Model S7000L Changeover Manifold


Acme Model S7000L Automatic Liquid Cylinder Gas Changeover Manifolds are designed to eliminate system downtime by ensuring uninterrupted gas flow from two banks of cryogenic liquid gas cylinders. Model S7000L manifolds are identical in function and performance to Model SLIQ manifolds, however, they are panel mounted instead of enclosed, and do not contain status indicating lights. High and low pressure models are available.

Model S7000L manifolds are a more cost effective option for users who desire the performance features of the SLIQ manifolds, but do not require an enclosed unit or local indicating lights.

The changeover regulator incorporates two regulators within a common body and a single outlet. The design is such that with different set pressures, only one liquid cylinder bank can be discharged at a time. The units line regulator provides downstream adjustment for final pressure delivery. It features a Gas Saver Circuit, which contains check valves, set just below the cylinder relief valve setting to allow boil off on the reserve bank to be utilized, rather than wasted.

Once liquid cylinders have been installed, the changeover manifold will first accept flow from the pre-determined primary bank. The S7000Ls control knob points to the primary bank for easy identification. When the primary bank reaches a preset low pressure, the reserve bank automatically takes over. To replace the empty liquid cylinder bank, the operator simply turns the control knob to switch priority.
