The Sun Hydraulics DPBMLAN (DPBMLAN) is a normally open, pilot-operated, 2-way directional cartridge valve designed for moderate flow circuits. This versatile valve can function independently or be used to actuate larger pilot-operated directional cartridges or logic cartridges. It operates by shifting when the pressure differential between port 1 and port 4 surpasses a predetermined setting. Notably, port 4 can be blocked to prevent shifting, while port 3 serves as a work port with a maximum pressure limit of 3000 psi (210 bar) due to fatigue strength constraints. The valve is capable of modulating between two positions and incorporates Sun's floating style construction to minimize internal binding risks caused by excessive torque or machining variations. The DPBMLAN fits T21A cavities and belongs to Series 1 with a capacity of 7 gpm (28 L/min). Factory pressure settings are established at a flow rate of 4 gpm (15 L/min), with the maximum operating pressure reaching up to 5000 psi (350 bar). Control pilot flow ranges from 7 to 10 in\u00b3/min (0.11 to 0.16 L/min), and maximum valve leakage at standard viscosity is limited to 1 in\u00b3/min at 1000 psi (15 cc/min at 70 bar). The adjustment mechanism allows for an increase in setting with approximately five clockwise turns, and the unit requires an installation torque between 30-35 lbf\u00b7ft (41-47 Nm). Additional specifications include a valve hex size of .78 inches (22.2 mm), an adjustment screw internal hex size of .156 inches (4 mm), and a locknut hex size of .5625 inches (15 mm) with torque requirements between 80-90 lbf\u00b7in (9-10 Nm). The model weighs approximately .60 lb (.30 kg) and uses Viton seal kits, specifically part number 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.
