PPDBLWN is a high-performance hydraulic threaded cartridge valve which is mainly used to realize the control of force, speed and motion. This product is used in a wide range of applications such as mobile and industrial machinery and equipment. Here are some more details about SUN PPDBLWN:

Product Features
1. Functions and Applications The SUN PPDBLWN is a pilot operated pressure reducing/relieving valve capable of reducing the high main pressure at the inlet (port 2) to a constant reduced pressure at port 1 with full flow relief from port 1 to the tank (port 3). This design makes it possible to effectively control the pressure in the hydraulic system to ensure the stable operation of the system.
2. Technical Parameters

Differential Pressure Test: Ranges D, E, N, and Q test a maximum differential pressure of 2000 psi (140 bar) between the inlet and the reduced pressure. Ranges A, B, and H test 3000 psi (210 bar) differential pressure between maximum inlet and depressurization. Ranges C and W are tested to a maximum inlet pressure of 5000 psi (350 bar).
Pressure/Flow Characteristics: Pilot operated valves have very flat pressure/flow characteristics with high stability and low hysteresis....
Dynamic Response: Pilot operated pressure reducing/relieving valves are not fast acting valves. If dynamic response is required, consider using a direct acting valve.
3. Installation and Maintenance

Floating Construction: Sun floating construction is used to minimize the possibility of internal parts seizing due to excessive installation torque and/or variations in cavity/barrel machining1.
Interchangeability: All three-port pressure-reducing and pressure-reducing/relieving valve cartridges are physically interchangeable (i.e., same flow path, same cavity for a given frame size).
