The Sun Hydraulics DPBAKBN (Material Number: DPBAKBN) is a normally open, pilot-operated, 2-way directional cartridge valve designed for moderate flow circuits. This versatile component can function independently or be used to actuate larger pilot-operated directional or logic cartridges. It operates by shifting when the pressure differential between port 1 and port 3 surpasses the valve's set threshold, with the pressure at port 3 being directly additive to this setting. Notably, this valve is not bistable and can modulate between two positions as needed. It features a maximum operating pressure of 5000 psi (350 bar) and has a capacity of 7 gpm (28 L/min). The maximum pressure at port 3 should be limited to 3000 psi (210 bar) due to fatigue strength limits, although this does not affect hydraulic operation limits. The DPBAKBN incorporates Sun's floating style construction, minimizing the risk of internal parts binding from excessive installation torque or cavity/cartridge machining variations. It fits into a T-11A cavity and belongs to Series 1. The factory pressure settings are established at a flow rate of 4 gpm (15 L/min), ensuring reliable performance in various applications. The valve allows for control pilot flow ranging from 7 to 10 in\u00b3/min (0.11 to 0.16 L/min), with maximum leakage at standard conditions being just 1 in\u00b3/min per 1000 psi (15 cc/min per 70 bar). For adjustments, it requires approximately five clockwise turns to increase the setting, facilitated by an internal hex size of 5/32 inches (4 mm). The valve is compact with a model weight of .60 lb (0.30 kg), making it suitable for integration into diverse hydraulic systems where space and weight are considerations.

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.
