Parker Hannifin 100931 Flo-Con A9E Pressure Regulator 5/8" ODF

The Parker Hannifin 100931 is a Flo-Con A9E commercial pressure regulator designed for refrigeration systems requiring precise outlet pressure control. This pilot-operated regulator features a durable ductile iron body with brazed copper couplings and 5/8" ODF (sweat) connections on both inlet and outlet.

Key Features:

• 5/8" port size with 5/8" ODF brazed copper connections
• External equalizer (A9E) design for remote sensing applications
• Pressure Range A: 10" Hg vacuum to 120 psig (250mm Hg to 8.3 bar)
• Maximum rated pressure: 400 psig (27.5 bar)
• Flow coefficient (Cv): 1.0
• Operating temperature range: -50°F to 200°F (-45°C to 93°C)
• Pilot operated design provides close regulation and consistent performance
• Sweat end design allows soldering into line without disassembly
• Simple external adjustment for field setup
• UL listed for commercial refrigeration applications

This regulator is commonly used in hot gas bypass systems, condenser pressure control, and receiver pressure regulation in commercial refrigeration applications. The A9E external equalizer configuration allows pressure sensing at a remote location for enhanced system control.
