The Sun Hydraulics DPBMCWN (DPBMCWN) is a normally open, pilot-operated, 2-way directional cartridge valve designed for moderate flow circuits. This versatile component can function independently or actuate larger pilot-operated directional or logic cartridges. The valve operates by shifting when the pressure differential between port 1 and port 4 exceeds its set threshold, and port 4 can be blocked to prevent shifting. Port 3 serves as a work port with a maximum pressure limit of 3000 psi (210 bar) due to fatigue strength considerations. The valve is not bistable and can modulate between two positions, offering smooth transitions in operation. Incorporating Sun's floating style construction, the DPBMCWN minimizes internal binding risks due to excessive installation torque or machining variations. It fits the T-21A cavity 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 a maximum operating pressure of 5000 psi (350 bar). Control pilot flow ranges from 7 to 10 in\u00b3/min (0.11 to 0.16 L/min), while maximum valve leakage at standard viscosity conditions is limited to 1 in\u00b3/min at 1000 psi (15 cc/min at 70 bar). The adjustment mechanism allows for setting increases through up to five full clockwise turns, with specific torque requirements for both installation and locknut adjustments. The valve's hex size measures .78 inches (22.2 mm), with an installation torque range of 30-35 lbf ft (41-47 Nm). The adjustment screw features an internal hex size of .532 inches (4 mm), while the locknut hex size is .916 inches (15 mm) requiring a torque of 80-90 lbf in (9-10 Nm). Weighing just .60 lb (.30 kg), this model offers robust performance in hydraulic applications requiring precise control and modulation capabilities.

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.
