Spartan Valves ME7340 Actuator

The Spartan Valves ME7340 is a high-precision 24VAC modulating actuator designed for seamless integration into modern building automation systems (BMS). As the direct replacement for the ME4340, this unit maintains a standard 2-10VDC control signal, making it the ideal choice for contractors looking to upgrade or repair existing terminal unit and zone valve configurations without altering control logic. This non-spring return (NSR) gearmotor actuator provides stable, proportional control of water-based media or low-pressure steam, ensuring accurate positioning and optimal thermal regulation in energy-efficient HVAC applications.

Built with a compact footprint and NEMA 3 (IP54) protection, the ME7340 electric actuator thrives in tight mechanical spaces while offering a 360-degree installation range. It features a digital LCD that displays real-time valve stroke status and operating modes, allowing for rapid field diagnostics. With a standard 200N (45lbf) force and a 15s/mm response speed, this Spartan scientific ME7340 ensures reliable performance in AHU and VAV system environments, effectively replacing legacy ME4340 actuators with enhanced feedback capabilities for centralized monitoring.

• Complete Compatibility: Operates as the official replacement for ME4340, utilizing the same 2-10VDC modulating input for hassle-free swaps.
• Robust Environmental Protection: Features a polyamide casing and polycarbonate cover rated for IP54/NEMA 3 to resist dust and moisture.
• Visual Diagnostics: The integrated blue backlit LCD provides instant verification of control voltage and current valve position.
• Flexible Wiring: Comes standard with an FT6 rated pluggable cable, simplifying connections to 24VAC/VDC power supplies.
• Versatile Application: Suitable for a wide range of Spartan zone valves, supporting stroke ranges from 2.0mm to 8.5mm through NFC adjustment.

What is the primary difference between the ME7340 and the ME4340?
The ME7340 is the direct successor to the ME4340. While it retains the technical footprint and 24VAC/2-10VDC operation of its predecessor, the ME7340 offers improved feedback signals and a digital display for modern system integration.

Does this actuator return to a default position on power loss?
No, this is a non-spring return (NSR) actuator. In the event of a power failure, the motor will fail-in-place at the last known position.

Can I use a 24VDC power supply instead of AC?
Yes, the Spartan ME7340 is designed to accept either 24VAC (-10%/+20%) or 24VDC (-20%/+20%) as the primary power source.
