Sun Cartridge Valve LODC-XDN Low Noise And Vibration Fast Response High

Product Specification

Description:

The Sun Hydraulic Valve LODC-XDN is a pilot-operated logic valve manufactured by Sun Hydraulics and part of the cartridge valve series. It is a pilot-to-close, spring-biased, unbalanced poppet-type logic element widely used in hydraulic systems to control fluid flow and pressure. The valve uses pilot pressure to control the opening and closing of the spool. When the pressure at the pilot port (port 3) plus the spring force exceeds the pressure at the working port (port 1 or port 2), the valve remains closed; otherwise, the valve opens. The LODC-XDN features a floating design, minimizing the effects of installation torque on internal components and preventing sticking caused by machining errors.
 

Applications:

The LODC-XDN logic valve, with its high performance and versatility, is widely used in various industries and fields:
Construction Machinery: Used in the hydraulic systems of equipment such as excavators, loaders, and cranes, it controls the movement of hydraulic cylinders and hydraulic motors, achieving precise directional and speed control.
Industrial Automation: Used in automated production lines to control the reciprocating motion of hydraulic cylinders, enabling operations such as material handling and assembly. Steel and Metallurgy: Used in rolling mills, presses, and other equipment to control high-pressure hydraulic systems, ensuring stable operation.
Petrochemical: Used in oil drilling and chemical equipment to control complex hydraulic systems, ensuring safe and reliable operation.
Marine and Offshore Engineering: Used in ship hydraulic steering gear, cranes, and other equipment, ensuring stable operation in harsh marine environments.
Aerospace: Used in flight simulators and test equipment to control high-precision hydraulic systems, simulating real-world operating conditions.
 

Advantages:

High-Precision Control: The LODC-XDN precisely controls the opening and closing of the valve spool using pilot pressure, enabling high-precision control of hydraulic systems. The valve is sensitive to pressure changes at all ports and responds quickly to system pressure changes, ensuring accurate control.
Fast Response: Due to its pilot-operated design, the LODC-XDN offers fast response, making it suitable for hydraulic systems requiring rapid directional switching. Its design allows for rapid switching under high pressure, reducing system latency.
High Reliability: The floating structure reduces the impact of installation torque on internal components, preventing sticking caused by machining errors. The valve body is constructed of high-strength materials, offering excellent corrosion and fatigue resistance and a long service life.
Versatility: The LODC-XDN can achieve a variety of control functions, such as directional control and pressure control, by replacing different pilot control valves and cover plates. The valve can be combined with other hydraulic components (such as solenoid valves and pressure valves), simplifying system design.
Easy Integration and Maintenance: The cartridge valve design allows the LODC-XDN to be easily integrated into existing hydraulic systems, reducing installation space. The floating structure allows for high installation torque, ensuring a secure installation of the valve body and preventing loosening and oil leakage.
Low Noise and Vibration: Because the valve body is located within the manifold, the LODC-XDN operates with low noise and vibration, improving system stability. This design also reduces the risk of oil leaks caused by piping installation.
