526 LC Series Switchover

Brass pressure differential liquid primary, high-pressure reserve switchover for high purity gas applications
526C01A-01-001 shown
Brass pressure differential liquid primary, high-pressure reserve switchover for high purity gas applications

The 526 LC Series Switchover System with inlet pressure transducers is designed to provide a continuous supply of high purity gas from a primary cryogenic source and backup high pressure cylinders. The system comes with options for flexible hoses or manifold connectors for the high pressure side for use with multiple cylinders. The 526 LC Series pressure differential switchover, when configured with manifold connectors, is suitable for use with the 52B (brass), 52C (chrome-plated brass), and 52S (stainless steel) Series maniflex manifold header system. Options for the 526 LC Series switchovers include purge valves to allow purging after cylinder changeover and the CONCOA Altos 2™ alarm for remote cylinder pressure monitoring. For complete flexibility in supply mode including optimization of source selection, CONCOA recommends the IntelliSwitch gas management system.
