Detailed Description

Nissens 9991034 is an aluminum A/C expansion valve developed for precise refrigerant control in automotive air conditioning systems. As a block-type valve, it meters refrigerant flow through the HVAC circuit to support proper evaporator operation and system balance. The part is specified for R134 refrigerant and is manufactured under standards that emphasize validation of pressure performance, sealing integrity, opening characteristics, set-point accuracy, and internal finish. The part number 9991034 is also cross-referenced to LR093044 and T2H8163 for the same application.

Fits 2017-2024 Jaguar F-Pace, N/A. Fits 2016-2024 Jaguar XF, N/A. Fits 2018-2024 Land Rover Range Rover Velar, N/A. Fits 2017-2020 Jaguar XE, N/A. This fitment coverage makes 9991034 a relevant replacement for Jaguar XF and related Jaguar and Land Rover HVAC service needs when the vehicle uses the listed block expansion valve setup.

What It Helps Address

• Irregular refrigerant metering through the A/C system.
• Loss of cooling performance caused by a worn expansion valve.
• Sealing issues at the valve connection points.
• HVAC operation problems tied to incorrect opening behavior.
• Service replacement needs for R134-equipped systems.

Installation Notes

Verify the refrigerant type, valve style, and connector layout before installation. Replace the valve only after confirming the system is clean and ready for service, and follow the vehicle manufacturer’s A/C service procedures. Use the included O-rings and mounting hardware where applicable.

Quality Assurance

Nissens manufactures thermal expansion valves under strict control standards and validates pressure performance, tightness, opening, set-point setting, and internal finish to OE-matching requirements.
