The manual slide valve mainly relies on the sliding of the spool within the valve body to achieve control of the fluid. When operating the handle to slide the spool to the left or right, the flow passage area between the spool and the valve body will change. Taking a common two-position three-way manual slide valve as an example, when the spool is in one position, the inlet can be connected to one outlet, and the other outlet is closed; when the spool slides to another position, the inlet is connected to the other outlet, and the originally connected outlet becomes closed, thereby realizing the switching of the fluid flow direction. In some manual slide valves with adjustable flow rates, by precisely controlling the sliding distance of the spool, the flow passage area can be continuously changed, and then the precise adjustment of the fluid flow rate can be achieved.
