The Sun Hydraulics DPBNLAV (DPBNLAV) is a normally closed, pilot-operated, 2-way directional cartridge valve designed for moderate flow circuits. It can function independently or in conjunction with larger pilot-operated directional or logic cartridges. The valve operates by shifting when the pressure differential between port 1 and port 4 surpasses the designated setting, with the option to block port 4 to prevent shifting and utilize port 3 as a work port. This valve is capable of modulating between two positions rather than being bistable and features interchangeable direct-acting and pilot-operated versions that fit the same cavities with identical flow paths. The DPBNLAV is constructed using Sun's floating style to reduce internal binding risks due to excessive installation torque or machining variations. It is designed with a T21A cavity, series 1, and has a capacity of 7 gpm (28 L/min). Factory pressure settings are established at 4 gpm (15 L/min), with a maximum operating pressure of 5000 psi (350 bar). Control pilot flow ranges from 7-10 in\u00b3/min (0.11-0.16 L/min), while maximum valve leakage at 110 SUS (24 cSt) is limited to 1 in\u00b3/min per 1000 psi (15 cc/min per 70 bar). The DPBNLAV includes precise adjustment features, such as a screw internal hex size of 5/32 in. (4 mm) and locknut hex size of 9/16 in. (15 mm), with adjustment requiring up to five clockwise turns to increase settings. The installation torque for the valve is specified at 30-35 lbf ft (41-47 Nm), and locknut torque ranges from 80-90 lbf in. (9-10 Nm). Weighing .60 lb (.30 kg), this model also comes with a Viton seal kit for optimal performance and durability in various applications.

Normally closed, 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.
