Manual Butterfly Valves: Purpose, Specifications, and Applications
Fluid control systems are expected to deliver top performance while maintaining simplicity, reliability, and efficiency. Manual butterfly valves meet these needs by offering a compact and cost-effective solution for regulating or isolating the flow of liquids and gases. Commonly found in industrial, commercial, and municipal systems, these valves are valued for their ease of operation and minimal maintenance requirements. Let’s explore more about manual butterfly valve s? A manual butterfly valve is a quarter-turn valve that uses a circular disc mounted on a rotating shaft to control flow. When the handle or lever is turned 90 degrees, the disc either aligns with the flow to allow passage or rotates perpendicular to block it. Because the operation is manual, no electrical or pneumatic actuator is required. Hence, the valve is suitable for straightforward flow control applications. Purpose of manual butterfly valves These valves are used to start, stop, or regulate the fl...
