The Sun Hydraulics DPBBOBN (DPBBOBN) is a normally closed, pilot-operated, 2-way directional cartridge valve designed for use in moderate flow circuits. This versatile component can function independently or be utilized 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 surpasses the preset threshold. Notably, pressure at port 3 directly adds to the valve's setting, which may affect its usability as a work port in certain circuits. In such cases, opting for the 4-port version could be beneficial. Direct-acting and pilot-operated versions of these valves are interchangeable; they share identical cavities and flow paths. This valve is not bistable but can modulate between two positions based on pilot pressure exceeding its setting\u2014pilot flow considerations are essential in such scenarios. If pilot consumption becomes problematic, switching to the direct-acting version might be a viable solution. The DPBBOBN incorporates Sun's floating style construction to minimize potential binding of internal parts due to excessive installation torque or variations in cavity/cartridge machining. Key specifications include compatibility with T-11A cavities, a series 1 designation, and a capacity of up to 7 gpm (28 L/min). Factory pressure settings are established at 4 gpm (15 L/min), with a maximum operating pressure of 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 110 SUS (24 cSt) is limited to 1 in\u00b3/min/1000 psi (15 cc/min/70 bar). The valve features an adjustment mechanism with up to five clockwise turns for setting increases, an installation torque requirement of 30\u201335 lbf ft (41\u201347 Nm), and includes Viton seal kits for enhanced durability and performance.

Normally closed, 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.
- 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.
