Gas Butterfly Valves: Streamlined Control for Efficient Gas Flow

Published: 17 May 2023

Gas butterfly valves are quarter-turn valves that employ a disc-shaped closure mechanism to regulate the flow of gases. The valve's disc, positioned perpendicular to the flow, rotates within the valve body. When the disc is fully open, it allows unobstructed gas flow, while closing the disc restricts or shuts off the flow entirely. The simple and robust design of gas butterfly valves makes them suitable for a wide range of applications.
