Copeland Comfort Control (White Rodgers) F84-0434 Assembly

The Copeland Comfort Control (White Rodgers) F84-0434 Assembly is a critical 1-inch internal stem and valve assembly engineered specifically for 1311 and 1361 series hydronic zone valves. Designed for heavy-duty service in residential and commercial hot water heating systems, this replacement valve assembly ensures precise flow control and reliable zone isolation. As a veteran-grade White Rodgers F84-0434 part, it is built to the exact specifications of the 1311-103 and 1361-103 models, handling maximum water temperatures up to 240°F and system pressures of 50 PSI. The assembly features a stainless steel stem and high-temp seals to maintain a 15 PSI maximum differential across the valve. When completing a hydronic zone valve repair, professionals prefer this internal assembly for its seamless integration with existing valve bodies, allowing for rapid restoration of the 24VAC control circuit without a full system overhaul. Proper maintenance of the valve bore and the use of silicone-based lubricants during seating are recommended to maximize the service life of this internal valve assembly.

• Direct Compatibility: Specifically designed as the primary internal component for White Rodgers 1" zone valves (1311-103 and 1361-103).
• Rugged Construction: Features a stainless steel stem and durable internal components to withstand high-temperature hydronic cycling.
• Simplified Maintenance: Allows technicians to resolve leak issues or mechanical failures by replacing the internal assembly rather than the entire valve body.
• High Performance: Rated for closed-loop hydronic systems with a flow capacity of approximately 37.0 GPM at 1 PSI drop.
• Standard 24V Integration: Engineered to work with both 2-wire and 3-wire motor actuators used in the 1300 series lineup.

Is the F84-0434 compatible with 3/4" valves?
No, this specific assembly is sized for 1" valve bodies. For 3/4" 1311/1361 series valves, you should use the F84-0433 assembly to ensure a proper seat and seal.

Does this assembly include the motor actuator?
This is the internal valve and stem assembly only. If your actuator has failed, you will need to source the F19-0097 (3-wire) or F19-0104 (2-wire) motor separately.

Do I need to drain the system to install this part?
Yes. Unlike replacing just the motor head, replacing the F84-0434 internal assembly requires draining the local zone or the entire system to prevent scalding and water damage once the valve plate is unlatched.
