Sun Cartridge Valve LOHD-8DN Energy Saving High Efficiency Ong Service Life

Product Specification

Description:

The Sun Hydraulic Valve LOHD-8DN is a high-performance, cartridge-style logic valve manufactured by Sun Hydraulics. This valve is an unbalanced, air-to-open, bidirectional logic switching element with an integrated pilot control chamber. It is spring-biased closed and features a built-in shuttle valve, allowing the higher pressure in port 1 or port 2 to serve as the pilot source. This design enables the LOHD-8DN valve to quickly respond to pressure changes, providing precise hydraulic control. Key features of the LOHD-8DN valve are its fast response and high reliability. It responds to pressure changes on all ports, thus accounting for all pressure variations throughout the complete system operating cycle. Furthermore, the valve's floating design reduces the possibility of internal component seizure caused by excessive installation torque or bore/valve plug machining errors. This design not only improves valve durability but also simplifies cleaning and inspection, eliminating the need to modify the existing valve configuration or disassemble any piping.

Applications:

The LOHD-8DN valve is widely used in various fields due to its high performance and reliability:
Industrial Automation: In automated production lines, the LOHD-8DN valve controls the movement of hydraulic cylinders and motors, achieving precise positioning and speed control. For example, in equipment such as injection molding machines and hydraulic presses, the valve provides stable power, ensuring efficient operation.
Construction Machinery: In construction machinery such as excavators and cranes, the LOHD-8DN valve controls the movement of hydraulic actuators, such as telescopic boom extension and retraction, and slewing mechanism rotation. Its rapid response improves operational efficiency and precision.
Hydraulic Testing Equipment: In hydraulic test benches and simulation equipment, the LOHD-8DN valve provides highly dynamic hydraulic control to meet complex testing requirements.
Aerospace: In the aerospace industry, the LOHD-8DN valve is used in aircraft landing gear retraction and extension systems, flight control surface actuation systems, and other applications. Its high reliability and precise control capabilities meet the stringent precision and reliability requirements of these systems.

Advantages:

Fast Response and High Reliability: The LOHD-8DN valve features a direct-acting design, offering fast response and rapid switching in response to pressure changes. Its built-in shuttle valve automatically selects the higher pressure as the pilot source, further enhancing system responsiveness and reliability.
Pressure Response and Flexibility: The valve responds to pressure changes at all ports, meaning that pressure changes at any port throughout the system's operating cycle can cause the valve to switch state. This design provides exceptional flexibility, adapting to complex hydraulic system requirements.
Floating Design: The LOHD-8DN valve utilizes a floating design, reducing the possibility of internal components seizing due to excessive installation torque or machining errors in the socket/valve core. This design not only improves valve durability but also simplifies cleaning and inspection, eliminating the need to modify the existing valve configuration or disassemble any piping.
Various Pilot Control Options: The LOHD-8DN valve offers a variety of pilot control options, including electro-proportional, solenoid, pneumatic, and hydraulic. This diverse control method allows the valve to adapt to diverse application scenarios and control requirements. High Pressure Resistance and Durability: The LOHD-8DN valve can withstand pressures up to 5000 psi (350 bar), making it suitable for high-pressure hydraulic systems. Its internal working components are heat-treated for high resistance to wear, impact, and fatigue, ensuring a long service life.
Easy Maintenance and Cleaning: Thanks to its floating design, cleaning or inspecting the plug-in valve requires no changes to the valve's existing configuration or disassembly of any piping. This design significantly simplifies maintenance, reducing downtime and costs.
Compact Design and Installation Flexibility: The LOHD-8DN valve features a compact design and a variety of mounting options, allowing for easy integration into existing hydraulic systems. Its internal threaded connections make installation quick and easy while reducing overall system size.
