The Sun Hydraulics DPBMKDV (DPBMKDV) is a normally open, pilot-operated, 2-way directional cartridge valve designed for use in 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 the set threshold, though port 4 can be blocked to prevent this shift. Port 3 serves as a work port with a maximum pressure limit of 3000 psi (210 bar) due to fatigue strength constraints. This valve is not bistable and can modulate between two positions, allowing for precise control within hydraulic systems. The DPBMKDV features Sun's floating style construction, which minimizes the risk of internal binding from excessive installation torque or cavity machining variations. It fits into cavity T-21A and belongs to series 1, offering a capacity of 7 gpm (28 L/min). Factory pressure settings are established at a flow rate of 4 gpm (15 L/min), with a maximum operating pressure of up to 5000 psi (350 bar). The control pilot flow ranges from 7 to 10 in\u00b3/min (0.11 to 0.16 L/min), while maximum valve leakage at 110 SUS (24 cSt) is limited to 1 in\u00b3/min at 1000 psi (15 cc/min at 70 bar). Adjustments can be made by turning clockwise up to five times, with specific hex sizes detailed for various components: valve hex size is .78 inches (22.2 mm), adjustment screw internal hex size is .532 inches (4 mm), and locknut hex size is .916 inches (15 mm). Installation torque ranges from 30 to 35 lbf\u00b7ft (41 to 47 Nm), while locknut torque should be maintained between 80 and 90 lbf\u00b7in (9 to 10 Nm). The model weighs approximately .60 lb (.30 kg) and utilizes Viton seal kits for enhanced durability and performance.

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.
