Installation Instructions
Compatibility and Cleaning Requirements
This valve is compatible with Siemens drivers. Before installation, ensure that the pipe is clean and free of oxide scale, metal flakes and other debris.
Installation Direction and Connection Notes
The valve stem is in the closing direction when it is downward; the pipe must be concentric and vibration-free when connected, and the water flow direction should be consistent with the valve body marking.
Driver Installation Requirements
When the driver is installed vertically on the valve body, avoid it being located below the valve body, and reserve enough space for maintenance (such as disassembling the driver).
Maintenance Notes
When maintaining the valve, the power supply must be cut off and the system must be pressure-free to avoid operational risks.
