The Sun Hydraulics DPBAOCN (DPBAOCN) is a normally open, pilot-operated, 2-way directional cartridge designed for moderate flow circuits. It can be utilized independently or to actuate larger pilot-operated directional cartridges or logic cartridges. The valve operates by shifting when the pressure differential between port 1 and port 3 exceeds its set threshold. The pressure at port 3 directly adds to the valve's setting, which means it might not be suitable as a work port in certain circuit configurations. If this poses an issue, a 4-port version of the valve is recommended. This model is interchangeable with direct-acting versions, fitting the same cavities and maintaining identical flow paths. It is capable of modulating between two positions but is not bistable. The maximum allowable pressure at port 3 is limited to 3000 psi (210 bar), dictated by fatigue strength rather than hydraulic limits. Pilot flow should be considered if pilot pressure exceeds the valve setting; performance curves provide insights into pilot consumption versus load pressure above the set point. For scenarios where this becomes problematic, opting for a direct-acting version may resolve issues. This cartridge uses Sun's floating style construction to minimize internal part binding due to excessive installation torque or cavity/cartridge machining variations. It features a T11A cavity, Series 1 classification, with a capacity of 7 gpm (28 L/min) and factory pressure settings established at 4 gpm (15 L/min). The maximum operating pressure is rated at 5000 psi (350 bar). Control pilot flow ranges from 7 to 10 in\u00b3/min (0.11 to 0.16 L/min), and maximum valve leakage at standard conditions is limited to 1 in\u00b3/min/1000 psi (15 cc/min/70 bar). Adjustments can be made with up to five clockwise turns, and proper installation requires specific torque settings for both the valve and locknut components.

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.
