Parker Hannifin 102923 A82 Inlet Pressure Regulator 2-1/8" ODF 1-5/8" Port

The Parker Hannifin 102923 is an A82 series inlet pressure regulator designed for commercial and industrial refrigeration and air conditioning 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 Specifications:

• Port Size: 1-5/8 inches

• Pressure Range: 10" vacuum to 400 psig
• Model: A82 (inlet pressure regulator function)
• Manufacturer Part Number: 102923

Advanced Features:

• Dual spring design for wide range pressure set-points
• Pilot operated for close control at desired set-point
• Low pressure drop for efficient operation
• Long-life stainless steel diaphragms with no bellows to fail
• All service accessible from the top
• Sweat-in-place installation without disassembly
• Manual opening feature included
• Furnished with access fitting

As an inlet pressure regulator, this valve opens when inlet pressure increases marginally above the set-point to increase flow and reduce inlet pressure, then closes as inlet pressure tends to drop, continuously adjusting flow area in response to operating conditions. It is suitable for a wide variety of control functions on industrial, commercial and air conditioning systems.

This regulator is ideal for evaporator pressure control, crankcase pressure regulation, and other applications requiring precise inlet pressure management in refrigeration systems. The modular design allows for easy servicing and maintenance without removing the valve from the line.
