BVSDRY02 -- Motor for Ball Valve (Remote Control via Contact Controller)
Product Description
The 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 remote interface unit (DRYLWE02) with a robust LoRa radio link, controlled by dry contact switches.
- Closed contact → Valve closes
- Open contact → Valve opens
Compatible with smart home systems: Shelly, Z-Wave, SmartThings, Bosch, Homematic, and alarm systems.
Installation
All installation information can be found in the manual for the ball valve motor BVSLWE02.
- 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.
Connecting to External Wireless Control
Control is performed via the included Dry Contact Controller (DRYLWE02). All information on usage and connection to switching contacts can be found in the DRYLWE02 manual.
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.
External Water Sensor
Socket on the power cable next to the motor. Remove the blue/white protective pad, plug in the sensor (press firmly for a waterproof connection).
When water is detected:
- Flood alarm is triggered, LED flashes red
- Depending on configuration: valve closes automatically or stays open
- Clear alarm: Hold button for 2 seconds
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.
