The Sun Hydraulics DPBPLWV (DPBPLWV) is a pilot-operated, 3-way directional cartridge valve designed for moderate flow circuits, providing versatility in hydraulic systems. This valve features an open path from port 1 to port 2 while blocking port 3, making it suitable for various applications where controlled fluid direction is required. It can function independently or in conjunction with larger pilot-operated or logic cartridges, offering flexibility in circuit design. The valve operates by shifting when the pressure differential between port 1 and port 4 surpasses a preset threshold, with the option to block port 4 to prevent shifting. Additionally, port 3 can be utilized as a work port. The DPBPLWV model is interchangeable with direct-acting valves due to its consistent cavity fit and flow paths. It incorporates Sun's floating style construction to reduce internal binding risks caused by excessive torque or machining variations. The valve's maximum operating pressure is rated at 5000 psi (350 bar), with a capacity of handling flows up to 7 gpm (28 L/min). Factory pressure settings are established at a flow rate of 4 gpm (15 L/min). Notably, this valve is not bistable but rather capable of modulating between two positions, which enhances its application scope in dynamic systems. Users should consider pilot flow consumption if pilot pressure exceeds the valve setting; opting for a direct-acting version may resolve potential issues. The DPBPLWV also features adjustable settings facilitated by an internal hex screw and locknut configuration, ensuring precise control over system parameters. With its robust design and adaptability, this cartridge valve serves as an integral component in maintaining efficient hydraulic operations.

Pilot-operated, 3-way directional cartridges (1 to 2 open, 3 blocked) are switching devices typically used in moderate flow circuits. They can be used by themselves or to actuate larger pilot operated directional cartridges or logic cartridges. The valve shifts when the pressure differential between port 1 and port 4 exceeds the setting.
- Port 4 can be blocked to prevent the valve from shifting.
- Port 3 can be used as a work port.
- Direct-acting and pilot-operated versions of these valves are interchangeable. They fit the same cavities and have the same flow paths.
- Pressure at port 4 is directly additive to the setting of the valve.
- This valve is not bistable; it is capable of modulating between the two positions shown.
- Maximum pressure at port 3 should be limited to 3000 psi (210 bar). This is due to fatigue strength limits not hydraulic operating limits.
- When pilot pressure exceeds the valve setting, pilot flow may be a consideration. See performance curves for pilot consumption vs. load pressure above the valve setting. If this is a problem, the direct acting version of this valve would be a solution.
- Incorporates the Sun floating style construction to minimize the possibility of internal parts binding due to excessive installation torque and/or cavity/cartridge machining variations.
