Safety valves for rocket technology

The projects of the Wissenschaftliche Arbeitsgemeinschaft für Raketentechnik und Raumfahrt e. V. (WARR) aim to be the first student team in Europe to develop a hybrid rocket with a cryogenic engine. The students' task is to design a sounding rocket that combines technological excellence with safety and efficiency. The WARR Rocketry team is relying on safety valves from Goetze KG Armaturen to power the rocket and the test rig's fluid system.

The Series 492 safety valves protect various segments of the fluid system in the project, such as the tanks for ethanol and liquid oxygen (LOX). The GOX design of the 492 series results from the use of liquid oxygen, with which the valve has no contact, but with which the vaporisation of the LOX above the tank creates an oxygen atmosphere.

“The valves therefore ensure the safety and functionality of both the test stand and the 'Ex-4' rocket when using liquid propellant”, says Goetze. “This collaboration shows how high-quality components such as our safety valves can make a decisive difference in space technology.”
