Semi-automatic manifold used in laboratory gas management, centralized gas supply, test instruments, petrochemical industry, semiconductor industry, etc. Semi-automatic manifolds are used to adjust and control the uninterrupted gas supply of the middle and small flow compressed gas cylinder manifolds. When the gas on the priority supply side is depleted, the pressure drops, automatically switching to the standby supply side.
Select the direction of the handle (left or right) to set the priority supply side and backup supply side. By adjusting the output pressure reducer, the output pressure of the switching device can be set.
