The Sun Hydraulics DPBBLKN (DPBBLKN) is a normally closed, pilot-operated, 2-way directional cartridge valve designed for moderate flow circuits. It can function independently or be used to control larger pilot-operated directional or logic cartridges. The valve operates by shifting when the pressure differential between port 1 and port 3 surpasses a specific setting, with pressure at port 3 directly adding to this setting. Consequently, port 3 may not be suitable as a work port in certain circuits; in such cases, the four-port version of this valve might be more appropriate. The DPBBLKN is capable of modulating between two positions and is not bistable. When pilot pressure exceeds the valve setting, pilot flow becomes an important consideration; performance curves should be reviewed for pilot consumption relative to load pressure above the valve setting. If excessive pilot flow is an issue, opting for the direct-acting version could resolve it. The valve features Sun's floating style construction to reduce internal binding risks due to excessive installation torque or cavity/cartridge machining variations. This model fits into T-11A cavities 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), with a maximum operating pressure of 5000 psi (350 bar). Control pilot flow ranges from 7 to 10 in\u00b3/min (0.11 - 0.16 L/min), and maximum valve leakage at 110 SUS (24 cSt) is limited to 1 in\u00b3/min (15 cc/min) at 1000 psi (70 bar). The adjustment requires up to five clockwise turns to increase the setting, with specific torque specifications for installation and locknut adjustments provided for optimal performance and reliability.

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.
