A: Thermal: 2–5 min full open/close. Motorized: 5–30 sec.
A: Yes, but ensure thermostat relay can handle actuator inrush current (typically ≤ 0.5A for thermal, 1A for motorized). 14. Summary Table – Quick Reference | Feature | Thermal Actuator (NC) | Motorized Zone Valve | |---------|----------------------|----------------------| | Best for | Underfloor manifolds | Radiators, fan coils | | Speed | Slow (2-5 min) | Fast (10-30 sec) | | Power consumption | ~2W | ~5-8W | | Noise | Silent | Slight hum during open/close | | Fail-safe | Usually no (unless spring return) | Optional spring return | | End switch | No | Yes (for boiler interlock) | | Manual override | Yes (screw down or lever) | Yes (lever) | This guide should help you confidently select, install, and maintain an ACSYS motorized valve for any hydronic heating or cooling application. Always refer to the specific product datasheet, as ACSYS offers multiple series with different mechanical and electrical interfaces. acsys motorized valve
A: Yes, for most models (valve body stays in pipe). Turn off power, unclip actuator, replace. A: Thermal: 2–5 min full open/close
An ACSYS motorized valve is an electrically actuated valve used primarily in HVAC (Heating, Ventilation, and Air Conditioning) systems, underfloor heating, fan coil units, and district heating/cooling networks. ACSYS is a brand known for manufacturing reliable, compact, and energy-efficient motorized control valves, often used as an alternative to Honeywell, Danfoss, or Siemens in residential and light commercial projects. A: Yes, for most models (valve body stays in pipe)
