Product Features
Electric On-Off Ball Valve Control
The DN Series electric ball valve is designed for automatic on-off control in HVAC water systems. It uses an electric actuator to open or close the ball valve, making it suitable for heating, cooling, and fan coil water circuit control.
Switch Type Operation
The switch type design is suitable for applications that require simple open and close control. It can be used in equipment where the valve only needs to switch between fully open and fully closed positions.
Self-Diagnostic LED Indicator
The actuator uses red and green LED indicators to show valve status. When the valve is fully open, the green light turns on. When fully closed, the red light turns on. If the valve is not fully open or closed, both lights remain on for quick troubleshooting.
Suitable for Confined Installation Areas
The valve is suitable for terminal water-circuit control points in central air-conditioning systems, especially in narrow, dark, or difficult-to-access installation locations where visual status indication helps maintenance work.
For Hot and Cold Water Systems
The valve can be used for hot water, cold water, and ethylene glycol aqueous solutions up to 60% concentration when pressure, temperature, connection size, and sealing compatibility match the system requirements.
OEM and Distributor Supply Friendly
HOMIPNEU supports model confirmation, bulk orders, export packaging, cable customization, and OEM supply for HVAC equipment suppliers, valve distributors, water control system builders, and industrial automation customers.
Applications
HVAC Water Control Systems
Used for automatic on-off control in heating systems, cooling systems, air-conditioning water circuits, and central HVAC terminal equipment.
Fan Coil Unit Systems

FAQ
What is the DN Series electric ball valve used for?
The DN Series electric ball valve is used for automatic on-off control of hot water, cold water, and compatible glycol water solutions in heating systems, air-conditioning systems, fan coil units, and HVAC terminal circuits.
Is this valve a solenoid valve?
No. This product is an electric ball valve, also called a motorized ball valve. It uses an electric actuator to rotate the ball valve, while a solenoid valve uses an electromagnetic coil to open or close the flow path.
What does switch type mean?
Switch type means the valve is mainly used for simple open and close control. It is suitable for systems that require fully open or fully closed valve positions.
What voltage options are available?
The page lists AC 220V, 50/60Hz and AC 24V, 50/60Hz options. Voltage should be confirmed before ordering to match the control system.
Can this valve be used in fan coil systems?
Yes. It is suitable for air-conditioning fan coil systems and terminal water-circuit control when valve size, voltage, medium, pressure, and wiring match the system requirements.
Can this valve be used with glycol water?
Yes. The valve can be used with ethylene glycol aqueous solutions up to 60% concentration when temperature, pressure, and material compatibility meet the application requirements.
What should be confirmed before ordering?
Please confirm the model, connection size, power supply, 2-way or 3-way structure, cable length, control wiring, applicable medium, pressure differential, medium temperature, installation space, and order quantity.
