A42AV400A7X00B3XYXSN Refrigerating Specialties (RS) 1-5/8 A4AOS Basic Regulator with Modudaptor Range V, 120G, Strainer

The A4A inlet family of regulators are compact, heavy duty, pilot operated, and have remarkable functionality. They sue upstream pressure for the opening force and require a minimum 0.14bar (2psig) pressure drop to open. These valves are normally ordered with close coupled upstream strainers to prevent the entrance of foreign materials into the valve and rest of system. The valve's purpose is to modulate flow of refrigerant gas or liquid to maintain constant upstream pressure as set-for, despite load fluctuations.Features and Benefits:Pilot operated characterized Modulating Plug for precise controlSuitable for all common refrigerants and oil27.6bar (400psig) design pressure (MRP)Flanges threaded or welded steel pipe and copper tube (copper not for ammonia)Interchangeable partsEasy to serviceClose coupled strainers, optionalMany control variations are possible with the use of a few Modules and KitsStainless Steel DiaphragmChrome Plated Pilot SeatManual Opening Stem
