Line Components

The A8 has a unique modular design that allows the commercial pressure regulator to be soldered into the line without disassembly, yet provides full access for disassembly, cleaning and servicing from the top only. Interchangeable capacity cartridges facilitate flow revisions should an undersized or oversized condition be created, while pilot adaptors can be changed out to add features or even change functions. Thus, retrofitting for additional evaporator capacity, heat reclaim, or hold back for hot gas defrost is simple and requires no pipe line revisions under most circumstances. These valves will modulate to maintain a pressure as set for in the field, in spite of fluctuations in load, changes in ambient, changes in available refrigerant flow paths, and other operating variances. Appropriately sized, these valves will modulate the flow of liquid or vapor, high side or low side in a wide variety of system arrangements used in industrial, commercial and air conditioning installations. Models are available in combinations of connection sizes, port sizes, functions and features as designated by the model code, for application in a wide variety of control functions on industrial, commercial and air conditioning systems.Three control functions are available:Inlet, Outlet, and Differential pressure control. Two control features can be added by incorporating pilot solenoids; either Electric Shut-Off(S) or Electric Bypass (B); also called Wide-Opening.The valves are an integrated assembly of four modules:1) A body, which contains no moving parts, but is ordered to suit a particular connection size;2) A capacity cartridge, which contains both piston and modulating plug, and defines the Port Size;3) A pilot adapter, which defines the valve function and onto which the Pilot Solenoids providing either the “S” or “B” feature are added as required;4) The bonnet, containing the Range Spring and adjustment screw, which mechanisms are set for the value of pressure which the valve is to maintain
