Valve in Tank Assembly

Eaton's Valve in Tank Assembly (VITA) propulsion feed system

Eaton (Cleveland, OH) announced that it successfully completed qualification testing for the aerospace industry’s first Valve in Tank Assembly (VITA) propulsion feed system.

As the first satellite electric propulsion solution that integrates valves inside the propellant tank, the VITA eliminates the need for a traditional feed system envelope, creating room for more payload.

The design of Eaton’s VITA eliminates the feed system envelope by integrating proportional flow valve technology into a housing that is then integrated into the neck of a lightweight composite propellant tank.

The initial configuration of the VITA solution has two redundant shut-off valves to support one thruster for increased reliability. The drop-in VITA design approach supports modular satellite configurations, making architectural changes easier.

Qualified in testing with xenon, this system has demonstrated to be fully compatible with krypton as well.

Interface Modules

The Dinkle International interface modules

Dinkle International (Missouri, TX) announced its complete line of interface modules, used to simplify and improve reliability of automation connections and signal conversions, in a compact form factor.

When creating automation systems using major PLC brands like Allen-Bradley, Keyence, Mitsubishi, Omron, Siemens, and more, designers have to connect an ever-increasing number of equipment signals to the I/O modules. These signals may be discrete (on/off at anywhere from 5 VDC up to 120 VAC), analog (usually 4-20mA or 0-10 VDC), or other specialized signaling levels.

Interface modules are available with popular industry-standard connectors like: IDC (14-pin, 20-pin, 26-pin, 30-pin, 34-pin, 40-pin); D-Sub (37-pin, 44-pin); MDR (50-pin, 68-pin, 100-pin); and terminal blocks.
