The Sun Hydraulics DPBMKEN (DPBMKEN) is a normally open, pilot-operated, 2-way directional cartridge valve designed for moderate flow circuits. This versatile component can function independently or in conjunction with larger pilot-operated directional or logic cartridges. The valve operates by shifting when the pressure differential between port 1 and port 4 surpasses a predefined setting, with port 4 being blockable to prevent unwanted shifts. Port 3 serves as a work port and should not exceed a maximum pressure of 3000 psi (210 bar) due to fatigue strength limits. The valve is capable of modulating between two positions but is not bistable. It features interchangeable direct-acting and pilot-operated versions that fit the same cavities and flow paths. Incorporating Sun's floating style construction, this valve minimizes the risk of internal parts binding from excessive installation torque or machining variations. It has a cavity size of T21A, belongs to series 1, and offers a capacity of 7 gpm (28 L/min), with factory pressure settings established at 4 gpm (15 L/min). The maximum operating pressure is rated at 5000 psi (350 bar), while control pilot flow ranges between 7 and 10 in\u00b3/min (0.11 to 0.16 L/min). Maximum leakage at 110 SUS (24 cSt) measures at just 1 in\u00b3/min per 1000 psi (15 cc/min per 70 bar). For installation, the valve requires a hex size of .78 inches (22.2 mm) and an installation torque between 30 to 35 lbf ft (41 to 47 Nm). The adjustment screw has an internal hex size of .532 inches (4 mm), with a locknut hex size of .916 inches (15 mm) and torque specifications of 80 to 90 lbf in (9 to 10 Nm). Weighing approximately .60 lb (.30 kg), this model uses Viton seals, specifically seal kit number: Viton:990021006.

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.
