Carrier EF33CZ213 Gas Valve

The Carrier EF33CZ213 Gas Valve is a critical OEM replacement gas valve designed for single-stage heating applications in Carrier, Bryant, and Payne equipment. Engineered for use with natural gas, this redundant gas valve features a 1/2 inch NPT inlet and a 3/4 inch NPT outlet, ensuring high-capacity flow for residential and light commercial furnaces or packaged units. The integrated pressure regulator is factory-set to 3.5 inches W.C., maintaining precise manifold pressure for optimal combustion and heat output. Built by Basotrol (Model G196HGH-2), this component supports direct spark ignition (DSI) and intermittent pilot systems, operating on a standard 24V 60Hz signal. As a Factory Authorized Part, it serves as a direct drop-in for legacy part numbers including EF33CZ196, EF33CZ211, and EF33CZ212, providing technicians with a reliable solution for restoring system safety and efficiency without the need for field modifications.

Key Benefits:

• Direct OEM Compatibility: Verified fit for a wide range of Carrier-produced air handlers and RTUs, ensuring electrical and physical alignment.
• Redundant Safety Design: Features an internal manual shut-off and secondary solenoid for secure fuel management.
• Precision Regulation: Consistent 3.5" W.C. delivery optimizes fuel consumption and prevents over-firing the heat exchanger.
• Versatile Ignition Support: Compatible with both direct spark and intermittent pilot 24V gas furnace controls.
• High Capacity Throughput: Rated for up to 175,000 BTU/HR to meet the demands of high-output heating systems.

Common Questions:

Can the Carrier EF33CZ213 be converted for Liquid Propane (LP) use?
This specific model is calibrated for natural gas at 3.5" W.C. Any conversion to LP requires an OEM-approved conversion kit and must be verified against the manufacturer’s specific manifold pressure requirements for the appliance model.

How do I confirm this is the correct valve for my furnace or RTU?
Technicians should cross-reference the part number found on the existing valve or check the unit's rating plate. This valve replaces multiple older revisions including EF33CZ196, EF33CZ197, EF33CZ198, EF33CZ207, EF33CZ211, and EF33CZ212.

What are the electrical requirements for the solenoid?
The valve operates on a 24-volt AC circuit at 60Hz. It pulls approximately 0.3 Amps (5 Watts), making it compatible with standard HVAC 40VA transformers and integrated ignition control boards.
