The Sun Hydraulics DPBDKAV (DPBDKAV) is a pilot-operated, 3-way directional cartridge valve designed for moderate flow circuits. This versatile valve can function independently or be used to actuate larger pilot-operated directional or logic cartridges. It operates by shifting when the pressure differential between port 1 and port 3 surpasses the set threshold, with pressure at port 3 directly adding to the valve setting. Notably, if port 3 usage as a work port is a concern, a 4-port version of this valve might be more suitable. The DPBDKAV features interchangeable direct-acting and pilot-operated versions that fit the same cavities and share identical flow paths. Additionally, blocking port 3 prevents the valve from shifting. This non-bistable valve modulates between two positions based on pilot pressure exceeding its setting; thus, pilot flow considerations are essential. If pilot consumption versus load pressure becomes an issue, opting for the direct-acting version could resolve it. The design incorporates Sun's floating style construction to minimize internal part binding due to excessive installation torque or machining variations in cavity/cartridge setups. Key specifications include compatibility with cavity T-11A and a series 1 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 to 10 in\u00b3/min (0.11 to 0.16 L/min), while leakage is limited to a maximum of 1 in\u00b3/min at 1000 psi (15 cc/min at 70 bar). The adjustment mechanism involves up to five clockwise turns for increased settings, with specific torque requirements for installation and locknut adjustments ensuring secure operation.

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 3 exceeds the setting.
- Pressure at port 3 is directly additive to the setting of the valve. Because of this, port 3 may not be useable as a work port in your circuit. If this is a consideration, the 4 port version of this valve may be a solution.
- Direct-acting and pilot-operated versions of these valves are interchangeable. They fit the same cavities and have the same flow paths.
- Port 3 can be blocked to prevent the valve from shifting.
- This valve is not bistable; it is capable of modulating between the two positions shown.
- 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.
