Quarter-turn Valves

Quarter-turn valves are mechanical devices used to control the flow of fluids or gases in a pipeline by rotating the valve stem 90 degrees from the fully open to the fully closed position. These valves are commonly used in space and astronautical engineering applications due to their simple design, ease of operation, and reliability. Quarter-turn valves can be operated manually or automatically using an actuator, and they come in a variety of materials and sizes to suit different applications. They are used in spacecraft propulsion systems, life support systems, and other critical systems where precise control of fluid or gas flow is essential.
