A grooved butterfly valve is a type of pipeline control valve that regulates water flow—or shuts it off entirely—by rotating a disc (the butterfly plate) 90 degrees. The term "grooved" refers to the connection method at both ends, which utilizes mechanical couplings to clamp the valve in place; this allows for rapid installation and disassembly without the need for welding or extensive bolting, making it particularly well-suited for piping systems—such as fire protection and water supply/drainage networks—that require quick construction and ease of future maintenance. Designed to meet industry standards and offering excellent compatibility with mainstream coupling systems, these valves are widely used and highly favored in sectors including fire protection, HVAC, and industrial water distribution networks.
