BVSDRY01 -- Motor for Ball Valve (Wired Control)
Product Description
This motor converts existing ball valve shut-off valves into intelligent water control devices. An innovative clamping mechanism allows installation within minutes without additional tools on shut-off valves with pipe diameters between 0.5 and 1.5 inches. A patented coupling mechanism delivers up to 8 Nm of torque to operate even rusty and aged valves.
Key Features:
- Water and dust protected (IP66) up to the power supply, suitable for humid, dirty, and outdoor environments
- Automatic weekly valve exercise: one close/open movement (1/8 turn) removes deposits in the valve
- Rotation angle measurement and end position detection
- Wired leak sensor can be connected
- 12 V power supply via waterproof connector
Control: Via a 120 cm two-wire cable (dry contact). The cable can be connected to any relay or dry contact switch:
- Short circuit at the ends → Valve closes
- Remove short circuit → Valve opens
Compatible with smart home systems: Shelly, Z-Wave, SmartThings, Bosch, Homematic, and alarm systems.
If no switching contact can be installed near the valve, the two-wire cable can be extended wirelessly. See BVSDRY02.
Installation
- Disconnect the device from power
- Select the correct fork side matching the valve handle width
- Ensure that the clamping knobs and handle point in opposite directions (the handle must be able to move freely)
- Tighten the clamps by hand while holding the BVS in place
- Optional: Remove the dust cap and connect the local water sensor
- Connect the DC adapter to the BVS power cable, tighten the waterproof seal
- Plug the power adapter into a 230 V outlet
Adjusting the Pipe Clamps
The pipe clamps are positioned in the center of the bracket as shipped. They can be shifted to the right or left by tightening them fully while not mounted on the pipe. Shifting them adjusts them to different pipe thicknesses.
For even larger pipes, the clamps can be replaced with a pair of larger clamps with SKU BVSCMP01 (available in the shop). This enables operation on pipes up to 2 inches.
Calibration
The device measures the rotation angle and end positions of the handle to approach the endpoints gently and avoid mechanical stress. Each time the device is powered on, it first performs a calibration run.
Procedure: Press the button once to start the process. Observe the handle movements. After 10--20 seconds, the device is ready for operation.
Calibration requires the BVS to be mounted on a ball valve. Without a valve, calibration will abort and handle operation (button and radio command) is disabled.
Connecting to Switching Contacts
Connect the audio plug of the included 100 cm cable to the output on the power cable. Connect the two bare ends to the output of your smart home or alarm system.
- Short circuit at the ends → Valve closes
- Remove short circuit → Valve opens
The control cable can be extended with a 1.5 m extension ALIEXT01 (available in the shop).
Manual Operation
The device has a single button with a built-in tri-color LED.
- Short click: Toggle valve (open/close)
- Hold for several seconds: Continuous operation (the BVS assists with counting seconds by beeping every second)
- Hold for 2 seconds (2 beeps): Deactivate alarm
The device is designed for outdoor use and must prevent malfunctions caused by water droplets. Therefore, please press the button firmly, even for a short click.
