Valves
In space and astronautical engineering, valves are mechanical devices used to control the flow of fluids or gases in a system. They are critical components in spacecraft propulsion systems, life support systems, and other systems that require precise control of fluid or gas flow. Valves can be operated manually or automatically, and they come in a variety of types, including ball valves, gate valves, globe valves, and butterfly valves. The selection of valve type depends on the specific application and the requirements for flow rate, pressure, and temperature. Valves must be designed to withstand the harsh conditions of space, including extreme temperatures, radiation, and vacuum. They must also be reliable and have a long lifespan, as maintenance and repair in space is difficult and expensive.
