Spartan Valves ME-4840B Actuator
The Spartan Valves ME-4840B Actuator is a critical component for technicians managing terminal unit and zone valve applications. This 24Vac spring return proportional actuator is engineered for precise modulation, utilizing a microprocessor-based control system to drive 2, 3, or 4-port valves. Operating on a 0-10Vdc control signal, the unit features an internal AC hysteresis brushless motor that provides reliable 28lbs (120N) of output force. The normally open (N/O) fail-safe mechanism ensures the valve returns to the stem-up position upon power loss, a vital safety feature for chilled water, hot water, and low-pressure steam systems using balanced valve cartridges. Integration is streamlined with a 1-5Vdc feedback signal for real-time monitoring of valve position. This zone valve actuator accommodates various media temperatures from 35°F to 250°F, making it a versatile choice for Building Automation Systems (BAS) and complex commercial HVAC projects where accurate flow regulation is non-negotiable.
Key Benefits:- Fail-Safe Reliability: Internal spring return mechanism ensures the valve defaults to an open position during power interruptions.
- Precise Modulation: Features a quadrature optical encoder for drift-free positioning across 100,000+ cycles.
- Field Versatility: Direct or reverse acting modes are easily selectable via internal jumpers to match controller requirements.
- Self-Calibrating: Automatic re-span operation at power-up confirms 4mm travel and optimizes performance without manual tuning.
- Rugged Construction: IP20/NEMA 1 rated enclosure designed for vertical or horizontal mounting in demanding mechanical rooms.
- What valve bodies are compatible with this actuator? This unit is designed for use with Spartan EB type balanced cartridges for water and EV type cartridges for steam.
- Can I monitor the exact position of the valve stem? Yes, the 1-5Vdc output signal on the green wire allows for remote monitoring by a BAS or secondary controller.
- How do I prevent over-tightening during installation? The mounting thumbnut should be hand-tightened only; using tools can damage the actuator base or valve threads.
