Cobham introduces advanced Electric Propulsion Latch Valve
Cobham has introduced an advanced low pressure, multi-purpose Electric Propulsion Latch Valve, used to isolate pressure to satellites thrusters, to provide propulsion system designers greater flexibility with a wide range of flow that can be used in electric, cold gas, and chemical propulsion systems.
The coaxial valve operates at the typical, lower electric propulsion flow rates and can also flow to a much higher rate instantaneously with negligible pressure drop to address a wider spectrum of system design needs. The valve is exceptionally well suited for systems that require multiple propulsion systems, large electric propulsion thrusters or where a low pressure drop is required.
"This innovative, low pressure latch valve offers the electric propulsion community more capability, flexibility and economy in a single valve by performing more than one task and eliminating multiple component types. All this added capacity is provided in an exceptionally low weight and small envelope," said Eric Stellrecht, Product Director, Space, at Cobham Mission Systems. "We also have the unique capability to integrate this valve with our many other propulsion valve and tank products into mass and volume efficient assemblies to allow satellites to carry more payload. We can adjust our approach to fit any constraint, making it extremely flexible and customizable."
Cobham's electric propulsion products include low pressure and high pressure latch valves, mechanical regulators, miniature valves, and complete feed systems. In addition to satellite propulsion technologies, Cobham is also qualifying launch vehicle propulsion check and relief valves that will help send NASA further into deep space. These advanced technologies and other pneumatic products, including composite tanks, pyrotechnic valves, service valves, and solenoid valves, can be leveraged to meet any performance, budget or production quantity target.
