White-Rodgers F84-0433 Valve Assembly

The White-Rodgers F84-0433 Valve Assembly is a high-performance replacement component engineered for 3/4-inch hydronic zone valves, specifically serving as a direct fit for 1,300 series models including the 1311-102 (3-wire) and 1361-102 (2-wire). For veteran contractors, this assembly is the correct choice for restoring precise flow control and pressure regulation in residential and light commercial boiler systems without requiring a full valve body replacement. It features a rugged stainless steel valve stem and a heavy-duty brass disc designed to withstand system pressures up to 50 PSI and water temperatures as high as 240°F.

When executing a zone valve repair, this unit maintains a reliable seal with a maximum 15 PSI differential across the valve. The assembly integrates seamlessly with existing power heads, allowing technicians to service internal components by unlatching the top and swapping the stem assembly once the system is drained and depressurized. Using the F84-0433 stem assembly ensures compatibility with auxiliary switch circuits (2.0A at 24VAC) used for burner or circulator relay signaling.

• Direct OEM Compatibility: Engineered specifically for 3/4" White-Rodgers 1311 and 1361 series hydronic valves.
• Industrial-Grade Construction: Features a stainless steel stem for enhanced corrosion resistance and long-term durability in high-cycle heating applications.
• Cost-Effective Maintenance: Restores proper zone flow control and stops internal bypass leakage without the labor intensive task of sweating in a new valve body.
• High Thermal Tolerance: Rated for hydronic systems operating at temperatures up to 240°F, ensuring performance in demanding boiler loops.

• Which models does the F84-0433 fit? This assembly is primarily used for the 3/4-inch 1311-102 and 1361-102 models. For 1-inch or 1-1/4 inch valves, different assembly part numbers are required.
• Do I need to drain the system to install this? Yes. Unlike motor replacements, replacing the internal valve assembly requires opening the pressurized portion of the valve body, meaning the system or zone must be drained and the water cooled to prevent injury.
• Is this compatible with 2-wire and 3-wire systems? Yes, the F84-0433 is the mechanical valve component and works regardless of whether the actuator is a 2-wire or 3-wire motor configuration.
