Abstract [en]

The normally closed valve which has a snap disk as an actuator will be used in space for passivation of propellant at the end of the mission. So currently it's been developed to match the requirements for operating in space. The current stage consists of design modifications and testing. Initially, a hermetically sealed one-shot valve was developed for the ExoMars Pasteur Payload. Later based on new requirements from ESA for the different objective of space mission the valve is modified with large tube diameters as inlet and outlet and whole valve body assembly made from stainless steel. The valve body is designed in a way so that 7 to 8 snap disk can be fitted as the number of a snap disk is obtained from certain test to determine the force value so that the spike can pierce the membrane and let the gas flow out. The force produced by the snap disk and force required to pierce the membrane was tested with certain test setups which were designed and manufactured. Thermal, stress and flow simulations are done in ANSYS and SolidWorks software.
