The Sun Hydraulics DPBAKBV (DPBAKBV) is a normally open, pilot-operated, 2-way directional cartridge valve designed for moderate flow circuits. It can function independently or in conjunction with larger pilot-operated directional or logic cartridges. The valve operates by shifting when the pressure differential between port 1 and port 3 surpasses its set threshold, with pressure at port 3 being directly additive to the valve setting. This feature implies that port 3 may not be suitable as a work port; for such applications, a 4-port version might be necessary. This valve is capable of modulating between two positions but is not bistable. The DPBAKBV fits into cavity T-11A and belongs to series 1 with a capacity of 7 gpm (28 L/min). It has a maximum operating pressure of 5000 psi (350 bar) and incorporates Sun's floating style construction to reduce the risk of internal binding due to installation torque or machining variations. The factory pressure settings are established at a flow rate of 4 gpm (15 L/min), and the control pilot flow ranges from 7 to 10 in\u00b3/min (0.11 to 0.16 L/min). Maximum leakage at standard conditions is limited to 1 in\u00b3/min (1000 psi or approximately 15 cc/min at 70 bar). The DPBAKBV features an adjustment screw with an internal hex size of 5/32 inch (4 mm) and requires up to five clockwise turns for setting adjustments. It also includes a locknut with a hex size of 9/16 inch (15 mm), which should be torqued between 80-90 lbf-in (9-10 Nm). Weighing approximately .60 lb (.30 kg), this cartridge valve offers robust performance for various hydraulic applications where precise modulation and reliable switching are essential.

Normally open, pilot-operated, 2-way directional cartridges 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.
- 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.
