Spartan Valves ME1708 Actuator
The Spartan Valves ME1708 Actuator is a professional-grade thermoelectric actuator engineered for precise terminal unit control in hydronic heating and cooling systems. Operating on a 24V AC/DC nominal supply, this normally closed (N/C) unit utilize a highly refined wax-filled element with a PTC semi-conductive disc to ensure silent, reliable operation without the mechanical noise associated with motorized gears. The fail-stem-down orientation provides an inherent fail-safe return during power loss, critical for system protection and load management.
Designed for field versatility, the ME1708 features a right-angle (R/A) mounting profile and a quick bayonet coupling for tool-free installation on a variety of zone valve bodies. It is compatible with 1/2", 3/4", and 1" Spartan valve bodies, supporting media temperatures up to 250°F (120°C) and low-pressure steam up to 15 PSI. With a life expectancy rated for 1.5 million cycles, this actuator is the standard for long-term HVAC valve automation in commercial and residential fan coil units or baseboard applications.
Key Technician Benefits:
- Fail-Safe Security: Integrated spring return functionality ensures the valve defaults to the stem-down position upon power interruption.
- Universal Compatibility: Fits V240, V243, V320, and V325 series valve bodies with NPT, sweat, or union connections.
- Maintenance-Free Design: Features a patented packless elastomer seal and wax element technology for multi-decade service life.
- Visual Diagnostics: Includes a top-mounted position indicator for immediate visual confirmation of the valve's operating state, even in low-light utility closets.
- Efficient Performance: Low power consumption at approximately 1W (2VA) reduces the load on control transformers.
Common Technical Questions:
Is the ME1708 compatible with modulating controllers?
While the ME1708 is primarily a two-position (on/off) actuator, it can be utilized with pulse-width modulation (PWM) signals from compatible building automation systems to simulate proportional control.
What is the "First-Open" function?
The unit is shipped in the "First-Open" state to allow for system filling and flushing before power is connected. This feature is automatically released after the first 6 minutes of continuous power application.
Can this be mounted in any orientation?
For optimal reliability, it is recommended to mount the actuator between the vertical and 90-degree horizontal position; mounting the unit upside down is not recommended as it may allow moisture to collect in the housing.
