Safety Warning

Item Information

The A4A outlet family of regulators are compact, heavy duty, pilot operated, and have remarkable functionality. The regulator will gradually close when downstream pressure begins to rise above the setting and will gradually open when pressure begins to fall below the setting. The regulator cannot maintain set-for pressure if uncontrolled branch pipe lines feed into the main pipeline downstream of the regulator. The valve’s purpose is to modulate flow of refrigerant gas or liquid to maintain constant downstream pressure as set-for, despite load fluctuations.

Markets:
• Industrial Refrigeration
• Commercial Refrigeration

Features and Benefits:
• Pilot operated characterized Modulating Plug for precise control
• Suitable for all common refrigerants and oil
• 28bar (406psig) design pressure (MRP)
• Unique modular construction
• Flanges threaded or welded steel pipe and copper tube (copper not for ammonia)
• Interchangeable parts
• Easy to service
• Close coupled strainers, optional
• Many control variations are possible with the use of a few Modules and Kits
• Stainless Steel Diaphragm
• Chrome Plated Pilot Seat
• Manual Opening Stem

Application:
• Depending on the specific variation of this valve, the application may include, but is not limited to;   
• Compressor Motor overload prevention, Hot Gas Bypass Capacity Control, limiting refrigerant pressure in a liquid line, deep vacuum prevention in booster suction, Pressure Rise prevention in suction main, Hot Gas Defrost Control
