Kobelco sk210 valve

Types of Kobelco SK210 valves

For every engine, the Kobelco SK210 valve is an imperative part that controls the flow of gases in and out of the engine cylinder. The valve assembly may consist of the valve itself and some other sub-components like valve springs, retainers, seals, etc. The Kobelco valve operator comprises the valve seat and the valve spindle. The valve seat is the part of the valve where it meets the seat, and it is usually made of a cast iron material. The valve operator is the part connected to the motor that opens or closes the valve. It is usually made of a metal material such as stainless steel that can handle diverse temperatures.

The main types of valves include:

• D-type valve: In this type of valve, the exhaust gases are let out from the engine by the downward movement of the valve. Simultaneously, the inlet of the air or fuel mixture occurs when the valve moves upward. The D-valve resembles a letter D.
• S-type valve: The functioning of the S-type valve is the same as the D-type valve. But in this case, the valve's movement resembles the letter S. The S-type valve is usually used in high-performance engines.
• F-type valve: The F-type valve shows the pathway of the letter F. This type of valve works the same way as the D and S-type valves. However, the F-type valve is usually found in older model engines. The F-valves are often replaced by D-valves due to technological advancements.

Components of a Kobelco valve:

The Kobelco valve assembly has many components that work together to ensure that the valve works seamlessly. Here are some parts of the valve assembly:

• Valve head: The valve head is considered the ‘top’ part of the valve. It is the component that seals the engine cylinder. The valve seat is usually a circular region.
• Stem: The valve stem is a long component that connects the valve head to the actuator. The actuator is connected to the engine itself.
• Retainer: The retainer holds the valve spring in place to prevent it from moving out of its position.
• Seat: The seat is where the valve head sits. It provides a covering for the engine cylinder so that the gas does not escape.
• Guide: The guide helps to align the valve within the seating area. It helps the valve to move up and down easily.

Every component in the valve assembly has its respective function. The mismatch or wrong installation of the valve can lead to the engine becoming non-functional or having sub-par performance.

Kobelco SK210 valve specification & maintenance

The Kobelco SK210 valve specifications are as follows.

• Appication: This valve applies to Kobelco SK210/8, SK210/9, and other Kobelco models.
• Product Dimensions: The product dimensions are approximate 3.2*3.2*1.9 m with a weight of about 5 kg. This size suits the structures of certain excavators.
• Material: The valve body is made of iron, which is resistant to high pressure and temperature. The valve core is made of stainless steel to resist corrosion. Furthermore, stainless steel can also withstand extreme temperatures, giving it flexibility for various applications.
• Working principle: The working principle of this hydraulic valve is to control the flow of hydraulic oil. Hydraulic valves often have two-part structures. The bottom part is the valve body, while the top part is the valve core. When the valve works, the oil enters from the valve body, passing through the valve core. Then the oil is released to the engine. By changing the position of the valve core, the oil flow and pressure are controlled, which influence the excavator’s functions.

The valve is a critical component that needs regular maintenance to ensure it operates correctly. Equipment operators should regularly check the valve for any signs of damage or wear and tear, such as cracks or leaks. They should also inspect the valve seats and the cork for any buildup of debris or dirt that could affect its performance. If there are any signs of damage, they should be repair service immediately to avoid any potential hydraulic system failure. The hydraulic system is crucial for the proper operation of an excavator.

In addition to regular inspection and cleaning, the valve should be lubricated periodically to ensure smooth operation and minimize wear. Follow the manufacturer’s instructions on the type and amount of lubricant to be used. Proper adjustment of the valve is also essential to maintain its performance and prolong its lifespan. The valve should be carefully adjusted to the specified pressure settings as advised by the manufacturer. This enables the valve to function optimally and help to prevent premature wear and damage.

Scenarios

The Kobelco SK210 valve comes with different models, each tailored for a specific task.

• Excavation Projects: The Kobelco hydraulic valve controls the flow of oil in the hydraulic cylinder, which helps to allow the bucket to open, close, and dig into the earth. The valve is crucial for oil regulation so that the cylinder can smoothly carry out its function of rotating, extending, retracting, and digging.
• Quarrying and Mining Operations: Valve controls the flow of hydraulic oil to the arm and bucket cylinders. This governs the movement of the excavator's arm and bucket, which are often tasked with digging, scooping, and transferring rock or soil materials. Proper hydraulic function is essential for the excavator to efficiently execute its duties in quarrying and mining operations.
• Heavy-Duty Excavation: In a demolition project, the Kobelco PSV (Pressure Switch Valve) may serve several functions. It may be responsible for monitoring and regulating the pressure within the hydraulic system of the excavator. By controlling the pressure, it ensures that the hydraulic functions, such as arm movements and hydraulic fluid circulation, work smoothly and efficiently. Additionally, the PSV may play a protective role by preventing the hydraulic system from experiencing excessive pressure. This helps safeguard both the excavator and the structures involved in the demolition.
• Construction and Earthmoving: The Kobelco SK210 Flow Control Valve regulates the excavator's movement by controlling the oil flow to the hydraulic motor and cylinder. Its function is to maintain a steady and ideal speed for the hydraulic motor and piston, facilitating the smooth and precise movement of the excavator in construction tasks like digging, trenching, and earthmoving.
• Road Construction: In land reclamation projects, the Kobelco swing valve holds an essential function. This device regulates the hydraulic oil flow to the motor responsible for swinging operations. Thanks to the swift movement of the excavator, operators can efficiently rearrange soil, rocks, and other materials to create new land areas.

How to choose Kobelco SK210 valves

Business buyers searching for valve options for their machinery should focus on the selection criteria outlined below.

• Machinery compatibility

Business buyers should ensure that the valves purchased are compatible with the machinery in which they will be installed. The requirements of the valve function done by the valve should be considered to ensure compatibility.
