The Sun Hydraulics DPBCKWN (DPBCKWN) is a pilot-operated, 3-way directional cartridge valve designed for moderate flow circuits, offering versatility by acting independently or in conjunction with larger pilot-operated or logic cartridges. This model operates by shifting when the pressure differential between port 1 and port 3 surpasses its set threshold. It's important to note that pressure at port 3 directly adds to the valve's setting, potentially limiting its use as a work port; in such cases, a 4-port version might be more suitable. The valve is not bistable and can modulate between two positions. It fits into cavity T-11A and belongs to series 1, with a capacity of handling up to 7 gpm (28 L/min). The maximum operating pressure stands at 5000 psi (350 bar), with factory pressure settings established at 4 gpm (15 L/min). The valve incorporates Sun\u2019s floating style construction to reduce the risk of internal parts binding due to excessive installation torque or variations in cavity/cartridge machining. When pilot pressure exceeds the valve setting, pilot flow considerations are necessary; if this presents issues, a direct-acting version could be an alternative solution. Installation specifics include a valve hex size of .78 inches (22.2 mm) and an installation torque range of 30-35 lbf ft (41-47 Nm). Additionally, it features an adjustment screw internal hex size of .156 inches (4 mm) and requires locknut torque between 80-90 lbf in (9-10 Nm). The model weighs approximately .60 lb (.30 kg) and utilizes Viton seal kits for optimal performance.

Pilot-operated, 3-way directional cartridges (1 blocked, 2 to 3 open) 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.
