The Sun Hydraulics DPBMKBV (DPBMKBV) 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 shifts based on the pressure differential between port 1 and port 4, with the option to block port 4 to prevent shifting. Port 3 can serve as a work port, and the valve's design allows for interchangeability between direct-acting and pilot-operated versions, fitting the same cavities with identical flow paths. The DPBMKBV model incorporates Sun's floating style construction to minimize internal binding risks due to excessive installation torque or machining variations. It is capable of modulating between two positions but is not bistable. The valve operates with a maximum pressure at port 3 limited to 3000 psi (210 bar) due to fatigue strength limits rather than hydraulic operating limits. The cavity size is T-21A with a series designation of 1 and a capacity of 7 gpm (28 L/min). Factory pressure settings are established at 4 gpm (15 L/min), while the maximum operating pressure reaches up to 5000 psi (350 bar). Additional specifications include control pilot flow rates of 7-10 in\u00b3/min (0.11-0.16 L/min), maximum valve leakage at specified conditions being 1 in\u00b3/min (15 cc/min), and an adjustment range that requires approximately five turns clockwise to increase settings. The valve's hex size measures 7/8 inch (22.2 mm), with an installation torque requirement of 30-35 lbf ft (41-47 Nm). For adjustments, it features an internal hex screw size of 5/32 inch (4 mm) and a locknut hex size of 9/16 inch (15 mm), necessitating a locknut torque of 80-90 lbf in (9-10 Nm). The model weighs approximately .60 lb (.30 kg) and uses Viton seal kits 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.
