When designing the pneumatic solenoid valve braking or locking circuit, the middle position function of CKD five-way solenoid valve slide valve can use a braking circuit to make the active working mechanism stop in any desired position, and prevent it from moving after stopping by external influence. The easiest way is to use a reversing valve to brake. For example, slide valves can be M or O type reversing valves. After returning to the neutral position, the oil inlet and oil return loop can be cut off to make the actuator stop the movement quickly. The hydraulic cylinder loaded into the arm is a brake oil circuit composed of m-type reversing valve with neutral function. It can lift the bucket to a high position and lower it to a low position under the action of moving arm force, automatic limit and braking. The oil return limit valves (M and H four-way directional valves) shown in the drawing are positioned with steel balls. The bucket moves to the limit point, touches the switch, the two solenoid valve is reversed, the compressed air is connected to the positioning steel ball pressure back into the groove, so that the return limit valve is restored to its original position under the action of the spring. Float using h - and Y-type reversals. For example, when the rotary mechanism of hydraulic crane rotates under the action of load, if the brake is too urgent, the inertia force will cause a great impact on the hydraulic.
