2. Pyrotechnic valves - Wikipedia

   en.wikipedia.org/wiki/Pyrotechnic_valves

   Pyrotechnic valves have an extremely fast response time (time from the actuation signal reaching the device til the valve has closed/opened), often in the order of a few milliseconds. [ 1 ] Normally-closed pyro valves have a far lower leak rate than other valves, allowing them to hermetically seal propellant inside a tank to keep it from ...

Valves can be categorized into the following types, based on their operating mechanism: Ball valve, for on–off control without pressure drop. Ideal for quick shut-off, since a 90° turn completely ...

4. Ball valve - Wikipedia

   en.wikipedia.org/wiki/Ball_valve

   A ball valve is a flow control device which uses a hollow, perforated, and pivoting ball to control fluid flowing through it. It is open when the hole through the middle of the ball is in line with the flow inlet, and closed when it is pivoted 90 degrees by the valve handle, blocking the flow. [1]

   A propulsion system is also needed for spacecraft that perform momentum management maneuvers. Components of a conventional propulsion subsystem include fuel, tankage, valves, pipes, and thrusters. The thermal control system interfaces with the propulsion subsystem by monitoring the temperature of those components, and by preheating tanks and ...
