The Sun Hydraulics DPBCOBV (DPBCOBV) is a pilot-operated, three-way directional cartridge designed for moderate flow circuits. This versatile component functions as a switching device that can be used independently or 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 a preset threshold, with pressure at port 3 being directly additive to the valve's setting. It's important to note that port 3 might not be suitable for use as a work port in certain circuits due to this characteristic. The DPBCOBV model is interchangeable with direct-acting versions, sharing the same cavity and flow paths, allowing for easy integration into existing systems. It features Sun's floating style construction to minimize the risk of internal part binding from excessive installation torque or machining variations. This valve is not bistable but can modulate between two positions based on pilot pressure exceeding its setting. If pilot flow becomes an issue when exceeding the valve setting, users may consider switching to a direct-acting version. Key specifications include a T-11A cavity, Series 1 classification, and a capacity of 7 gpm (28 L/min). The maximum operating pressure is rated at 5000 psi (350 bar), with control pilot flow ranging from 7 to 10 in\u00b3/min (0.11 to 0.16 L/min). The valve features an adjustment range of up to 5.5 clockwise turns to increase the setting and requires an installation torque of 30-35 lbf ft (41-47 Nm). The model weighs approximately .60 lb (0.30 kg) and uses Viton seal kits for optimal performance and durability in various hydraulic applications.

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.
