Latch Valves for Aircraft

Latch valves are solenoid valves that utilize a permanent magnet to maintain the valve poppet in both the open and closed position under pressure without electrical power.
Aircraft Latch Valves

Description

Latch valves are solenoid valves that offer bi-stable valve operation by utilizing a permanent magnet to maintain the valve poppet in both the open and closed position while under pressure. This eliminates the need for electrical power to hold the valve open or closed. Titanium and CRES body material with operating pressures to 10,000 PSIG are available, making them suitable for high pressure gases.

Application

Latch valves are found in aircraft cabin pressurization systems, and other systems where the desire to maintain last position without the need for electrical power exists.
