2 EATONAerospace Group TF100-111C May 2013 Eaton’s Carter product line includes a variety of inline and bypass control valves. Models 64503 and 64513 are the latest innovation in 3 and 4-inch bypass solenoidoperated control valves. They replace earlier Model 64133 3-inch and Model 64134 4-inch bypass valves. This type of valve is especially suited for tow cart operation or vehicles on which an air reference source is not available. These valves utilize the directoperating design concept with a control module added to the basic valve. The new control module gives the unit finer control and eliminates exterior tubing from the valve. This control valve is mounted to the main valve body with one bolt. Should the user decide to change an air controlled valve to electric operation, this can be accomplished by simply removing one bolt, taking off the air operated control module and replacing it with a solenoid control module. The control module is available with either 12 or 24 VDC operation. The valves described here have been used very successfully on solar panel powered systems. All adjustments are made on the module. Bleeding of air from the valve requires no tools and can be accomplished without loosening any of the line fittings. Fixed orifice screws in the module control opening and closing times. No venting or air pressure gauges are required with these new valves. A small integral regulator is incorporated within the module to control pressure in the system. When the solenoids are de-energized the valve goes wide open. The same control module is used on both the 3 and 4-inch solenoid operated bypass control valves. Most of the seals in the main body of the 3 and 4-inch valves are the same, thus minimizing the spares required for any type of maintenance. The control module incorporates a unique bleeder that requires no tools to facilitate bleeding. Features � No air reference pressure required � Standard 150 lb ANSI inlet and outlet flanges � Victaulic adapters available – use only on one end unless adequately braced � Bleeding and pressure control adjustment simple � No expensive servos to adjust � Spare parts kept to a minimum due to lack of complicated servos. Many parts are common to same size inline valves. � Many spare parts also common to Eaton’s hydrant couplers Design Concepts Electric/Solenoid Controlled Pressure Control Systems Schematic of a typical electric/solenoid pressure controlled refueler system
