CONCOA 634 Series | Semi-Automatic Switchover | Two 6700 Regulators, 6000 SCFH
The CONCOA 634 Series is a semi-automatic switchover that works by opposing pressure differential between two heavy-duty 6700 Series regulators. Whichever regulator is set to the higher pressure takes priority, so changing banks means readjusting both outlet pressures. Point-of-use line or station regulators are still required, along with hose flashback arrestors for fuel gases.
The 634 Series is supplied configured to order, with outlet range, gauges, connections and options agreed at ordering; delivery ranges run from 0-15 PSIG (0-1 BAR) up to 0-200 PSIG (0-14 BAR).
