The Sun Hydraulics DPBAKCN (DPBAKCN) is a normally open, pilot-operated, 2-way directional cartridge valve designed for moderate flow circuits. This versatile component can function independently or be utilized to actuate larger pilot-operated directional or logic cartridges. The valve shifts its position when the pressure differential between port 1 and port 3 surpasses the preset value, with pressure at port 3 being directly additive to the valve setting. However, port 3 may not be suitable as a work port due to this characteristic; opting for a 4-port version could resolve this issue if necessary. Engineered with interchangeable direct-acting and pilot-operated versions, this valve fits the same cavities and maintains consistent flow paths across configurations. It is capable of modulating between two positions but is not bistable. The maximum allowable pressure at port 3 is capped at 3000 psi (210 bar) due to fatigue strength limits rather than hydraulic operating constraints. If pilot flow becomes a concern when pilot pressure exceeds the valve setting, considering the direct-acting variant might be advisable. The DPBAKCN features Sun's floating style construction, minimizing risks of internal part binding due to excessive torque or machining variations. It fits into cavity T-11A and belongs to Series 1 with a capacity of 7 gpm (28 L/min). Factory pressure settings are established at a flow rate of 4 gpm (15 L/min), with a maximum operating pressure of up to 5000 psi (350 bar). The control pilot flow ranges from 7-10 in\u00b3/min (0.11-0.16 L/min), while maximum valve leakage is limited to 1 in\u00b3/min at 1000 psi (15 cc/min at 70 bar). Installation requires specific torque settings for optimal performance and reliability.

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.
