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 Model 60554 Hydrant Pit Valves meet all the requirements of the 3rd edition of API/IP Bulletin 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 standard pilot valve or one of three patented pilot valve actuators (Model 64230, Model 64231 and Model 64280), available as Option X.
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.
The upper portion of all versions of Model 60554 are now furnished with a replaceable part that contains the interface with the hydrant coupler. This minimizes replacement parts expense and allows for easy replacement of the outlet wearing surfaces.
