OBV/HXQ* Dynamic Braking System

OBV/HXQ* Dynamic Braking System

OBV-L25E power brake valve and HXQ accumulator are used in the braking system of 5~10T forklift. When the engine is running, the brake valve is used to brake the forklift and fill the accumulator. When the engine is off The brake is realized by the foot brake brake valve using the pressure oil stored in the accumulator for the brake of the forklift. The brake valve is operated by the foot, and the pedaling force is linearly proportional to the output pressure of the brake valve, and the foot feel is good. The accumulator is provided with an alarm switch connected to the alarm. When the brake pressure is lower than the brake pressure, the alarm alarms, prompting the operator to fill the accumulator and ensure that the accumulator has sufficient pressure oil for braking. The combination of OBV-L25E dynamic brake valve and HXQ accumulator can well meet the braking function of the forklift under the three conditions of driving, parking and emergency parking, and it is reliable and widely used in hydraulic engineering of forklifts and other construction machinery. Braking System. E45E5-40211 safety valve is used together with the dynamic brake valve to prevent the oil from completely returning when the brake is unloaded, ensuring quick filling and more reliable braking when braking again.
★ Shared hydraulic system: The dynamic brake valve shares the hydraulic oil source of the steering system, and charges the accumulator and the brake valve. When the engine is off, the dynamic brake valve uses the pressure oil stored in the accumulator. brake
★ Overload unloading: accumulator built-in relief valve, automatic unloading after exceeding the set pressure
★ Undervoltage alarm: The accumulator has built-in alarm. When the accumulator pressure is lower than the set pressure, the alarm will alarm and prompt the operator to fill the accumulator.
★ Full-featured: The combination of dynamic brake valve and accumulator can well meet the brake function of the forklift under the three conditions of driving, parking and emergency parking.
★ Comfortable foot feeling: The pedaling force is linearly proportional to the brake valve output pressure, and the foot feels light and comfortable.
★ Unloading safety valve: The E45E5-40211 safety valve can be used together to prevent the oil from completely returning when the brake is unloaded, ensuring quick filling and more reliable braking when braking again.
