The Carter Model 61654 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 61654 Hydrant pit valves meet the latest 3rd edition of API Bulletin 1584 with regard to 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 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 SM61654 for proper instructions). The upper portion of all versions of the 61654 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. The 61654 family of valves is essentially identical to the 60554 series of valves except for the inlet flange which is designed to mate with a 6" ANSI 150 lb. flange rather than a 4" flange. The Model 61654 Hydrant Pit Valve is designed to minimize the propagation of surge pressure shocks into the upstream piping system during closure of the valve.
Two-piece aluminum/stainless steel API Adapter, Lanyard Operated Pilot Valve for manual on/off control. Valve allows flow in the fueling direction only. (Defueling possible if outlet pressure does not exceed 21 psig).
Two-piece aluminum/stainless steel API Adapter, Air Operated Pilot Valve for deadman control. Valve allows flow in the fueling direction only. (Defueling possible if outlet pressure does not exceed 21 psig).
Two-piece aluminum/stainless steel API Adapter Air Operated Pilot Valve for deadman control with defuel control to allow flow of fuel in either fueling or defueling direction.
Two-piece aluminum/stainless steel API Adapter, Dual Lanyard/Air Operated Pilot Valve. Valve allows flow in the fueling direction only. (Defueling possible if outlet pressure does not exceed 21 psig or can be combined with “J” for full flow defuel).
