HCZF*-15 brake valve

特性说明：
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.

Shared Hydraulic System: The power brake valves share the hydraulic fluid source of the steering system to charge the accumulators and brake the valves; when the engine is off, the power brakes utilize the pressurized fluid stored in the accumulators to apply the brakes. Overload unloading: Accumulator built-in relief valve, automatic unloading after exceeding the set pressure Under Pressure Alarm: Accumulator built-in alarm, when the accumulator pressure is lower than the set pressure, the alarm alarm, prompting the operator to charge the accumulator liquid Full-featured: the combination of power brake valve and accumulator can well meet the braking function of forklift trucks in three working conditions: traveling, stopping and emergency stopping. Comfortable Foot Feeling: the pedal force is linearly proportional to the output pressure of the brake valve, which makes the foot feeling light and comfortable. Unloading safety valve: The use of E45E5-40211 safety valve can make the brake fluid will not flow back completely when unloading, to ensure that the brake is filled quickly and the brake is more reliable when braking again.

Multi-way directional valve

YCDC*-15

Discription of specification：
Built-in Priority Valve: The inlet body component has a priority valve that prioritizes flow to the steering system and does not provide steering flow when not steering. Lowering protection solenoid valve: only when this solenoid valve is opened, the lowering control operation is effective Unloading solenoid valve: only when this solenoid valve is open, the gantry lifts, tilts, and generator operation is effective. Built-in check valve: Each reversing body has a built-in check valve to prevent backflow of oil. Setting the valve stem self-locking: preventing the forklift gantry from vibrating due to the negative pressure inside the tilting cylinder, and locking the tilting cylinder when the engine is off, avoiding the tilting of the forklift gantry forward by mistake, which will cause a potential safety hazard. Setting double safety valves: main safety valve to control system pressure, shunt safety valve to ensure the normal working pressure of the steering system Additional valves: at both ends of the commutator, overload valves or make-up valves can be added according to requirements Valve body structure: piece structure, any combination within 1~10 links Stem center function: A, Z, O, Y, etc.

Specification：
Nominal pressure: 20MPa ; Nominal flow: 65L/min ; Stem stroke:7+7mm; Weight: 4.05+(3.1*n)Kg (n is the number of reversing body coupling)
