Butterfly valves are widely used in various industries for flow regulation and shut-off applications. Among the different types of butterfly valves, concentric butterfly valves stand out for their unique design and functionality. In this article, we will delve into what concentric butterfly valves are, their applications, and the advantages they offer.

Introduction to Butterfly ValvesButterfly valves are a pivotal component in the world of fluid control, offering a simple yet effective means to regulate the flow of materials.

A WRAS butterfly valve is a rotary valve that uses a disc as the closure member. WRAS butterfly valve are the most specified valve type for moderate-duty conditions in pipe sizes of two inches and larger. WRAS butterfly valve’s reduced weight, reliable bubble-tight shut-off, ease of operation and automation allowed them to displace gate valves in traditional applications.

WRAS butterfly valves are throttling valves that turn in a quarter-turn rotary motion. WRAS butterfly valves control the media flow in a system. The operators use these WRAS butterfly valves in different media and applications. When you operate a WRAS butterfly valve, it has a similar principle to a ball valve, that allows a fast shut off.

A butterfly valve is a quarter-turn rotary motion valve that is used to stop, regulate, and start the flow. Butterfly valves are a quick open type. A 90° rotation of the handle can completely close or open the butterfly valve.
