The Sun Hydraulics DPCBKBN (DPCBKBN) is a normally closed, pilot-operated, 2-way directional cartridge valve designed for moderate flow circuits. It functions as a switching device and can be used independently or to actuate larger pilot-operated directional or logic cartridges. This valve shifts when the pressure differential between port 1 and port 3 exceeds the set value, with pressure at port 3 directly adding to the setting of the valve. Consequently, port 3 may not be suitable as a work port unless using the 4-port version of this valve. The DPCBKBN is not bistable; it modulates between two positions and has interchangeable direct-acting and pilot-operated versions fitting the same cavities with identical flow paths. The valve features Sun's floating style construction, minimizing internal part binding due to excessive torque or machining variations. It operates with a maximum pressure at port 3 limited to 3000 psi (210 bar) due to fatigue strength limits. The cavity type is T-2A, with a series designation of 2, and it supports a capacity of up to 15 gpm (60 L/min). Factory pressure settings are established at 4 gpm (15 L/min), while the maximum operating pressure reaches up to 5000 psi (350 bar). Control pilot flow ranges between 10-15 in\u00b3/min (0.16-0.25 L/min), with maximum leakage at specified conditions being minimal at approximately 1 in\u00b3/min per 1000 psi (15 cc/min per 70 bar). Adjustment requires up to five clockwise turns to increase settings, and installation specifics include a valve hex size of 1-1/8 inch (28.6 mm) and torque requirements of 45-50 lbf ft (61-68 Nm). The adjustment screw has an internal hex size of 5/32 inch (4 mm), while locknut specifications include a hex size of 9/16 inch (15 mm) and torque range of 80-90 lbf in (9-10 Nm). The model weighs approximately .60 lb (.30 kg) and utilizes Viton seal kits for optimal performance.

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 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.
- 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.
