The Sun Hydraulics DPCMLBN (Material Number: DPCMLBN) is a normally open, pilot-operated, 2-way directional cartridge valve designed for moderate flow circuits. This versatile component can function independently or be used to actuate larger pilot-operated directional or logic cartridges. The valve operates by shifting when the pressure differential between port 1 and port 4 surpasses its preset threshold. 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 considerations. The DPCMLBN incorporates Sun's floating style construction to minimize internal binding risks from excessive installation torque or machining variations. With a cavity size of T22A and belonging to Series 2, this cartridge has a capacity of managing up to 15 gpm (60 L/min). Factory pressure settings are established at a flow rate of 4 gpm (15 L/min), and it can withstand a maximum operating pressure of up to 5000 psi (350 bar). The control pilot flow ranges between 10 - 15 in\u00b3/min (0.16 - 0.25 L/min), with maximum valve leakage at specified conditions limited to 1 in\u00b3/min (1000 psi or about 15 cc/min at 70 bar). The adjustment mechanism allows for increasing the setting through approximately five clockwise turns, with specific dimensions provided for installation and adjustment tools: valve hex size is 1-1/8 inches (28.6 mm), installation torque is between 45 - 50 lbf\u00b7ft (61 - 68 Nm), adjustment screw internal hex size is 5/32 inches (4 mm), locknut hex size is 9/16 inches (15 mm), and locknut torque ranges from 80 -90 lbf\u00b7in (9 -10 Nm). The model weighs around .60 lb (.30 kg) and includes a Viton seal kit for optimal 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.
