The new concept for hydrant pit valves – pilotless (64231 with lanyard override shown) includes ductile iron inlet housing, two-piece aluminum upper housing with replaceable stainless steel outlet with dust cap & high capacity pressure equalizing valve. The Carter Model 60554 Hydrant pit Valve is a family of valves that includes lanyard, air or dual air/lanyard operated pilot valves, with the latter available with a defueling option. The latest series of the 60554 Hydrant Pit valves meet all the requirements of the 3rd Edition of API/IP 1584, including the new breakaway and strength requirements. The basic hydrant pit valve consists of three basic parts, lower valve assembly, upper valve assembly (or API outlet adapter) and either the new pilotless (patent pending) (Option X) valve or the standard valve with a pilot valve. The lower valve assembly contains an isolation valve which will allow the removal and servicing of the upper valve assembly and the pilot valve assembly while the pit valve is still installed. (See service manual SM60554 for proper instructions). The upper portion of all versions of the 60554 are now furnished with a replaceable part that contains the interface with the hydrant coupler. This minimizes replacement parts expense and allows the easy replacement of the outlet wearing surfaces. An option is also available to conform the valve to the IP Standard by adding the appropriate 6-inch inlet flange adapter. The outlet conforms to the API Bulletin 1584 Standard. The Model 60554 Hydrant Pit Valve is designed to minimize the propagation of surge pressure shocks into the upstream piping system during closure of the valve.
Dual Air and Lanyard Operated Pilot Valve for deadman control and manual on/off control for use in small pit (12 or 13” dia.) only. Uni-directional only unless combined with option J.
Dual Air and Lanyard Operated Pilot Valve for deadman control and manual on/off control for use in standard pits (18” or larger). Uni-directional only unless combined with option J.
Same as 60554D except material of outer housing is ductile iron per ASTM A395 (Special Order only). The Upper and Lower Valve Assemblies are fastened together with 15 metric threaded screws instead of the normal 8 UNF threaded screws (replaced 60554-2D).
Valve with the major operating part of the pilot valve contained on a quick disconnect half located on the hydrant servicer hose, can be used as air/fuel pressure operation or with lanyard backup (patent pending).
