Multi-channel manifold JW-200

316 stainless steelfor gasfor medical devices

Overview An Automatic Gas Switchover Manifold JW-200 provides uninterrupted gas supply by automatically switching between cylinder banks or sources when the primary supply is depleted. Intended for laboratories, industrial processes and medical or analytical applications requiring high‑purity gases. The assembly includes manifold body, pressure regulators, valves, sensors and optional purge/alarm or display modules.
