Eaton’s Carter Model 60554 Hydrant Valve was developed to be used with a pressure control coupler.This revolutionary design removed many of the complicated control devices previously located in the pit, thereby reducing the cost of hydrant systems dramatically. Eaton has now introduced another concept that will reduce hydrant system maintenance costs even further. The relatively simple air and/ or manual pilots, standard on Model 60554 and Model 61654 Hydrant Valves, can be replaced by one of three patented pilot valve actuators (Model 64230, Model 64231 and Model 64280). These new pilot valve actuators have only a single moving piston and a quick disconnect device. The quick disconnect is similar to that now used on many hydrant valves to connect the air hose to the hydrant servicer. The entire hydrant-mounted pilot valve and air hose quick disconnect is replaced with the connector assembly part number 47576 and one of the three actuator types. Features • Reduces the complication on the hydrant valve — major part of the pilot is now on the hose on the servicer • Hydrant valve does not have to be removed if the pilot actuator fails • Actuator is rugged but lightweight — mainly stainless steel construction • Eliminates contamination of the pilot valve from ground water, jet fuel, and/or particles. Valve connector assembly is a sealed unit and does not require an open vent port. • All Model 60554 and Model 61654 hydrant valves can be retrofitted in the pit with the new pilot actuators • The actuator assembly can be operated with either air or fuel pressure. In fueling environments where some vehicles are set up with Eaton’s Carter Digital II System and others with a standard air operated system, this new concept works well, keeping the operation keyed to the vehicle. • Actuator is a push-on type connection. The sleeve on the actuator (on the hose) has to be retracted to disconnect. Carter® Air/Fuel Pilots - for Hydrant Valves Model 64230 Model 64231 Model 64280 Retrofitting Existing Model 60554 and Model 61654 air-operated hydrant valves can be retrofitted as follows: 1. Order one part number 47576 valve connector assembly (for air/fuel operation) kit for each hydrant valve 2. Order special tool part number T221790 (only a few per airport are needed) for use in installing assembly 3. Remove and discard the existing pilot valve and cage from the hydrant valve 4. Using the special tool, screw the stem assembly into the hydrant valve body 5. Once part number 47573 is seated and tightened, install part number 47574 connector assembly using the two bolts provided Retrofit hydrant servicers by ordering one each Model 64230, 64231 or 64280 Pilot Valve Actuator, as appropriate to your operation, for each servicer. Replace the existing disconnect on the hose to the hydrant valve with one of the three pilot valve actuators, as appropriate. It is recommended that at least one spare pilot valve actuator be ordered for each airport.
