Electric Actuated On-Off Control Valves
Electric motorised on-off control valves combine a small ball valve with an electric motor mounted directly on top, giving remote open-close on water, heating and building services lines. Needing no compressed air, they suit residential, building and light industrial applications and can be driven directly by a thermostat, float switch or automation contact.
Mini motorised valves have 1/2″–1″ threaded connections, stainless steel or brass bodies and PTFE seats; they open and close in 5–7 seconds on 220 V AC, 24 V AC, 24 V DC and 12 V DC supplies. Larger valves use rotary electric actuators with ISO 5211 flanges.
Main Applications
- Water inlet shut-off in smart homes and building automation
- Zone valves in combi boiler, boiler and solar circuits
- Fill control of water tanks with float or level relay
- Time-programmed line opening in irrigation systems
- Main water shut-off linked to a leak detector
- Automatic water feed on industrial cooling and washing machines

Mini motorised valves are intended for low-pressure building lines such as clean water and heating water; on lines exceeding 10 bar or 80 °C, choose actuated ball valves of a higher pressure class. The supply voltage must match the voltage of the control contact.
Advantages
Air-Free Automation
- No compressor needed.
- Easy to apply in residential and building services.
Fast Movement

Request a quote for electric motorised on-off valves by stating connection size, body material, supply voltage, number of ways and control type.
How to Choose?
- Define the lineMini motorised valve if pressure stays below 10 bar and temperature below 80 °C; otherwise an actuated industrial ball valve.
- Choose the voltageSelect a 12 V DC, 24 V or 220 V AC type to match the thermostat, float switch or PLC output.
- Decide the number of waysUse a 2/2-way valve for shut-off and a 3/2-way valve for diverting between two lines.
- Choose the body materialStainless for drinking water and food, brass for general heating and building water.
