Manual Butterfly Valves are essential flow control devices used in industrial and commercial piping systems to regulate or isolate fluid flow. At Concorde Valves & Automations, we provide a wide range of high-quality Manual Butterfly Valves engineered for durability, precision, and smooth operation. These valves are ideal for applications in water treatment, HVAC systems, chemical plants, and general industrial processes where reliable manual control is required.
What Are Manual Butterfly Valves?
A Manual Butterfly Valve is a quarter-turn valve that uses a disc mounted on a shaft to control fluid flow. By turning the lever or handwheel 90 degrees, the disc rotates to either allow the fluid to pass or block the flow completely. Its simple design allows for quick and efficient operation, low pressure drop, and easy installation in pipelines.
Manual Butterfly Valves are widely used for isolation and throttling applications where automated control is not necessary, offering a cost-effective solution with minimal maintenance requirements.
