The 619 Series is a semi-automatic pressure differential switchover that delivers a continuous supply of resonator gas without compromising purity. The brass barstock design offers low internal volume. This, coupled with the optional inlet micro-purge, eliminates gas contamination. In addition, the stainless diaphragms and double seal relief valve enable the 619 to achieve 1x10-9 he cc/sec leak integrity. This makes the 619 the right choice for laser applications requiring optimum beam mode quality.
