The Sun Hydraulics DPBMCDN (DPBMCDN) 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 the preset threshold. Port 4 can be blocked to prevent shifting, while port 3 serves as a work port. The valve is interchangeable with direct-acting versions, fitting the same cavities and maintaining identical flow paths. Its design allows for modulation between two positions rather than bistable operation. The maximum pressure at port 3 should not exceed 3000 psi (210 bar) due to fatigue strength limits. The valve incorporates Sun's floating style construction to reduce the risk of internal binding from excessive torque or machining variations. It has a capacity of 7 gpm (28 L/min) and is factory set at a flow rate of 4 gpm (15 L/min). The maximum operating pressure it can handle is up to 5000 psi (350 bar), with control pilot flow ranging from 7 to 10 in\u00b3/min (0.11 to 0.16 L/min). Valve leakage at maximum viscosity is limited to 1 in\u00b3/min per 1000 psi (15 cc/min per 70 bar). For installation, the valve requires a torque of between 30 and 35 lbf\u00b7ft (41 and 47 Nm), with an adjustment screw internal hex size of ^5/32 inch (4 mm). A locknut hex size of ^9/16 inch (15 mm) requires a torque setting of between 80 and 90 lbf\u00b7in (9 and 10 Nm). The model weighs approximately .60 lb (.30 kg), with a Viton seal kit available under part 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.
