Expansion Valve, Air Conditioning Flow Control Unit SKU: QT58375

This expansion valve regulates refrigerant flow between the high-pressure and low-pressure sides of the AC system, critical for stable cooling and pressure control. A failing valve can cause poor cooling, pressure swings, or erratic operation.

Manufactured with internal metering components and sealed housings, it’s built to manage temperature and pressure shifts under normal HVAC operating conditions.

• Air conditioning expansion valve for precise refrigerant metering
• Sealed construction to maintain internal integrity and prevent leakage
• Handles system pressure and thermal cycling in cab HVAC systems
• Designed for direct integration into standard refrigerant line paths

Installation Tip: When replacing, ensure the lines are clean and dry. Mount the valve using proper torque, align it for correct flow direction, and make sure the sensing bulb is secured with proper contact and insulation. Evacuate the system fully before charging.

A dependable replacement valve that helps stabilize cooling performance and protect your AC system under field conditions.
