Designed specifically for use with RegO 7572FC and 7580FC Chek-Lok® Excess Flow Valves. The adapter’s operating handle opens and closes the equalizing stem in these older style Check-Lok® valves. This adapter is designed to eliminate the need for gas to flow from the Chek-Lok® when the adapter is installed or removed. Assembly includes a full port ball valve and 1-3/4″ male ACME.
When connecting to the old style Chek-Loks liquid is released to atmosphere until a positive seal is achieved. With this assemble the internal valve is not opened until the handle is rotated down.
Tank valves added for demonstration value only.
