BRASS VALVES

BRASS VALVES

To service the new style valve, the two screws must be removed. Carefully remove the stem and spring. Using long nose pliers, pull the plug out. Clean the plug and core with a soft cloth. Inspect the plug and core. Look for scoring. If either piece is scored, the valve must be replaced. If there is no scoring, apply a thin coat of graphite- based gas valve grease to the plug.

Reinstall the plug into the core and rotate the plug in the core to distribute grease in the core. Remove plug; reapply another thin coat of grease to the plug. Reinstall plug into core (be sure that plug is in the off position when the stem is installed, with the flat side on the bottom). Reinstall the spring, washer and stem. Reinstall the collar with the screws (Diagram #16).

NOTE: The new-style valve has a spring that can be easily lost. It is a spring that is approximately half the size of a ballpoint pen spring. In addition to the spring there is a washer, a metal collar and two small screws. All pieces must be reassembled onto the valve.
