Summary
The Rafael Ltd Propulsion System Latch valves is a latching valve that is magnetically latched, and solenoid operated with flight heritage. The dual-coil latch valve uses a pulse-energized electric input signal on the appropriate coil to change the position of the plunger.
The single-seat permanent magnet provides the necessary magnetic latching force to maintain the position of the plunger and the input signal is no longer required.
The valve features a 15-micron absolute integrated filter. Limit switch for connect/disconnect capability is done through a reed-switch, a magnetic type which also provides the valve position indication.
The inlet and outlet interfaces are MS 33656G-4 or 0.25'' tubes. The storage lifetime is 7 years and flight lifetime is 8 years.
