ZERO LEAK PNEUMATIC SOLENOID VALVES PRESERVE TANK PRESSURE IN MISSION CRITICAL AEROSPACE APPLICATIONS

Lee Products Ltd News and PR from Lee Products Ltd - Published 22 October 2021 THE CHALLENGE:
It is common for aerospace pneumatic systems to be supplied by a tank of compressed gas. In these systems, any leakage or excess flow from the tank results in a shorter system life or the need for a larger tank. As the gas is consumed, the pressure in the tank becomes depleted. A solenoid valve with zero leakage and a wide operating pressure range is needed to provide a barrier between the tank and the system. Various combinations of operating temperature range, material compatibility, power limitations, and life cycle may add complexity to the system requirements.

The 70-ohm solenoid coil requires less than 4 watts to open the valve
