The Sun Hydraulics DPBMCBV (Material Number: DPBMCBV) is a normally open, pilot-operated, 2-way directional cartridge valve designed for moderate flow circuits. It serves as a switching device that can be used independently or 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 the predetermined setting. Port 4 can be blocked to prevent shifting, while port 3 may function as a work port. Both direct-acting and pilot-operated versions of these valves are interchangeable, fitting the same cavities and following identical flow paths. This model features Sun's floating style construction, minimizing the risk of internal parts binding due to excessive installation torque or machining variations in the cavity or cartridge. The DPBMCBV is not bistable but can modulate between two positions as needed. Its maximum operating pressure reaches up to 5000 psi (350 bar) with a capacity of 7 gpm (28 L/min). The valve's design includes a cavity T-21A and it belongs to series 1. For optimal performance, factory pressure settings are established at 4 gpm (15 L/min). The control pilot flow ranges from 7 to 10 in\u00b3/min (0.11 to 0.16 L/min), with maximum valve leakage limited to 1 in\u00b3/min at 1000 psi (15 cc/min at 70 bar). Installation requires a torque of between 30 and 35 lbf-ft (41 and 47 Nm), with an adjustment screw internal hex size of \\(5/32\\) inches (4 mm). A locknut ensures secure adjustments with torque specifications set between 80 and 90 lbf-in (9 and 10 Nm). The model weighs approximately .60 lb (.30 kg) and utilizes a Viton seal kit for enhanced durability.

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.
