Parker Hannifin 470093 VA-35-6S 3/4" ODF Suction Line Accumulator

The Parker Hannifin 470093 is a high-quality suction line accumulator designed to protect refrigeration and air conditioning compressors from liquid refrigerant damage. This VA-35-6S model features 3/4 inch ODF (flare) connections and serves as a critical safeguard in HVAC systems, heat pumps, and commercial refrigeration applications.

Key Features:

• Solid copper connections for reliable, long-lasting performance
• U-tube design maximizes refrigerant flow while minimizing oil entrapment
• Inlet flow deflector guides refrigerant for smooth tangential flow and gradual expansion
• Strategically positioned U-tube entrance prevents unwanted liquid refrigerant from entering or damaging compressors
• Metering orifice matched to system capacity ensures optimum liquid refrigerant and oil flow to compressor
• Fittings and U-tube matched to accumulator holding capacity for minimum pressure drop and maximum refrigerant flow
• Replaces PA-3060-15-6

The suction line accumulator installs in the suction line just before the compressor and acts as a temporary storage vessel for liquid refrigerant that may return during system operation. Its internal U-tube design draws gaseous refrigerant from the top of the vessel while a precision metering orifice at the bottom returns oil and small amounts of liquid refrigerant to the compressor at a controlled rate, preventing liquid slugging and compressor damage.

Ideal for heat pump systems, truck refrigeration, air conditioning units, and any application where intermittent compressor operation or sudden liquid refrigerant return is possible. This accumulator provides essential protection against broken valves, damaged pistons, bearing washout, and other costly compressor failures.
