Avoid solenoid valves that have high power consumption, overheat, and are noisy. Motorized ball valves are energy-efficient, consuming power only during state changes. They can be easily powered directly from the 24VDC source used by the entire TapHome system.
Motorized ball valves are available in two versions:
- NO version (normally open when unpowered): Suitable for controlling the main water supply based on data from a flood sensor or a pulse flow meter measuring water consumption.
- NC version (normally closed when unpowered): Suitable for irrigation control.
The motorized ball valve consists of a ball valve with a servo motor that rotates the ball valve by 90º. The servo motor has a built-in limit switch that cuts off power when the valve reaches its fully open or closed position. The motor is powered directly by 24VDC, has zero consumption when in the open or closed state, and very low consumption during state transitions.
The motorized ball valve is controlled by a single DO relay output. In the "NO - normally open" version, the water supply remains open in the event of a system failure. In the "NC - normally closed" version, the water supply remains closed in the event of a system failure.
Features

- Opening/closing time: ≤ 15s
- Max. pressure: 1.6 MPa (0 - 16 bar)
- Connection: G-thread, diameter 1"
- Medium: Hot water, Cold water, Water + 50% glycol solution
- Medium temperature: -10~100°C
- Valve material: Forged brass with nickel-plated surface
- Protection rating: IP65
- Servo dimensions: 80 x 63 x 68mm (see photo)
Wiring
- Brown cable: 24 VDC
- Yellow cable: GND
- Blue cable:
- NO: 24 VDC = closed water flow
- NC: 24 VDC = open water flow
Installation Notes
Mount the servo motor above or beside the pipe, never below it.
Condensation from a cold pipe and water from any leak run down the valve. With the servo motor below the pipe, the water gets inside it and significantly shortens its service life. The risk is highest in cooling and with cold water, for example on the main water supply in a damp basement.
- The valve and pipes can be installed horizontally or vertically
- The valve thread must comply with the international standard for pipe threads, type G
- Before installation, ensure that both the valve and pipes are free of debris
