# DN Series 220V Electric Ball Valve Switch Type Date: 2026-07-18 Categories: Solenoid Valve URL: https://homipneu.com/dn-series-220v-electric-ball-valve-switch-type.html ## Product Summary The DN30 Series is a self-diagnostic intelligent electric ball valve designed for on/off control in heating systems and air-conditioning fan coil systems. External LED indicators use red and green lights to show whether the valve opens and closes correctly, providing a self-diagnostic function. When the valve is fully open, the red light turns off and the green light turns on. When the valve is fully closed, the green light turns off and the red light turns on. If the valve is not fully opened or closed, both the red and green lights remain on. Maintenance personnel can quickly identify the valve status simply by checking the indicators. The valve is especially suitable for installation in confined, dark, or difficult-to-access locations, such as terminal water-circuit control points in central air-conditioning systems. ### Specifications **Item** **Specification** Power Supply AC 220 V, 50/60 Hz; AC 24 V, 50/60 Hz Operating Power 6 W or 9 W, consumed only while the valve is opening or closing Opening/Closing Time 15 seconds Protection Rating IP54 Operating Mode 90° quarter-turn operation with forward/reverse rotation, or 360° rotation Ambient Temperature 2–60°C Applicable Media Hot and cold water; ethylene glycol aqueous solutions with a concentration of up to 60% Medium Temperature 2–95°C Maximum Closing Pressure Differential 0.6 MPa for 2-way valves; 0.3 MPa for 3-way valves Cable Length 50 cm; customizable Actuator Dimensions 63 × 80 × 83.5 mm ### Model Selection **Product Model** **Connection Size** **Corresponding PPR Pipe Size** **Corresponding Metal Pipe Size** **Ball Bore Diameter** **Length (L)** **Height (H)** **Thread Diameter** **Weight (kg)** DN15 1/2″ PPR20 DN15 12 mm 50 mm 122 mm 20 mm 0.415 DN20 3/4″ PPR25 DN20 17 mm 59 mm 129 mm 25 mm 0.463 DN25 1″ PPR32 DN25 20 mm 65 mm 133 mm 32 mm 0.581 DN32 1 1/4″ PPR40 DN32 25 mm 74 mm 145 mm 40 mm 0.800 DN40 1 1/2″ PPR50 DN40 30 mm 82 mm 150 mm 50 mm 0.850 DN50 2″ PPR63 DN50 37 mm 96 mm 165 mm 57 mm 1.200 ### 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** Suitable for fan coil water control where the valve needs to open or close the flow path according to temperature control signals. **Heating Pipeline Control** Applied in hot water pipelines, heating terminals, temperature control loops, and building water distribution systems. **Central Air-Conditioning Terminal Circuits** Used at terminal water-circuit control points in central air-conditioning systems, especially where installation space is limited or valve status needs to be checked quickly. **OEM Equipment and Maintenance Replacement** Suitable for HVAC equipment manufacturers, water control system builders, spare parts programs, distributor stock, and maintenance replacement projects. ### Why Choose HOMIPNEU HOMIPNEU supplies electric ball valves, solenoid valves, pneumatic valves, pneumatic fittings, cylinders, air hoses, air preparation units, and related fluid and compressed air control components for industrial automation and HVAC applications.

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.
