Spacecraft Propulsion Components
Isolation Latch and Solenoid Valves
Latching and Normally Closed Solenoid Isolation Valves
These valve designs have been used in various space propulsion and operational systems in support of planetary and GEO satellite applications
Dual Line Isolation Latch Valves
This valve design utilizes a single torque motor and command signal to control two separate, hermetically sealed pressurant or propellent lines.
Single Line Isolation Latch Valves
These valves can be used for controlling propellants and pressurization gasses. The latch valves are bi-stable, and will stay in the last (open/closed) commanded position.
Thruster Valves
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.
Bipropellant Solenoid Thruster Valves
Moog's Bi-propellant Solenoid Thruster Valves are normally closed, single seat or series redundant seat configurations supporting thrusters up to 120N.
Monopropellant Solenoid Thruster Valves
Moog offers several different solenoid thruster valves supporting monopropellant propulsion applications from 1 N to greater than 700 N. These are available in single seat or series redundant seat configurations.
Regulators and Flow Control Valves
Electric Propulsion Proportional Flow Control Valve (PFCV)
The 51E339 Proportional Flow Control Valve (PFCV) is an all welded, normallyclosed, solenloid-type valve that can provide outlet flow control or pressure regulation in proportion to the input current.
Helium Pressure Regulator
This Moog pressure regulator is a series-redundant unit designed to provide stable tank pressure for propellant in a spacecraft propulsion system.
Electric Propulsion Mechanical Regulators
Moog offers single stage and two stage mechanical regulators in support of electric propulsion systems.
Bang Bang Regulator
Moog’s Bang Bang regulators are normally closed, series redundant solenoid valves that control a precise downstream pressure level over a large range of inlet pressures.
Service Valves
Fill and Drain Service Valves
These mechanically operated valves are opened/ closed by rotating an actuation nut. With a standard AN-style ground connection.
Fluid Transfer Couplings
Fluid Transfer Coupling (FTC)
The Moog Fluid Transfer Coupling (FTC) Is a stainless steel, two piece design using passive and active halves to secure fluid connection and sealing. Connection of the two halves will open the flow path after the sealing engagement is established.
Rolling Metal Diaphragm Tanks
Rolling Metal Diaphragm Tanks
Moog’s rolling diaphragm tanks are fabricated from commercially available aluminum alloys providing a low-cost short leadtime alternative to titanium propellant tanks. The tanks are easily sized to meet customer specifications and are individually designed to meet pressure, temperature, and flow requirements.
