Sun Cartridge Valve PPDB-LAN Flexibility And Compatibility Low Leakage High

Product Specification

Description:

The Sun Cartridge Valve PPDB-LAN is a pilot-operated pressure reducing/relieving valve manufactured by Sun Hydraulics. Its primary function is to reduce high main pressure at the inlet (port 2) to a constant reduced pressure at port 1, while providing full-flow pressure relief from port 1 to the tank (port 3). This design allows it to stably maintain the set pressure in the hydraulic system while providing reliable pressure relief if the pressure exceeds the set value. It can operate at up to 10 gallons per minute (approximately 40 liters per minute). The standard screw adjustment range is 100 to 3000 psi.
 

Applications:

Industrial hydraulic systems: In various industrial equipment, such as injection molding machines and hydraulic presses, the PPDB-LAN valve is used to control pressure in the hydraulic system, ensuring stable operation at the set pressure and improving production efficiency and product quality.
Construction machinery: In construction machinery such as excavators and cranes, this valve is used to control pressure in the hydraulic system, ensuring stability and safety under complex operating conditions. Metallurgy and Heavy Machinery: In heavy equipment such as steel mills and rolling mills, PPDB-LAN valves are used to control high-pressure hydraulic systems, ensuring stable operation under extreme operating conditions.
Testing and Simulation Equipment: In systems requiring high dynamic response, such as hydraulic test benches and flight simulators, PPDB-LAN valves provide stable hydraulic control to meet complex testing needs.
 

Advantages:

High Stability: The PPDB-LAN valve utilizes a pilot-operated design that stably maintains the set pressure, even at high reduced pressures. This design effectively reduces pressure fluctuations in hydraulic systems and improves overall system stability.
High Reliability: Sun Hydraulics' cartridge valve design offers significant reliability advantages. The free-floating design at the valve tail allows the precision-fitting working components to float within the valve body, reducing sensitivity to installation torque and preventing the possibility of seizure of internal moving parts. Furthermore, the valve's internal working components are heat-treated for high wear, impact, and fatigue resistance, ensuring a long service life.

Easy Installation and Maintenance: The PPDB-LAN valve's floating design allows for high installation torque, ensuring the valve will not loosen or leak during use. Furthermore, it can be cleaned or inspected without changing the valve's existing settings or disassembling piping. This design not only improves installation convenience but also reduces maintenance time and costs.
Flexibility and Compatibility: The PPDB-LAN valve's consistent porting provides greater design flexibility, reducing the need for manifolds. This flexibility enables the valve to be easily integrated into various hydraulic systems to meet the needs of a wide range of applications.
Protection: The PPDB-LAN valve features a full-flow pressure relief function, providing reliable pressure relief when pressure exceeds the set point, protecting other components in the hydraulic system from high-pressure damage.
Low Leakage: The valve's excellent sealing performance effectively reduces hydraulic oil leakage, improving overall system efficiency. Low leakage not only reduces energy waste but also reduces the risk of environmental pollution and equipment failure caused by hydraulic oil leakage.
