Brake valveHCZF*-15

HCZF*-15 brake valve is used in the brake system of forklift truck. The brake valve is equipped with a diverter valve, so that the constant flow for the forklift steering system can be diverted out of a very small part of the flow (500~700mL/min) through the brake valve for the brake valve to work. The brake valve is controlled by the foot pedal. When the pedal is pressed, the pedal stroke is transferred to the piston rod of the brake valve by the push rod, and under the action of the pressure reducing valve in the brake valve, a certain pressure is generated on the piston rod side of the piston to form a booster, and the hydraulic oil in the piston cavity enters the brake through the safety valve to realize the braking of the forklift truck, and the pedal force is linearly proportional to the output pressure of the brake valve with a better foot feeling. When the pedal is released, the high-pressure oil in the brake returns to the piston cavity through the safety valve, and at the same time, the replenishment valve in the brake valve opens under negative pressure to replenish the oil to the piston cavity to ensure that there is enough hydraulic oil in the piston cavity when braking again, so that it can be braked even in the case of engine shutdown. In addition, the safety valve at the outlet of the piston chamber keeps the fluid from flowing back completely when the brake is unloaded and maintains a certain pressure, which ensures rapid filling and more reliable braking when the brake is applied again.
