Parker® 101721

Description

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.
