ZG Series High-Pressure Motorized Rotary Valve 42 MPa (CAT#: STEM-BC-0444-ZJF)

The ZG series includes multi-channel selection valves, column position valves, and injection valves for high-pressure fluid path switching. It is designed for high-reliability operation with maximum working pressure above 40 MPa. The valves can be used in acid, alkali, and salt media environments. Typical applications include high-performance liquid chromatography and other high-pressure fluid switching workflows. Valve head and rotor material options support corrosion resistance and mechanical durability. High-precision encoder closed-loop control supports accurate positioning. Multiple communication interfaces support integration with automated systems. The series is suitable for demanding high-pressure analytical and preparative systems.
