Excavator electric pilot control valve handle

In the wave of intelligent transformation of construction machinery, the excavator electric pilot control valve handle has become the focus of industry attention with its precise functional positioning, wide scene adaptability and outstanding technical characteristics. This innovative component that integrates electronic control and mechanical operation is providing efficient solutions for engineering operations under different working conditions through all-round performance optimization.

Stable power supply to ensure reliable operation of equipment

In terms of power supply, this control valve handle has excellent adaptability. Its power supply voltage range is 10-32VDC, and it can work stably in a variety of power supply environments, whether in unstable working conditions of temporary power supply in the field or in conventional scenarios with standard power supply configuration, it can ensure the normal operation of the equipment. At the same time, its low current consumption characteristics are very outstanding, only 100mA or less, which greatly reduces the energy consumption of the equipment and improves energy utilization efficiency. The pulse current is limited to 10A or less, which effectively avoids damage to the equipment caused by excessive current shock and ensures the safety and stability of the entire electrical system.

Efficient signal transmission for precise control

The signal output part is a highlight of this product. Adopting CAN (SAE J1939) EJM1 communication protocol, the source address is set to 249, the communication rate is up to 250kbps, and with a sampling period of 10ms, the operation instructions can be quickly and accurately transmitted to the excavator control system. This allows every action of the operator to be fed back to the equipment in a timely and accurate manner, achieving millimeter-level operation accuracy. The output accuracy is also excellent under different temperature environments. In an environment of -10 – +50°C, the medium accuracy can reach ±2%, and in an environment of -40 – +75°C, it can also be maintained at around ±3%, ensuring that the equipment can perform tasks stably and accurately in various complex environments.

Precision mechanical parameters, both durability and comfort

From the perspective of mechanical performance parameters, the control valve handle also performs well. Its hysteresis is controlled at ±1.6% or less, and the mechanical median deviation is 0.5° or less, which makes the handle operation feel smooth and responsive, effectively reducing operating errors and improving the comfort and accuracy of operation. The service temperature range is -40-75°C, which can adapt to various extreme environments from cold polar regions to hot deserts, greatly expanding the application scenarios of the equipment. The maximum operating torque is 226N/m, which ensures that the handle is durable enough to withstand high-intensity use while ensuring reasonable operating force.

Intelligent switch instructions, optimized operating experience

In terms of switch instructions, the product has also been carefully designed. The rated voltage and current are divided into two specifications: DC30V/3A (resistance load) and DC30V/1A (resistance load). The minimum borrowing capacity is DC5V/160mA and DC30V/26mA. The operating capacity and operating force are also reasonably set according to different switches, such as switches 1 and 3 are 1mm/4N, and switch 2 is 1mm/6N. These parameters make the switch operation both sensitive and labor-saving, further improving the operator’s experience. At the same time, its service temperature is also – 40 – 75°C, ensuring the stability and reliability of the switch function in various environments.

This excavator electric pilot control valve handle has excellent parameter performance in power supply, signal transmission, mechanical performance and switch instructions, which undoubtedly provides a solid guarantee for the intelligent and precise operation of the excavator. With its gradual promotion and application in the market, it will surely promote the construction machinery industry to a higher level and bring higher efficiency and quality improvement to various engineering construction projects.
