I. Overview of Imported Electric Three-Way Ball Valves

The German LIK brand's imported electric three-way ball valves can be divided into L-type and T-type. The L-type three-way ball valve is used for switching the flow direction of the medium, enabling the connection of two mutually perpendicular channels. The T-type three-way ball valve is used for medium diversion, convergence, and flow direction switching. The T-type three-way can interconnect three channels or connect two of them.

II. Performance of Imported Electric Three-Way Ball Valves

1. Simple structure, compact size, and lightweight.
2. Tight and reliable, with sealing surface materials that typically offer excellent sealing performance; some products can also be widely used in vacuum systems.
3. Suitable for remote control, easy to operate, and quick to open and close.
4. Easy maintenance; the ball valve structure is simple, and the sealing rings are generally movable, making disassembly and replacement relatively straightforward.
5. When fully open or fully closed, the sealing surfaces of the ball and valve seat are isolated from the medium, preventing erosion of the valve sealing surfaces during medium flow.
6. Wide range of applications, with diameters ranging from a few millimeters to several meters, suitable for use from high vacuum to high pressure.

III. Structural Features of Imported Electric Three-Way Ball Valves

1. The bore size matches the pipeline, preventing sediment accumulation.
2. The inner wall of the flow channel is polished to ensure smooth and unobstructed flow.
3. Fully enclosed sealing materials are used, with no dead corners, making cleaning easy.
4. Multi-purpose valve; any port can be used as an inlet without leakage. The three-way valve can be designed as either an L-type or T-type port.

V. Precautions for Imported Electric Three-Way Ball Valves

1. Before installation, ensure there are no impurities in the pipeline to avoid damaging the ball valve sealing surfaces.
2. Install the ball valve correctly according to the product manual, paying attention to the installation direction and connection method.
3. Regularly inspect and maintain the ball valve to ensure its proper operation.
4. Select appropriate ball valve materials and sealing materials based on the characteristics of the medium and usage conditions.
5. When operating the electric actuator, follow relevant operating procedures to avoid misuse.
6. Pay attention to the working pressure and temperature range of the ball valve to avoid overpressure or overtemperature use.
7. If leakage or other abnormalities are detected, stop use immediately and perform repairs or replacements.
