The Sun Hydraulics DPBPKEV (DPBPKEV) is a pilot-operated, 3-way directional cartridge valve designed for moderate flow circuits. It functions by opening the flow path between ports 1 and 2 while blocking port 3, which can also be utilized as a work port. This valve is interchangeable with direct-acting versions, sharing the same cavity (T-21A) and flow paths. The valve shifts when the pressure differential between port 1 and port 4 exceeds the set threshold, although blocking port 4 can prevent this shift. The maximum operating pressure is rated at 5000 psi (350 bar), with a capacity of handling flows up to 7 gpm (28 L/min). Factory pressure settings are established at a flow of 4 gpm (15 L/min). Notably, this valve is not bistable and can modulate between two positions. The DPBPKEV incorporates Sun's floating style construction to minimize internal binding risks due to installation torque or machining variations. When pilot pressure surpasses the valve setting, pilot flow becomes a consideration, which can be addressed by opting for the direct-acting version if necessary. The maximum allowable pressure at port 3 is limited to 3000 psi (210 bar) due to fatigue strength limits rather than hydraulic operating limits. For adjustment purposes, the valve features an internal hex screw and locknut with specific torque requirements: adjustment screw size of 5/32 in. (4 mm) and locknut hex size of 9/16 in. (15 mm). Weighing approximately .60 lb (.30 kg), it requires installation torque between 30 - 35 lbf ft (41 - 47 Nm). A Viton seal kit is available for this model under part number: 990021006.

Pilot-operated, 3-way directional cartridges (1 to 2 open, 3 blocked) 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.
