Description Key Features • Meets all requirements of the EI and API 3rd Edition recommendations • The Meggitt (North Hollywood), Inc. Fuelling Product CCMY8500M3 Series EI 1584 3rd Edition Pit Coupler is a 4-inch unit designed for use with aviation kerosene and gasoline on airport hydrant systems and can be supplied with selectivity if required. • The coupler combines the Meggitt F251A 4-Inch API 3rd edition coupler with the CCMZ7300M3 pressure control elbow (not as pictured) • The coupler incorporates a manually operated poppet valve which is interlocked so that the valve cannot be opened if the coupler is not connected to an API Adapter. Conversely, the coupler cannot be disconnected when the poppet valve is in the open position • The fitting of the deadman pressure control valve allows a constant delivery pressure to be maintained at varying flow rates. The pressure control valve is of the direct pressure feedback type.

The valve works on the balanced diaphragm principle where the valve senses downstream pressure. The fuel pressure on one side of a diaphragm is balanced by air pressure on the other side keeping the valve in the required position. Trainz Station Not Working there. Incorporated within the valve is an emergency “deadman” shut off feature which may be used to start and stop product flow.

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.
