Product Description
Product Overview
The V6016 motorized valve is a compact on/off valve for HVAC water-loop control. Powered by a hysteresis synchronous motor, it opens and closes the flow path in response to a thermostat or controller signal. The series includes both two-way and three-way configurations in DN15~DN25 sizes, making it suitable for fan-coil units, air handling units and small commercial hydronic systems.
Key Features
- Hysteresis synchronous motor for reliable open/close operation
- Low power consumption (2 VA) only during switching
- Manual override for commissioning and emergency use
- Brass valve body and stem for corrosion resistance
- BSP threaded connection for easy installation
- 2-way and 3-way options available in DN15~DN25
- Quiet operation with full opening in 10 seconds

Installation Notes
- Confirm the flow direction matches the arrow on the valve body
- Ensure the supply voltage matches the actuator rating
- Leave at least 85 mm clearance above the actuator for removal and service
- Install with the actuator upright or horizontal; avoid inverted mounting
- Power off before installation or maintenance
- Flush the piping system before commissioning to protect internal parts
