The 622 gas delivery system from CONCOA has a single-body design suited for start-up of 12 packs or liquid cylinders. The dome-loaded seat enables to system to transition into a point-of-use regulator for a bulk installation.
Used for nitrogen and oxygen assist gases from either cryogenic or high-pressure supply, the unit uses an integral pilot regulator with a stainless diaphragm and a brass bar stock body to maintain purity.
The unit features PTFE (for 3,000-PSIG inlet) or Kel-F® seat (for 4,500-PSIG inlet) and PTFE and Viton® internals for flexibility. Tubing and tube fittings are made of 316L stainless steel, and pressure gauges have a brass case and socket and a bronze Bourdon tube.
Maximum inlet pressure ranges from 600 to 4,500 PSIG, and temperatures from -40 to 140 degrees F. Maximum flow for nitrogen is 6,000 SCFH. Inlet and outlet connections are -in FPT, and weight is 12.5 lbs.
