The Sun Hydraulics DPBACDN (DPBACDN) 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 exceeds a predetermined setting, with pressure at port 3 being additive to this setting. This configuration may limit the use of port 3 as a work port, suggesting that a 4-port version could be more suitable in such scenarios. The DPBACDN is not bistable and can modulate between two positions. The valve incorporates Sun's floating style construction to reduce the risk of internal binding due to excessive installation torque or machining variations. It fits into a T-11A cavity and belongs to series 1, with a capacity of 7 gpm (28 L/min). Factory pressure settings are established at 4 gpm (15 L/min), and it can handle a maximum operating pressure of up to 5000 psi (350 bar). Control pilot flow ranges from 7 to 10 in\u00b3/min (0.11 to 0.16 L/min), while maximum valve leakage at standard conditions is limited to 1 in\u00b3/min at 1000 psi (15 cc/min at 70 bar). The adjustment mechanism allows for increased settings through approximately five turns clockwise, with specific torque requirements for installation and locknut adjustments provided for precision fitting. The DPBACDN model weighs approximately .60 lb (0.30 kg) and includes Viton seal kits for maintenance purposes. This versatile valve offers reliable performance across various applications requiring moderate flow control with precise modulation capabilities.

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.
