Parker Hannifin 102942 A82B Inlet Pressure Regulator with Electric Bypass 1-5/8" ODF

The Parker Hannifin 102942 is an A82B series inlet pressure regulator with electric bypass (wide-opening) feature, designed for industrial, commercial, and air conditioning refrigeration systems. This ductile iron-bodied regulator features brazed copper couplings and modulates the flow of refrigerant vapor or liquid to maintain constant pressure at a control point, regardless of fluctuations in load or ambient conditions.

Key Features:

• Wide range pressure setting from 250mm Hg to 27.6 bar (10" vacuum to 400 psig)
• 1-5/8" ODF (outside diameter flare) connection size with 1-5/8" port size
• Electric bypass (B) feature provides wide-opening capability when solenoid is energized
• Opens on rise in inlet pressure above set point and closes when inlet pressure drops below set point
• Modular design with four integrated assemblies: body, capacity cartridge, pilot adapter, and bonnet
• Can be soldered into line without disassembly, with full access for servicing from top only
• Interchangeable capacity cartridges and pilot adapters allow field modifications

The A82B inlet pressure regulator is ideal for controlling evaporator pressure, preventing compressor overload, and managing pressure in multiplex refrigeration systems. Models are available in various combinations of connection sizes, port sizes, and functions for diverse control applications on refrigeration and air conditioning equipment.
