The opening and closing of the control valve can control the opening and closing of the brake. This valve group is used for the cylinder or motor to achieve the synchronous operation of two cylinders or motors under the condition of a single oil source. It is mainly used in occasions where the actuator has high requirements for speed synchronization during operation.
