The Sun Hydraulics DPBAOKN (DPBAOKN) is a normally open, pilot-operated, 2-way directional cartridge valve designed for moderate flow circuits. It functions as a switching device and can be used independently or to actuate larger pilot-operated directional cartridges or logic cartridges. This valve shifts when the pressure differential between port 1 and port 3 exceeds its set threshold, with pressure at port 3 being directly additive to the valve's setting. However, port 3 may not be suitable as a work port due to this characteristic; in such cases, a 4-port version of the valve might be more appropriate. The DPBAOKN is not bistable but can modulate between two positions. Its maximum pressure at port 3 is limited to 3000 psi (210 bar) due to fatigue strength considerations rather than hydraulic limits. The valve incorporates Sun's floating style construction to minimize internal parts binding from excessive installation torque or cavity/cartridge machining variations. This cartridge valve fits the T-11A cavity, belongs to series 1, and has a capacity of 7 gpm (28 L/min). It operates at a maximum pressure of 5000 psi (350 bar) with factory pressure settings established at 4 gpm (15 L/min). Control pilot flow ranges from 7-10 in\u00b3/min (0.11-0.16 L/min), with maximum leakage capped at 1 in\u00b3/min/1000 psi (15 cc/min/70 bar). The adjustment requires up to five clockwise turns to increase settings, with specific torque values for installation and locknut adjustments. The DPBAOKN weighs approximately .60 lb (.30 kg) and comes with a Viton seal kit option for enhanced durability under various operational conditions.

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.
