Carrier EP13BZ271 Service Valve

The Carrier EP13BZ271 7/8" Suction Service Valve is a critical OEM replacement component designed for high-performance HVAC compressor service. This heavy-duty suction line valve features precision-machined brass construction and is the direct factory replacement for the legacy 329789-401 model. Engineered to facilitate efficient refrigerant pump down and system isolation, this valve allows technicians to access the refrigeration circuit for pressure testing, charging, or recovery without evacuating the entire system charge. The EP13BZ271 utilizes a 7/8 inch connection diameter, ensuring a secure, leak-free seal in high-pressure environments common in residential and light commercial condensing units. This re-engineered version features an upgraded internal gasket designed to eliminate the common O-ring failures found in older iterations, providing superior long-term reliability. For contractors managing Carrier technical specifications, this valve is essential for maintaining the integrity of split system air conditioners and heat pumps, ensuring streamlined serviceability and consistent volumetric flow throughout the suction path.

• Direct OEM Compatibility: Engineered as the specific replacement for 329789-401, ensuring perfect fitment and alignment with existing suction lines.
• Enhanced Leak Protection: Features a high-grade valve gasket and precision-threaded service port to prevent refrigerant loss during high-ambient operation.
• Field Service Efficiency: Simplifies refrigerant recovery and system evacuation procedures by providing reliable shut-off capability at the outdoor unit.
• Rugged Durability: Constructed from corrosion-resistant brass and copper materials to withstand environmental exposure and vibration.

Is the EP13BZ271 compatible with R-410A systems?
Yes, this suction service valve is designed to handle the high-pressure requirements of modern R-410A refrigerants, as well as legacy R-22 applications.

Does this valve replace the older 329789-401 model?
Correct. The EP13BZ271 is the official manufacturer-designated direct replacement for the 329789-401, featuring improved internal sealing components.

Can this valve be used for liquid line applications?
No, this is specifically sized as a 7/8" suction line valve. For liquid line repairs, a smaller diameter liquid line service valve must be utilized to match the specific tube sizing.
