The Sun Hydraulics DPBCKDN (DPBCKDN) is a pilot-operated, 3-way directional cartridge valve designed for moderate flow circuits. It functions by blocking one port while allowing flow between the other two ports, making it suitable for applications where directional control of fluid is required. The valve activates when the pressure differential between port 1 and port 3 surpasses a predetermined setting. Notably, pressure at port 3 directly affects the valve's setting, potentially limiting its use as a work port unless a 4-port version is employed. This model features interchangeable direct-acting and pilot-operated versions that share identical cavities and flow paths. The DPBCKDN can modulate between two positions without being bistable, with pilot pressure influencing pilot flow based on performance curves. If excessive pilot flow becomes an issue, opting for a direct acting version may be beneficial. The valve incorporates Sun's floating style construction to reduce internal binding risks due to installation torque or machining variations. Key specifications include a T-11A cavity, series 1 classification, and a capacity of 7 gpm (28 L/min). It operates at a maximum pressure of 5000 psi (350 bar) with factory settings established at 4 gpm (15 L/min). Control pilot flow ranges from 7 to 10 in\u00b3/min (0.11 to 0.16 L/min), with minimal leakage under specified conditions. The adjustment mechanism allows up to five clockwise turns to increase settings, with specific torque requirements for installation and locknut adjustments. The DPBCKDN weighs approximately .60 lb (0.30 kg) and uses Viton seal kits for maintenance. With its robust design and adjustable settings, this cartridge valve provides reliable directional control in hydraulic systems where precise modulation is essential.

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