Description

Technical Field

[0002] The slide valve is a key valve device widely used in industrial fluid control. Its unique structural design primarily consists of a valve seat, a slide, and a drive mechanism. The valve seat has a specific flow channel opening, and the slide, driven by the drive mechanism, slides back and forth across the valve seat, opening and closing the fluid channel and regulating flow. During operation, when the slide is fully open, fluid flows smoothly through the valve seat channel with minimal resistance. As the slide gradually closes, the flow channel area decreases, reducing flow until it is completely shut off.
