Product operation manual

Thank you for choosing our powerful excavator hydraulic control valve products! In order to ensure that you can correctly operate the hydraulic control valve during use and ensure the efficient operation of the hydraulic system, we have prepared this operation manual for you. Please read this manual carefully before use, and perform operation and maintenance according to the guidance.

1. Hydraulic control valve overview

The excavator hydraulic control valve is the key component of the excavator hydraulic system, which is responsible for controlling the hydraulic flow direction and pressure, adjusting the working state of the hydraulic system, so as to achieve the precise control of various actions of the excavator.

2. Safety precautions

Before operating a hydraulic control valve, be sure to follow the following safety precautions:

Make sure the excavator is in a safe and stable working condition and stop the engine.
When inspecting and maintaining the hydraulic control valve, close the main valve of the hydraulic system and ensure that the hydraulic pressure has been released.
When operating the hydraulic control valve, do not touch the hydraulic valve or its nearby moving parts with your hands to avoid accidental injury.
When operating hydraulic control valves, focus on the job and avoid distraction or fatigue.
3. Operation method of hydraulic control valve

Before starting the excavator, ensure that the following steps have been completed:

Turn on the main power supply of the excavator and confirm that the hydraulic oil level is within the normal range.
Check the hydraulic oil temperature to ensure that it is within the normal operating temperature range (usually -20°C to +80°C).
Start the engine and let it warm for a period of time until the hydraulic oil temperature rises to the normal working range.
Operating hydraulic control valve:

According to the actual work requirements of the excavator, the control rod or button on the hydraulic control valve is operated to control the hydraulic flow direction and pressure.
In the operation process, pay attention to the working state of the hydraulic system, such as hydraulic pressure, flow and other parameters, to ensure that it operates within the normal range.
If you find that the hydraulic control valve is abnormal or the hydraulic system has a problem, please stop using immediately, and check and repair.
4. Maintenance method of hydraulic control valve

Regular maintenance of the hydraulic control valve can ensure its normal operation and extend its service life. Here are some suggested maintenance methods:

Check the seals and connectors of the hydraulic control valve regularly, and replace them in time if they are damaged.
Clean the hydraulic control valve regularly to avoid sediment and debris entering the valve body, affecting the flexibility of the valve.
Pay attention to the cleaning and replacement of hydraulic oil to ensure that the hydraulic oil in the hydraulic system meets the specified quality standards.
Check and adjust the hydraulic control valve regularly to ensure that it operates in normal working condition.
Thank you for reading our Excavator Hydraulic control Valve operation manual. If you encounter any problems in the process of use, please contact us in time, we will be happy to provide you with technical support and service.

Wish your excavator work smoothly, safely and efficiently!

Product features and working principle

Excavator hydraulic distribution valve is an important hydraulic control element in excavator and other construction machinery, it plays an important role in distributing and controlling hydraulic oil flow.
Product features:

Efficient and accurate hydraulic control: The excavator hydraulic distribution valve adopts advanced hydraulic control technology, which can achieve efficient and accurate hydraulic control to ensure the smooth operation of the machinery and the maximum work efficiency.
A variety of control methods: The hydraulic distribution valve has a variety of control methods, including proportional control, electromagnetic control, etc., to meet the operating needs of different working conditions, to provide more flexible and diverse operating methods.
Wear resistance and corrosion resistance: The distribution valve adopts high-quality materials and advanced surface treatment technology, with good wear resistance and corrosion resistance, and can operate stably in harsh working environments for a long time.
Compact structure, small size: compact product design, occupy a small space, is conducive to the overall layout and structure optimization of construction machinery, improve the mobility and flexibility of machinery.
Safe and reliable: The hydraulic distribution valve is equipped with perfect safety protection devices, such as overload protection, overpressure protection, etc., to ensure the safety and reliability of operators and equipment.
How it works:

The hydraulic distribution valve of excavator regulates the oil flow distribution in the hydraulic system by controlling the movement of the valve core. When the operator controls the joystick, the spool moves accordingly, changing the oil circuit in the valve, thereby controlling the flow direction and pressure of the hydraulic oil flow. For example, on the actuator of the arm, bucket rod and bucket of the excavator, the distribution valve realizes the expansion and expansion of the hydraulic cylinder and the opening and closing of the bucket by controlling the entry and exit of the oil flow.

There are many kinds of control methods of hydraulic distribution valve, among which proportional control is a common technology. Proportional control is to adjust the size of the cross-sectional area of the oil circuit by changing the position of the valve core, so as to achieve accurate control of the hydraulic oil flow. This control mode can be adjusted continuously and smoothly according to the operation requirements, making the action of construction machinery more flexible and smooth.

In general, the excavator hydraulic distribution valve plays a vital role in the hydraulic system of construction machinery, and realizes the efficient operation and accurate operation of machinery through accurate hydraulic control. At the same time, its compact structure, safe and reliable characteristics also provide a guarantee for the design and use of construction machinery.

Product application range

Excavator hydraulic distribution valve is a key hydraulic control device, widely used in all kinds of excavators and construction machinery. Its excellent hydraulic control performance and flexible design make it play an important role in the following areas:

Construction site: excavator hydraulic distribution valve is an indispensable part of the construction site. It can control the movement of the excavator's arm, bucket rod, bucket and other actuator, realize the excavation, loading, unloading and other work, and greatly improve the working efficiency and flexibility of construction machinery.
Mining: In mining operations, excavator hydraulic distribution valves play a key role. It can realize the complex actions of excavators, such as unloading, cleaning gravel, blasting excavation, etc., to help improve the efficiency of ore mining and reduce manual labor intensity.
Urban construction: excavator hydraulic distribution valve plays an indispensable role in urban construction. It is widely used in infrastructure construction, road construction, bridge repair and other projects, providing strong support for urban development and improvement.
In the agricultural field, excavator hydraulic distribution valves are often used in agricultural excavators and loaders. It can help farmers to achieve land consolidation, water irrigation, stacking and other operations, improve agricultural production efficiency.
