The Sun Hydraulics DPBDKBN (DPBDKBN) is a pilot-operated, 3-way directional cartridge valve designed for moderate flow circuits. This versatile valve can be used independently or to actuate larger pilot-operated directional or logic cartridges. It functions by shifting when the pressure differential between port 1 and port 3 surpasses the set threshold. Notably, pressure at port 3 directly adds to the valve setting, which may restrict its use as a work port in certain circuits; a 4-port version may be preferable in such cases. The DPBDKBN is not bistable and can modulate between two positions, with pilot flow potentially becoming a factor when pilot pressure exceeds the valve setting. The valve features Sun's floating style construction to reduce internal binding risks due to installation torque or machining variations. It fits into the T-11A cavity and belongs to Series 1, with a capacity of 7 gpm (28 L/min) and a maximum operating pressure of 5000 psi (350 bar). The factory pressure settings are established at 4 gpm (15 L/min), with control pilot flow ranging from 7 to 10 in\u00b3/min (0.11 to 0.16 L/min). Maximum valve leakage is specified at 1 in\u00b3/min (1000 psi) or approximately 15 cc/min (70 bar). Adjustments can be made with up to five clockwise turns, using an internal hex size of 5/32 inches (4 mm), while installation torque ranges from 30 to 35 lbf-ft (41 to 47 Nm). The DPBDKBN weighs approximately .60 lb (.30 kg) and comes with a Viton seal kit under part number: 990011006.

Pilot-operated, 3-way directional cartridges (1 to 2 open, 3 blocked) 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.
- Port 3 can be blocked to prevent the valve from shifting.
- 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.
