Manual Hydraulic Rotary Valve

 Main FunctionThe function of the rotary valve type reversing valve in the hydraulic system is to change the relative position with the valve body by rotating the cylindrical valve core, and to connect or close the oil circuit to realize the reversal of the hydraulic actuator. Since the valve core needs to be rotated when operating the valve, this valve is generally controlled by manual or motor operation. Similar to the slide valve type reversing valve. The rotary valve type reversing valve also has two-position valves (two-way, four-way, five-way), three-position valves (four-way, five-way) and other common types.    Working PrincipleTake the three-position four-way rotary valve shown in Figure 4-61 as an example to explain the working principle of the rotary valve type reversing valve. The three-position four-way rotary valve consists of the main components such as the valve body 1, the valve core 2 and the operating handle (not shown in the figure). There are four CP…
