619 Series Switchover

Pressure differential switchover for carbon dioxide laser resonator gases
6192001-01-001M shown

The 619 Series Switchover is an automatic pressure differential switchover that delivers a continuous supply of resonator gas without compromising purity. Low internal volume coupled with an optional inlet micro-purge virtually eliminates gas contamination. In addition, the stainless steel diaphragms and double-seal relief valve allow the 619 Switchover to achieve 1 x 10⁻⁸ scc/sec helium leak integrity. Optional remote alarm capability provides visual and audible notification of cylinder depletion for continuous system operation.
