Airborne Manufacturing Co. (Parker) Lot of 2 Airborne 2H3-19

Description

Up for sale is a matched pair lot of two (2) vintage Airborne Model 2H3-19 Vacuum Regulating Valves featuring integrated John W. Hobbs Corp internal vacuum micro-switches for low-suction cockpit annunciator panel warning lights.

These units were carefully uninstalled during an avionics panel tear-down and are offered together as rebuildable core parts, bench test mockups, or historical displays.

The specific production dates are explicitly encoded via the original Airborne serial numbers stamped on the faceplates:

• Valve 1 (Serial 10 B): Manufactured October 1976

FUNCTIONAL USE:

These valves are designed to maintain stable negative pressure across altitudes for critical pneumatic instruments like the Attitude Horizon and Directional Gyro (DG). They serve as direct cross-references for the popular Rapco RA2H3-19 and the OEM Piper 492-240 valve assemblies.
