2 EATON Aerospace Group TF100-80E May 2013 Eaton’s 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. (See maintenance manual SM60554 for proper instructions). 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. An option is also available to bring the valve into compliance with IP standards by adding the appropriate 6-inch inlet flange adapter. The outlet conforms to the API Bulletin 1584 standard. 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. Features • Standard aluminum twopiece upper half standard, replaceable API outlet adapter of stainless steel per API Bulletin 1584. Ductile iron and stainless uppers with replaceable outlet optional. • Standard inlet flange mates with 4-inch 150 lb ANSI flange • Optional inlet flange mates with 6-inch 300 lb ANSI flange, making valve conform to the IP standard • Closing time is 2-5 seconds • New pilotless valve (Option X) reduces maintenance costs, lanyard, air or dual air/ lanyard operated pilot valve available (for small or large pit applications) • Servicing valve, standard, provides means to remove the upper valve assembly and pilot valve assembly with the unit still installed • Dual pilot adds true deadman backup to coupler, same as air-operated pilot. Hydrant valve is automatically closed at the end of the refueling operation. Lanyard operation can also be used with Option X valves. • All seals are field replaceable • Large pressure equalizing valve in the outlet is standard • Defueling capability optional with any air or dual air/ lanyard operated pilot • Stone guard optional with 6-inch inlet flange option • Ductile iron epoxy coated for corrosion protection • Main piston well-guided to minimize piston seal wear • 10- or 20-mesh screen options available Model Descriptions There are seven basic valves to which various modifications may be added by option letters as shown below. The six basic model numbers are as follows: • Model 60554D — Lanyard operated pilot valve for manual on/off control. Valve allows flow in the fueling direction only. • Model 60554E — Airoperated pilot valve for deadman control. Valve allows flow in the fueling direction only. • Model 60554F — Dual air and lanyard operated pilot valve for deadman control and manual on/off control for use in small pits only (12 or 13-inch dia.). Uni-directional only, unless combined with Option J. • Model 60554J — Air-operated pilot valve for deadman control with defuel control to allow flow of fuel in either fueling or defueling direction • Model 60554U – Dual air and lanyard operated pilot valve for deadman control and manual on/off control for use in standard pits (18-inch or larger). Uni-directional only, unless combined with Option J. • Model 60554-3D — Same as Model 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 Model 60554-2D). Two-piece upper half not available on this unit. • Model 60554X — Valve with the major operating part of the pilot valve contained on a quick disconnect actuator assembly located on the hydrant servicer hose. Can be used as air/fuel pressure operation (with Model 64230 Actuator Assembly) or with lanyard backup (with Model 64231 Actuator Assembly). Actuator assemblies ordered separately. Includes ductile iron inlet housing, two-piece aluminum upper housing with replaceable stainless steel outlet, dust cap and high capacity pressure equalizing valve. Design Concepts U.S. Pat.
