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 basic hydrant pit valve consists of three basic parts, lower valve assembly, upper valve assembly (or API outlet adapter) and the 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 under pressure. (See service manual SM60554 for proper instructions).

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 standard valve is provided with a new 2-piece upper adapter assembly with a replaceable stainless steel API connecting ring.

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.
