Parker Hannifin 470063 Suction Line Accumulator ODF - 1-3/8 VA611-11SRD

The Parker Hannifin 470063 is a vertical suction line accumulator designed to protect refrigeration and HVAC compressors from liquid refrigerant flooding. This critical component features 1-3/8" ODF (Outside Diameter Flare) sweat connections for direct soldering into the suction line.

Key Features:

• Model VA611-11SRD with 1-3/8" ODF copper connections
• Internal U-tube design draws vapor refrigerant from the top of the vessel
• Metering orifice at the bottom returns oil and small amounts of liquid refrigerant to the compressor at controlled rates
• Vertical mounting orientation for optimal liquid/vapor separation
• Brass construction for durability and corrosion resistance
• Compatible with common refrigerants including R-22, R-134A, R-404A, R-407C, and R-410A

Suction line accumulators prevent compressor damage by trapping liquid refrigerant that may return through the suction line during system operation, defrost cycles, or startup conditions. The accumulator temporarily holds excess liquid while allowing only vapor refrigerant to reach the compressor, preventing slugging that can cause broken valves, damaged pistons, or bearing failure. This unit should be installed in the suction line as close as possible to the compressor in a vertical position for proper operation.
