The Sun Hydraulics DPBBOCN (DPBBOCN) is a normally closed, pilot-operated, 2-way directional cartridge valve designed for moderate flow circuits. This versatile valve can be used independently or to actuate larger pilot-operated directional or logic cartridges. It operates by shifting when the pressure differential between port 1 and port 3 exceeds its preset value, with pressure at port 3 being directly additive to the valve's setting. This characteristic means that port 3 may not be suitable as a work port in some circuits; in such cases, a four-port version could be considered. The DPBBOCN valve is interchangeable with direct-acting versions as they fit the same cavities and share identical flow paths. Notably, this model is not bistable and can modulate between two positions based on pilot pressure exceeding the valve setting. It incorporates Sun's floating style construction to minimize binding due to excessive installation torque or machining variations in cavities or cartridges. This cartridge fits into a T-11A cavity and belongs to series 1 with 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 to 10 in\u00b3/min (0.11 to 0.16 L/min), while maximum valve leakage at 110 SUS (24 cSt) is limited to 1 in\u00b3/min at 1000 psi (15 cc/min at 70 bar). Adjustment involves up to five clockwise turns, and installation requires a torque of between 30 and 35 lbf ft (41 and 47 Nm). The valve features an internal hex size of ^5\u204432 inches for adjustment screws and comes with a Viton seal kit for maintenance purposes.

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.
- 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.
