The Sun Hydraulics DPBACKV (Material Number: DPBACKV) is a normally open, 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 cartridges or logic cartridges. It functions by shifting when the pressure differential between port 1 and port 3 exceeds the set threshold. Notably, pressure at port 3 directly adds to the valve's setting, which may restrict its use as a work port in certain circuits. If this is a concern, a 4-port version of this valve might be more suitable. The DPBACKV is interchangeable with direct-acting versions as they fit the same cavities and maintain identical flow paths. It is not bistable but can modulate between two positions. The maximum pressure at port 3 should be limited to 3000 psi (210 bar) due to fatigue strength limits rather than hydraulic operating limits. When pilot pressure surpasses the valve setting, consider potential pilot flow issues; if problematic, opting for the direct-acting version could resolve this. This model incorporates Sun's floating style construction to minimize internal part binding due to excessive installation torque or machining variations in cavity/cartridge configurations. It fits into cavity T-11A 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 is limited to 1 in\u00b3/min at 1000 psi (15 cc/min at 70 bar). The adjustment requires up to five clockwise turns for increased settings, with specific torque specifications provided for installation and locknut adjustments.

Normally open, 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.
