Spartan Valves ME4530S Actuator
The Spartan Valves ME4530S Actuator is a professional-grade 24V 2-position spring return actuator engineered for reliable on-off control in hydronic systems. Featuring a normally closed (N/C) configuration, this unit ensures a fail-safe "stem down" position during power disruptions, making it an essential component for HVAC zone valve control. Designed with a high-strength, glass-filled nylon composite housing, the ME4530S utilizes an electric gear motor for consistent performance and torque when managing hot water, chilled water, or low-pressure steam applications. The inclusion of an auxiliary end switch (AUX) allows for seamless integration with secondary equipment like pumps or fan relays, streamlining complex commercial HVAC automation sequences. With its universal M30 quick disconnect thumbnut, installation onto Spartan V200 and V300 valve bodies is efficient and tool-free, reducing labor time for contractors on-site. This spring return motorized valve actuator is built for heavy-duty cycling in terminal units, ensuring long-term stability and precise flow regulation in demanding environments.
Key Benefits- Fail-Safe Protection: The reliable spring return mechanism automatically drives the valve to a normally closed position upon power loss, preventing unauthorized flow.
- System Integration: Integrated auxiliary end switch provides dry contact feedback to signal boilers or chillers, enhancing total system efficiency.
- Universal Compatibility: Features an M30 x 1.5 mounting connection, allowing for easy field replacement on a wide variety of Spartan valve bodies.
- Thermal Protection: Designed with an insulating collar that isolates the electric motor from valve body heat, extending the life of the internal components.
- Manual Override & Monitoring: Includes a visible dial-type position indicator for quick visual confirmation of valve status during troubleshooting.
Is the ME4530S compatible with 3-way valves?
Yes, this actuator is fully compatible with both 2-way and 3-way Spartan zone valve bodies. The M30 mount ensures a standardized fit across the V200 and V300 series, provided the stroke requirements match the 2-position operation.
How do I wire the auxiliary switch for a pump relay?
The AUX switch in the ME4530S provides a dry contact signal that closes when the actuator reaches its full open position. This is typically wired in series with the 24V coil of a pump starter or terminal unit controller to ensure the pump only runs when the valve is open.
Can this actuator handle low-pressure steam?
The Spartan ME4430/4530 series is rated for use with low-pressure steam up to 15 psig, as well as water/glycol mixtures up to 50%, making it versatile for diverse mechanical room setups.
