Expansion Valve, Precision Refrigerant Control Unit SKU: QT58400

This expansion valve meters refrigerant flow between the high-pressure and low-pressure sides of your AC system, helping maintain stable cooling output and pressure balance.

Constructed with internal metering and sealed housing, it’s engineered to handle thermal cycling and system pressure changes typical in HVAC use.

• Expansion valve for precision refrigerant metering
• Sealed design to maintain internal integrity and prevent leaks
• Handles pressure and thermal cycling in AC systems
• Direct-fit for standard HVAC refrigerant line layouts

Installation Tip: Ensure refrigerant lines are clean and dry before installing. Mount the valve in proper orientation, securely attach the sensing bulb, evacuate the system fully, then charge with correct refrigerant to ensure proper performance.

A reliable replacement part to help stabilize cooling and protect your cab’s AC system under daily use.
