How Do Gate Valves and Butterfly Valves Work?

Gate valves and butterfly valves are two commonly used valves in the fluid control industry. While they both serve the same purpose of controlling the flow of fluids, they have different designs and work in different ways. Gate valves work by using a gate or wedge that moves up and down to either open or close the valve. The gate is located between two seats that form a channel for the fluid to flow through. Butterfly valves, on the other hand, use a disc-shaped plate that rotates to regulate the flow of fluid. The disc is attached to a shaft, which is connected to a handle or actuator that rotates the disc to open or close the valve.
