterfly valve size that matches the nominal bore of your existing pipe and flange standard. For example, use a 110mm valve on a 110mm PVCu pipeline. Always confirm flange dimensions and drilling patterns to ensure full compatibility before installation.
Can this PVCu butterfly valve be used with hot liquids above 60°C?
No. This valve is designed for an operating temperature range of 5°C to 60°C. Using it above 60°C may reduce mechanical strength, compromise sealing performance and shorten service life. For hotter systems, a valve specifically rated for higher temperatures should be specified.
Is this valve suitable for all chemicals in an industrial process?
Not all chemicals are compatible with PVCu. While the material is resistant to many common process liquids, you must check the chemical compatibility of your specific medium, its concentration and operating temperature with PVCu before use. Consult a chemical resistance guide or your system designer if you are unsure.
