Model S7000 HP Changeover Manifold

Acme Model S7000 Automatic Changeover Manifolds are designed to eliminate system downtime by ensuring uninterrupted gas flow from two banks of compressed gas cylinders. Model S7000 manifolds are identical in function and performance to Model S9000 manifolds, however, they are not enclosed, but rather mounted to a steel panel.

Model S7000 manifolds are a more cost effective option for users who desire the performance features of the S9000 manifolds, but do not require an enclosed unit.

System Design

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 cylinder bank can be discharged at a time. The unit s line regulator provides downstream adjustment for final pressure delivery.

System Operations

Once cylinders have been installed, the changeover manifold will first accept flow from the pre-determined primary bank. The S7000’s 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 cylinder bank, the operator simply turns the control knob to switch priority.
