The Sun Hydraulics DPBDKKN (DPBDKKN) is a pilot-operated, 3-way directional cartridge valve designed for moderate flow circuits. It features an open path from port 1 to port 2 while blocking port 3, making it suitable for use on its own or to actuate 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 directly additive to the valve's setting. This model is not bistable and can modulate between two positions based on pilot pressure exceeding the set threshold. It incorporates Sun's floating style construction, which reduces the risk of internal binding due to excessive installation torque or cavity machining variations. The DPBDKKN fits into a T-11A cavity and belongs to series 1, with a capacity of handling up to 7 gallons per minute (28 liters per minute). It can operate at a maximum pressure of 5000 psi (350 bar), with factory pressure settings established at a flow rate of 4 gpm (15 L/min). The control pilot flow ranges from 7 to 10 in\u00b3/min (0.11 to 0.16 L/min), and it has a maximum leakage rate of 1 in\u00b3/min at an oil viscosity of 110 SUS (24 cSt) under a pressure of 1000 psi (70 bar). The valve allows for adjustment via clockwise turns, with specific dimensions provided for installation torque and hex sizes for adjustment screws and locknuts. The model weighs approximately .60 lb (.30 kg) and uses Viton seal kits for effective sealing performance.

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.
