Bipropellant Torque Motor Thruster Valves

Moog Torque Motor thruster valves have been in production for almost four decades. T/M thruster valves were originally developed for the original Galileo spacecraft and for Minuteman II and III engines. The T/M thruster valve has a normally closed configuration. Redundant upstream valves can have a normally closed or latch valve configuration. One command will control both fuel and ox propellant lines.
