Sun Cartridge Valve CBGG-LKN Wide Application Low Leakage Silver Cast Iron Hose

Product Specification

Description:

The Sun Cartridge Valve CBGG-LKN is a high-performance, cartridge-type counterbalance valve manufactured by Sun Hydraulics in the United States. This valve is primarily used to control overloads in hydraulic systems, ensuring smooth and safe operation of hydraulic cylinders or motors under load. The CBGG-LKN valve utilizes a pilot-operated, hydraulically controlled, check valve design with a sealed pressure-operated valve, a steel seat, and an external port. The valve allows free flow from the valve port (port 2) to the load port (port 1), but blocks reverse flow. Pressure at the pilot port (port 3) opens the flow path from port 1 to port 2. This pilot pressure is directly proportional to the load pressure at port 1. Because the spring chamber is connected to the external port (port 4), the valve is unaffected by pressure at port 2. This design enables the CBGG-LKN valve to provide precise load control and reliable performance in hydraulic systems.

Applications:

Construction Machinery: In construction machinery such as excavators, cranes, and loaders, hydraulic cylinders and motors must operate under complex working conditions, making load control crucial. The CBGG-LKN valve ensures smooth operation of hydraulic cylinders under load, preventing equipment damage caused by excessive loads.
Industrial Automation: In industrial automation production lines, hydraulic systems are often used to drive equipment such as manipulators, hydraulic presses, and hydraulic shears. The CBGG-LKN valve provides high-precision load control, ensuring smooth manipulator movement during gripping, handling, and assembly.
Marine and Offshore Engineering: Ship hydraulic systems, such as steering gear, cranes, and anchor winches, must operate reliably in harsh marine environments. The high reliability and corrosion resistance of the CBGG-LKN valve make it an ideal choice for ship hydraulic systems.
Aerospace: In the aerospace sector, hydraulic systems are used in aircraft landing gear retraction and extension systems, flight control surface actuation systems, and other applications. The high performance and reliability of the CBGG-LKN valve meet the stringent precision and reliability requirements of these systems.

Advantages:

High-Precision Load Control: The GBGG-LKN valve utilizes a pilot-operated, hydraulically controlled, check valve design, enabling precise control of the load on a hydraulic cylinder or motor. The pressure at the pilot port opens the flow path from port 1 to port 2, and this pressure is directly proportional to the load pressure, ensuring precise load control. This design enables the valve to respond quickly to load changes, providing stable load control.
High Reliability: The valve's internal working components are heat-treated for high resistance to wear, impact, and fatigue, ensuring a long service life. Furthermore, the valve's floating design reduces the effects of installation torque on the valve's internal components, eliminating the possibility of internal components seizing due to improper installation. This design enhances valve reliability and stability, reducing maintenance costs.
Low Leakage: The CBGG-LKN valve exhibits very low leakage, generating only approximately 1 drop (0.07cc) per 4,000 actuations. This low leakage design not only improves system efficiency but also reduces hydraulic fluid waste and environmental pollution.

Hose Burst Protection: This valve provides hose burst protection, preventing loads from falling due to hydraulic system failures. This protection is crucial in hydraulic systems, especially in applications with heavy loads, as it effectively prevents equipment damage and accidents caused by hydraulic system failures.
Easy Installation and Maintenance: The CBGG-LKN valve utilizes a floating design, reducing the impact of installation torque on internal components and facilitating installation. Furthermore, cleaning and inspection of the valve do not require changing valve settings or disassembling any piping. This design simplifies valve maintenance, reducing downtime and maintenance costs.
Wide Application: This valve is suitable for a variety of hydraulic systems, including open and closed circuits. Its wide applicability enables it to meet the needs of diverse industries and applications.
