The Sun Hydraulics DPBMKAN (DPBMKAN) is a normally open, pilot-operated, 2-way directional cartridge valve designed for moderate flow circuits. This versatile valve can be used independently or to actuate larger pilot-operated directional cartridges or logic cartridges. It operates by shifting when the pressure differential between port 1 and port 4 exceeds the set threshold. Notably, port 4 can be blocked to prevent the valve from shifting, while port 3 serves as a work port with a maximum pressure limit of 3000 psi due to fatigue strength constraints. The valve is capable of modulating between two positions and is not bistable. Direct-acting and pilot-operated versions are interchangeable, fitting the same cavities with identical flow paths. The valve incorporates Sun's floating style construction, which minimizes internal binding risks from excessive installation torque or machining variations. It features a T21A cavity size, series 1 capacity of 7 gpm (28 L/min), and factory pressure settings established at a flow rate of 4 gpm (15 L/min). The maximum operating pressure stands at an impressive 5000 psi (350 bar), with control pilot flow ranging from 7 to 10 in\u00b3/min (0.11 to 0.16 L/min). The valve's leakage rate is minimal at just 1 in\u00b3/min at 110 SUS (24 cSt) viscosity under a pressure of 1000 psi (70 bar). For adjustments, the setting can be increased through approximately five clockwise turns of the adjustment screw, which has an internal hex size of ^5/32 inches (4 mm). The locknut requires a torque application between 80 and 90 lbf-in (9 to 10 Nm) with a hex size of ^9/16 inches (15 mm). The model weighs approximately .60 lbs (.30 kg) and uses Viton seal kits for optimal performance under varying conditions.

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 4 exceeds the setting.
- Port 4 can be blocked to prevent the valve from shifting.
- Port 3 can be used as a work port.
- Direct-acting and pilot-operated versions of these valves are interchangeable. They fit the same cavities and have the same flow paths.
- Pressure at port 4 is directly additive to the setting of the valve.
- 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.
