Sun Cartridge Valve PBFB-LBN Long Life Easy Cleaning And Inspection Durable Design Free-Float Design

Description:

The Sun Cartridge Valve PBFB-LBN is a pilot-operated pressure-reducing valve manufactured by Sun Hydraulics and part of the cartridge valve series. This valve is designed to reduce high-pressure hydraulic oil in hydraulic systems to the desired low pressure to meet the pressure requirements of various hydraulic circuits. Its primary function is to ensure stable operation of the hydraulic system by precisely controlling hydraulic oil pressure. The pilot valve controls the movement of the main valve core, achieving precise pressure regulation. This valve can adapt to varying operating pressure requirements. The pilot-operated pressure-reducing valve exhibits extremely low pressure/flow characteristic variation and high stability during operation. During pressure regulation, the valve exhibits low hysteresis, enabling rapid response to pressure changes.
 

Applications:

Construction Machinery: In construction machinery such as excavators, cranes, and loaders, this valve is used to control pressure in the hydraulic system, ensuring stable operation under various operating conditions. For example, during the extension and rotation of a crane's boom, the PBFB-LBN precisely controls hydraulic oil pressure, preventing equipment failure caused by excessive or insufficient pressure. Industrial Automation: In automated production lines, hydraulic systems are often used to drive equipment such as manipulators, hydraulic presses, and hydraulic shears. The PBFB-LBN precisely controls the pressure in hydraulic cylinders or motors, ensuring efficient operation.
Marine and Offshore Engineering: Ship hydraulic systems, such as steering gear, cranes, and anchor winches, must operate reliably in harsh marine environments. The PBFB-LBN's high reliability and corrosion resistance 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 more. The PBFB-LBN's high performance and reliability meet the stringent precision and reliability requirements of these systems.
 

Advantages:

Precise Pressure Regulation: The PBFB-LBN achieves precise pressure regulation by controlling the movement of the main valve spool via a pilot valve.
Low Hysteresis: During pressure regulation, the valve exhibits low hysteresis, enabling rapid response to pressure changes.
Stable Performance: Pilot-operated pressure reducing valves exhibit minimal fluctuations in pressure/flow characteristics during operation, resulting in high stability. Low Pressure Gradient: This valve maintains stable pressure even with large flow rate fluctuations.
Durable Design: Utilizing high-quality materials and advanced manufacturing processes, it offers excellent wear and contamination resistance.
Free-Float Design: The free-floating design at the valve tail reduces the effects of installation torque on the valve core, preventing the possibility of internal components seizing.
Long Life: Internal working components are heat-treated for wear, impact, and fatigue resistance, ensuring a long service life.
Various Mounting Options: A variety of mounting options are available for easy integration into existing hydraulic systems.
Easy Maintenance: The simple design facilitates maintenance, reducing downtime and costs.
Easy Cleaning and Inspection: The plug-in valve can be cleaned or inspected without changing the existing valve settings or disassembling piping.
