Parker CCJW Adjustable Expansion Valve R-134A 2-3 Ton

SKU CH-6PYT-8PS0N

Adjustable thermostatic expansion valve for R-134a systems rated at 2-3 tons with 3/8 in. inlet and 1/2 in. outlet flare connections

  • Product typeAdjustable
  • Adjustable valve controls refrigerant flow precisely for 2-3 ton R-134A systems
  • Externally adjustable design allows fine-tuning without system shutdown
  • Wide operating range from -40 to 60 maintains accuracy across load variations
  • Minimises hunting, flood-back and coil starving for stable evaporator performance
  • Includes sensing bulb mounting clamp for secure installation

Parker CCJW Adjustable Expansion Valve

The Parker CCJW is an adjustable thermostatic expansion valve designed for R-134A refrigerant systems with a nominal capacity of 2 to 3 tons. It suits automotive air conditioning repair or retrofit projects where precise refrigerant metering is required. The externally adjustable design allows technicians to fine-tune superheat settings on the vehicle. Buyers needing a non-adjustable valve or a different refrigerant compatibility should look elsewhere.

Thermals noise and power draw

The valve operates mechanically across an evaporator temperature range of -40 to 60 degrees without electrical consumption or moving fans. It maintains accuracy over wide load variations to minimise hunting, flood back and coil starving problems during normal system cycling. No power supply or wiring is involved in its operation. Installers should verify system pressures match the valve’s intended range before fitting.

Build quality and connectors

The brass body features a 3/8 inch SAE flare inlet and a 1/2 inch SAE flare outlet with a 3/8 x 1/4 inch reducing flare nut included. A 60 inch capillary tube and sensing bulb mounting clamp are supplied for secure evaporator attachment. The flare connections demand clean, square tubing cuts and correct torque to prevent leaks. Technicians without flare tooling or torque wrenches will need those items to complete the installation.

Questions about this item

How do I install the Parker CCJW expansion valve and which step is commonly missed?

Connect the 3/8 in SAE flare inlet and 1/2 in SAE flare outlet, secure the 60 in capillary sensing bulb to the suction line with the included mounting clamp, then adjust the external superheat setting; the step often missed is tightening the bulb clamp firmly for full thermal contact.

What maintenance or replacement will the Parker CCJW valve need over time?

The externally adjustable design lets you re-calibrate superheat as the system ages; if the power element loses charge or the valve body leaks refrigerant, the complete valve assembly must be replaced.

What is the first limit reached on the Parker CCJW valve during sustained high-load operation?

The nominal capacity tops out at 3 tons for R-134A, and the ambient temperature range ends at 60 °C; beyond either limit the valve can no longer control superheat accurately.
