R 12 VU B. Vacuum regulator with external leakage G 1/2"

Application:
With a preset vacuum level this valve breathes the atmospheric air and prevents the vacuum level from exceeding beyond the desired vacuum value. It is used to adjust a vacuum system with the same operating vacuum. The setting is done using a fine thread of the valve and the mechanical opening due to the spring load.
