RAQ

What is a wafer butterfly valve? +

Wafer butterfly valve is installed between two pipe flanges and secured by flange bolts. It features a compact, lightweight design and is widely used for isolating or regulating fluid flow.

What materials are available for wafer butterfly valves? +

They are commonly available in ductile iron, cast iron, stainless steel, carbon steel and sometimes aluminium bronze, with seat options like EPDM, NBR, or PTFE depending on the application.

What are the advantages of wafer-style butterfly valves? +

The main advantages of wafer-style butterfly valves are their compact, lightweight construction, which reduces material and installation costs, easy sandwich mounting between flanges without extra hardware, and reliable bi-directional sealing for isolation or flow regulation in tight spaces.

What applications are these valves typically used in? +

They are widely used in water systems, HVAC, general industrial processes, and low to medium pressure applications.

Is this butterfly valve suitable for use on water? +

Yes, wafer butterfly valves are highly suitable for water applications. They are commonly used in water treatment, irrigation, cooling water systems, and distribution pipelines due to their corrosion-resistant lining options (such as EPDM or NBR), reliable shut-off, and low pressure drop.
