The Sun Hydraulics DPBMKJV (DPBMKJV) 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 a predetermined setting. Unique features include the ability to block port 4 to prevent shifting and utilize port 3 as a work port. Notably, direct-acting and pilot-operated versions of these valves are interchangeable, fitting the same cavities with identical flow paths. This valve is characterized by its capacity to modulate between two positions rather than being bistable. It supports a maximum pressure of 3000 psi at port 3 due to fatigue strength limits. Pilot flow considerations arise when pilot pressure exceeds the valve setting; in such cases, opting for the direct-acting version might be beneficial. The valve incorporates Sun's floating style construction, minimizing internal part binding risks from excessive installation torque or cavity/cartridge machining variations. With a cavity specification of T-21A and belonging to Series 1, this model has a capacity of 7 gpm (28 L/min) with factory pressure settings established at 4 gpm (15 L/min). The maximum operating pressure is rated at 5000 psi (350 bar), and control pilot flow ranges from 7 to 10 in\u00b3/min (0.11 to 0.16 L/min). It features an adjustment mechanism that requires up to five clockwise turns to increase settings, with specific torque requirements for installation and adjustments. The model weighs approximately .60 lb (0.30 kg) and uses Viton seal kits for optimal performance in hydraulic systems.

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.
