White-Rodgers 1361-103 Valve

The White-Rodgers 1361-103 is a 1-inch, 2-wire zone valve engineered for hydronic heating systems requiring high-reliability flow control. Operating on 24V AC, this normally closed valve is designed for 1" sweat connections and features an integrated auxiliary switch (SPST) rated for 2.0A of current to effectively sequence burners or circulator relays. This unit is built to manage systems with a maximum pressure of 50 PSI and can handle water temperatures up to 240°F, making it a staple for light commercial and standard residential boiler applications. The stainless steel valve stem and heavy-duty motor assembly ensure longevity in high-duty cycle environments.

For service technicians, the 1361-103 offers significant field advantages, including a motor assembly that can be removed from the valve body without draining the secondary loop. Its automatic recycling manual operator provides an immediate visual status of the valve position, simplifying troubleshooting during startup or maintenance. With a 37.0 Cv flow capacity and a maximum differential of 15 PSI, this valve minimizes friction loss—equivalent to approximately 4 feet of copper tubing—ensuring the circulator operates within its intended curve. This 1" 24v 2-WireZoneVlv w/AuxSw is optimal for zoning hydronic systems where quiet operation and precise temperature management are critical.

Key Benefits

• Efficient Sequencing: The built-in auxiliary contacts allow for seamless control of the boiler burner or circulator relay without additional relays.
• Maintenance Ease: Removable motor head enables quick replacement or repair without the need to purge or drain the entire hydronic zone.
• Robust Construction: Features a corrosion-resistant stainless steel stem and a self-aligning barrel-type design to prevent sticking.
• Visual Diagnostics: The manual open dial shows the flow state at a glance and allows for manual override during power outages.
• Quiet Performance: Specifically engineered for hydronic comfort, minimizing water hammer and operational noise in residential spaces.

Common Questions

Can the 1361-103 be installed in any orientation?
The valve body can be mounted in any position except upside down to prevent moisture or debris from entering the motor housing. Ensure adequate clearance for head removal.

How many of these valves can a 40VA transformer support?
A standard 40VA transformer is typically rated to handle up to four 1361 series zone valves, given the 0.2A running current per unit.

Does this valve provide a 100% bubble-tight seal?
No, these valves are designed with a permissible leakage rate of approximately 4 gallons per hour at rated differential; they are flow control valves, not primary shut-off valves.
