Sun Cartridge Valve PPHB-LBN High Flow Capacity Silver High Durability Cast Iron

Product Specification

Description:

The Sun Cartridge Valve PPHB-LBN is a pilot-operated pressure-reducing/relieving valve manufactured by Sun Hydraulics. This valve is designed to reduce high inlet pressure (port 2) to a constant reduced pressure at port 1 and provides full-flow relief from port 1 to tank (port 3). This design effectively manages pressure in hydraulic systems, ensuring stable operation under varying operating conditions. The PPHB-LBN valve's core advantage lies in its pilot-operated mechanism, which provides excellent pressure control, a low pressure rise vs. flow curve, high stability, and low hysteresis. Furthermore, the valve utilizes Sun's unique floating design, which allows the valve plug to float freely within the valve body, reducing the possibility of internal component seizure caused by excessive installation torque or machining errors. This floating design not only enhances valve reliability and durability but also facilitates cleaning and inspection without changing the valve's existing settings or disassembling any piping.

Applications:

Construction Machinery: In construction machinery such as excavators and cranes, PPHB-LBN valves are used to control pressure in hydraulic systems, ensuring stable operation under complex operating conditions.
Industrial Automation: In automated production lines and robotic systems, these valves precisely control the movement of hydraulic cylinders and motors, improving production efficiency and product quality.
Metallurgy and Heavy Machinery: In heavy equipment such as steel mills and rolling mills, PPHB-LBN valves withstand high pressures and high flows, ensuring long-term, stable operation.
Marine and Offshore Engineering: The corrosion resistance and high reliability of PPHB-LBN valves make them an ideal choice for ship hydraulic systems such as steering gear, cranes, and anchor winches.
Aerospace: In the aerospace sector, these valves are used in aircraft landing gear retraction and extension systems, flight control surface actuation systems, and other applications, meeting stringent requirements for precision and reliability.
 

Advantages:

High-Performance Pressure Control: The PPHB-LBN valve reduces high inlet pressures to a constant reduced pressure value, ensuring stable hydraulic system operation under varying operating conditions. This valve features a low pressure rise and flow curve, excellent stability, and low hysteresis.
Floating Design: The valve plug floats freely within the valve body, reducing the possibility of internal components seizing due to excessive installation torque or machining errors. The floating design allows for higher installation torques, ensuring the valve will not loosen or leak during actual use.
High Durability and Reliability: Internal working components are heat-treated for high resistance to wear, impact, and fatigue, ensuring a long service life. Each valve undergoes rigorous functional testing before shipment to ensure reliability and performance under various operating conditions.
Easy Maintenance and Cleaning: The floating design facilitates cleaning and inspection without changing existing valve settings or disassembling any piping.
Compact Design and High Flow Capacity: This valve integrates the functions of two valves into a single body and cavity, reducing material usage and creating a more compact and efficient system. The valve design provides a high flow capacity, reduces the effects of eccentricity, and distributes thread loads deep within the oil plate. Strong adaptability: PPHB-LBN valve is suitable for a variety of hydraulic systems and can adapt to different working pressure and flow requirements.
