Steam Blow-off Valve

grabcad

This is a valve that is used to prevent high pressure chambers/tanks from blowing up. It uses an ordinary spring to optimize the pressure release. I uploaded all parts, so LEGO ON! :) The renders are not too artistic, but the main goal here is function. The model has several threaded parts which are not displayed on the assembly. (sorry about that) All in all I think its an important little tool.
