526 Series Switchover

The 526 Series Switchover operates by opposing pressure differential. It is designed to automatically switch from the primary side to the reserve side to deliver a continuous supply of high purity, non-corrosive gas. The system comes with either flexible hoses for use with two cylinders, or manifold connectors for use with the CONCOA 52 Series Maniflex Modular Manifold. Due to pressure differential considerations, an integral line regulator is available to maintain constant downstream pressure. Additional options for the 526 Series manifold switchover include purge valves to allow purging after cylinder changeover and outlet valves to allow isolation of the pipeline. For more flexibility in supply mode including optimization of high pressure, high purity gas applications, consider the CONCOA fully automatic, computer-controlled IntelliSwitch.
