Valve-Liq Load/Unld 3/4Fpt X 1 3/4 F Ac

Liquid Loading/Unloading Valve The ME450 liquid loading/unloading valve incorporates a double O-Ring seal on the stem assembly for leak free operation even under extreme temperature fluctuations. The double lead thread design of the stem allows adjustment from the closed position to full open in six full turns. The outlet boss on the side of the valve is tapped 1/4" FNPT and has a MEJ400 vent valve for your convenience. For use on tanks that do not have independent liquid withdrawal valves. NOTE: The ME450 does not require the use of adapters between the tank fill valve and the liquid loading/unloading valve. Do not use the loading/unloading valve for full time service. Extreme care must be used whenever liquid transfer of LPG is in progress. Only persons trained in the proper method of transfer should attempt this type of transfer. For further information on the methods of withdrawing liquid LPG from ASME containers, refer to the LPG Safety handbook, NPGA-0001, Bulletin #131-88 available from the NPGA.
