The Sun Hydraulics DPBCLKN (DPBCLKN) is a pilot-operated, 3-way directional cartridge valve designed for moderate flow circuits. It can function independently or be used to actuate larger pilot-operated directional cartridges or logic cartridges. The valve operates by shifting when the pressure differential between port 1 and port 3 exceeds its setting. It's important to note that pressure at port 3 directly adds to the valve's setting, which may restrict its use as a work port in certain circuits; in such cases, a 4-port version might be more suitable. This valve is not bistable and can modulate between two positions as needed. If pilot pressure exceeds the valve setting, pilot flow should be considered; if this becomes an issue, switching to a direct-acting version could resolve it. The DPBCLKN incorporates Sun's floating style construction to reduce the risk of internal part binding due to excessive installation torque or cavity/cartridge machining variations. It fits into a T-11A cavity and belongs to Series 1 with a capacity of 7 gpm (28 L/min). The 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), and maximum valve leakage is rated at 1 in\u00b3/min/1000 psi (15 cc/min/70 bar). For adjustments, it requires approximately five clockwise turns to increase the setting, with specific hex sizes provided for various components such as the adjustment screw and locknut. The model weighs approximately .60 lb (0.30 kg) and uses Viton seal kits for optimal performance.

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.
