Multi channel valve with multiple channelsIt is a valve with multiple working positions and multiple fluid channels, widely used in analytical instruments such as high-performance liquid chromatography, protein purification preparation, and industrial automation.

Position ": refers to the working position of the valve core of the directional valve. 'Tong' refers to the number of interfaces on the valve body of the directional valve.

Working Principle:

　　Multi channel valve with multiple channelsBy changing the position of the valve core, different fluid channels can be opened or closed to achieve fluid conduction, cutoff, or reversal. The working principle of this valve is based on the principle of pressure difference in fluid mechanics. When the valve core moves, the opening or closing of different flow channels will change the direction and flow rate of the fluid.

Structural characteristics:

1. Multi position design: The valve core has multiple working positions, each corresponding to a different fluid flow direction and channel combination.

2. Multi channel design: The valve body has multiple interfaces that can be connected to different pipelines in the system to achieve complex fluid control.

3. High precision and reliability: Multi position multi-channel valves typically use high-precision materials and advanced manufacturing processes to ensure valve sealing and reliability.

Advantage:

1. High integration: Combining multiple valves into one multi-channel valve body saves space.

2. Reduce residue: The significant reduction of residual media in the fluid system enhances the overall performance of the system.

3. Easy to maintain: Multi channel valves are concentrated in the process section, making them easier to clean and repair.

4. Reduce leakage risk: By reducing the number of accessories and welding joints, potential leakage points have been minimized.
