The Sun Hydraulics DPCBOBV (DPCBOBV) is a normally closed, pilot-operated, 2-way directional cartridge valve designed for moderate flow circuits. This versatile component can function independently or actuate larger pilot-operated directional or logic cartridges. The valve operates by shifting when the pressure differential between port 1 and port 3 surpasses a predetermined setting, with pressure at port 3 directly adding to this setting. Users should note that maximum pressure at port 3 is limited to 3000 psi (210 bar) due to fatigue strength limits. The DPCBOBV model features a capacity of 15 gpm (60 L/min) and a maximum operating pressure of 5000 psi (350 bar). This valve incorporates Sun's floating style construction to minimize internal part binding caused by excessive installation torque or cavity/cartridge machining variations. It fits the T2A cavity and belongs to series 2, with factory pressure settings established at 4 gpm (15 L/min). The control pilot flow ranges from 10 to 15 in\u00b3/min (0.16 to 0.25 L/min), and the 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 of the valve setting is achieved through up to five turns clockwise, with specific dimensions for the hex size of various components provided for precise installation and adjustment. The model weighs .60 lb (0.30 kg) and comes with a Viton seal kit for optimal performance in hydraulic applications requiring reliable switching under varying pressures.

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.
