FAQs

What is a CPVC butterfly valve?

A CPVC butterfly valve is a type of flow control device made from chlorinated polyvinyl chloride (CPVC) that regulates fluid flow using a rotating disc.

How does a CPVC butterfly valve work?

The valve operates by rotating a disc within the flow path. When the disc is aligned with the flow, the valve is open, allowing fluid to pass through. Rotating the disc perpendicular to the flow closes the valve, stopping the flow.

What are the main benefits of using CPVC over PVC in butterfly valves?

CPVC offers better temperature resistance and chemical durability compared to standard PVC, making it suitable for more demanding applications.

Are CPVC butterfly valves suitable for high-pressure applications?

While CPVC butterfly valves are robust, their pressure rating depends on the specific design and manufacturer specifications. They are generally used in low to moderate pressure applications.

Can CPVC butterfly valves be used for potable water applications?

Yes, CPVC butterfly valves are often used in potable water systems as they are safe and do not impart any taste or odor to the water.

What maintenance is required for CPVC butterfly valves?

Maintenance is minimal, typically involving periodic inspection and cleaning to ensure the valve remains free of deposits and operates smoothly.

How do CPVC butterfly valves compare to metal valves?

CPVC butterfly valves are lighter, easier to install, and more cost-effective than metal valves. However, metal valves may offer higher pressure ratings and are used in extreme conditions where plastic valves may not be suitable.
