The Sun Hydraulics DPBPCEN (DPBPCEN) is a pilot-operated, 3-way directional cartridge valve designed for moderate flow circuits. This versatile valve can function independently or be used to actuate larger pilot-operated directional or logic cartridges. The valve operates by shifting when the pressure differential between port 1 and port 4 exceeds a predefined setting, with port 4 capable of being blocked to prevent this shift. Port 3 serves as a work port, and the valve's design allows interchangeability with direct-acting versions, fitting the same cavities and maintaining identical flow paths. It features a maximum operating pressure of 5000 psi (350 bar) and a capacity of 7 gpm (28 L/min). Its unique construction minimizes internal binding risks due to installation torque or machining variations. The valve is not bistable but can modulate between two positions, with pressure at port 4 directly affecting its setting. The maximum pressure at port 3 should not exceed 3000 psi (210 bar) due to fatigue strength limitations. In scenarios where pilot pressure surpasses the valve setting, pilot flow considerations are important; in such cases, opting for the direct-acting version could be beneficial. The DPBPCEN incorporates Sun's floating style construction for enhanced reliability during installation. Additional specifications include a cavity size of T-21A, series number 1, factory pressure settings established at 4 gpm (15 L/min), control pilot flow range of 7\u201310 in\u00b3/min (0.11\u20130.16 L/min), and maximum valve leakage at specified conditions of 1 in\u00b3/min (15 cc/min). The adjustment screw features an internal hex size of 5/32 inch (4 mm), while the locknut hex size is set at 9/16 inch (15 mm), with corresponding torque requirements detailed for optimal performance.

Pilot-operated, 3-way directional cartridges (1 to 2 open, 3 blocked) 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 4 exceeds the setting.
- Port 4 can be blocked to prevent the valve from shifting.
- Port 3 can be used as a work port.
- Direct-acting and pilot-operated versions of these valves are interchangeable. They fit the same cavities and have the same flow paths.
- Pressure at port 4 is directly additive to the setting of the valve.
- 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.
