The Sun Hydraulics DPBDKWN (DPBDKWN) is a pilot-operated, 3-way directional cartridge valve designed for moderate flow circuits. It facilitates switching between ports, with port 1 to 2 open and port 3 blocked, making it ideal for use on its own or for actuating larger pilot-operated directional or logic cartridges. The valve shifts when the pressure differential between port 1 and port 3 surpasses the set threshold. Notably, pressure at port 3 adds directly to the valve setting, which may limit its use as a work port; in such cases, opting for a four-port version could be beneficial. This model is interchangeable with direct-acting versions, sharing cavity compatibility and flow paths. The DPBDKWN is not bistable but modulates between two positions based on pilot pressure relative to its setting. With a capacity of 7 gpm (28 L/min) and maximum operating pressure of 5000 psi (350 bar), it offers robust performance in hydraulic systems. The valve incorporates Sun's floating style construction to minimize potential binding from excessive installation torque or machining variations. It features an adjustment range that allows up to five clockwise turns to increase settings, with precise installation requirements including a valve hex size of 7/8 inch (22.2 mm) and installation torque of 30-35 lbf ft (41-47 Nm). The DPBDKWN also includes an internal hex size adjustment screw of 5/32 inch (4 mm) and a locknut hex size of 9/16 inch (15 mm), requiring locknut torque between 80-90 lbf in (9-10 Nm). The model weighs .60 lb (.30 kg) and uses Viton seal kits for durability under high-pressure conditions.

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 3 exceeds the setting.
- Pressure at port 3 is directly additive to the setting of the valve. Because of this, port 3 may not be useable as a work port in your circuit. If this is a consideration, the 4 port version of this valve may be a solution.
- Direct-acting and pilot-operated versions of these valves are interchangeable. They fit the same cavities and have the same flow paths.
- Port 3 can be blocked to prevent the valve from shifting.
- This valve is not bistable; it is capable of modulating between the two positions shown.
- 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.
