Valve
In space and astronautical engineering, a valve is a device that controls the flow of fluids or gases in a spacecraft's propulsion system, life support system, or other critical systems. Valves are essential components in spacecraft as they regulate the flow of propellants, coolants, and other fluids that are necessary for the proper functioning of the spacecraft. Valves can be manually operated or automated, and they come in various types such as ball valves, gate valves, globe valves, and butterfly valves. The selection of the valve type depends on the specific application and the fluid or gas that needs to be controlled. Valves are designed to withstand the harsh conditions of space, including extreme temperatures, radiation, and vacuum. They are also tested rigorously to ensure their reliability and durability in space missions.
