Sun Cartridge Valve NCFB-LCN Easy Maintenance Non-Leakage Cast Iron Design Bidirectional Flow Design

Description:

The Sun Cartridge Valve NCFB-LCN is a high-performance hydraulic cartridge needle valve with a reverse flow check function. It is widely used in hydraulic systems requiring precise flow control and reliable operation. The valve's design allows for infinite adjustment from fully closed to maximum aperture, ensuring stable flow control under various operating conditions. The valve primarily consists of a valve body, a valve seat, and a cartridge valve core. The valve body and seat form a flow path through which the cartridge valve core moves, controlling the flow of fluid. When external pressure acts on the valve core, it overcomes the resistance of a spring or other retaining device and lifts from the seat, allowing fluid flow. When external pressure is removed or reverse pressure is applied, the valve core returns to its original position, supported by a spring or other mechanism, closing the flow path. The valve also features a regulating mechanism that allows the valve core's opening to be controlled by adjusting external pressure or other parameters, thereby adjusting fluid flow or pressure.

Applications:

Industrial Automation: In industrial automation production lines, hydraulic systems are often used to drive equipment such as robotic arms, hydraulic punches, and hydraulic shears. The NCFB-LCN valve seamlessly integrates with automated control systems, precisely controlling the movement of hydraulic cylinders or motors by receiving electrical signals from a PLC or other controller.
Construction Machinery: In the hydraulic systems of equipment such as excavators, loaders, and cranes, the NCFB-LCN valve controls the movement of hydraulic cylinders and motors, enabling precise operation.
Metallurgy and Heavy Machinery: In heavy equipment such as steel mills, rolling mills, and presses, this valve controls high-pressure hydraulic systems, enabling precise control of heavy-duty equipment. Its high pressure resistance and stability make it suitable for use in extreme operating conditions.
Testing and Simulation Equipment: In systems requiring high dynamic response, such as hydraulic test benches, flight simulators, and automotive test equipment, this valve provides high-frequency, high-precision hydraulic control to meet complex testing requirements.

Advantages:

High-Precision Control: The NCFB-LCN valve utilizes a needle valve design, enabling infinite adjustment from fully closed to maximum orifice, ensuring precise flow control under various operating conditions. Its sharp-edged orifice minimizes flow variations caused by viscosity changes.
Fast Response: Thanks to its pilot-operated control structure, the valve offers fast response, making it suitable for applications requiring frequent starts and stops or rapid directional changes. Its dynamic response characteristics meet high-frequency control requirements, improving overall system efficiency.
Energy Efficiency: By precisely controlling oil flow, the valve avoids unnecessary energy loss. For example, under low-load conditions, the system automatically reduces flow output, reducing energy waste and achieving energy-efficient operation.
High Reliability: Utilizing high-quality materials and advanced manufacturing processes, the valve exhibits excellent wear resistance and contamination resistance. Its rational design allows for easy maintenance and a long service life, making it suitable for long-term continuous operation.
Compatibility and Modularity: The NCFB-LCN valve seamlessly integrates with Sun Hydraulics components such as amplifiers, sensors, and controllers to create a complete electro-hydraulic proportional control system. Its modular design also facilitates system expansion and maintenance.
Floating Design: The valve's floating design allows it to float freely within the valve body, reducing sensitivity to installation torque and preventing the possibility of internal moving components seizing. This design not only improves valve reliability but also allows for higher installation torque, ensuring the valve will not loosen or leak during operation.
Easy Maintenance: Cleaning or inspecting the cartridge valve does not require changing the valve's settings or disassembling any piping. This design significantly simplifies maintenance, reducing downtime and costs.
Protective Function: The valve's main stage orifice is protected by a 150-micron stainless steel screen to extend product life. This protection enhances valve durability and reliability, reducing malfunctions caused by impurities.
Non-Leakage Design: When the adjusting screw is in the closed position, the valve is leak-free. This design ensures a tight seal in the hydraulic system, reducing hydraulic oil waste and environmental pollution.
Bidirectional Flow Design: The valve's flow path is bidirectional, but the preferred path is from port 1 to port 2, enabling interchangeability with other flow control valves. This design provides greater flexibility and facilitates system design and maintenance.
