D series filler valves are of heavy-duty construction throughout for rapid filling of ASME tanks or trucks. Thick-walled bodies, formed seat retainers and generous wrenching flats minimize damage to internal parts. Types D138 and D139 offer single back check valves for use with either a supplementary G Series back check valve or a manual shutoff valve. Types D140 and D141 provide a two-piece design with both an upper and lower back check.
