The Sun Hydraulics DPBACAV (DPBACAV) is a normally open, pilot-operated, 2-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. It operates by shifting when the pressure differential between port 1 and port 3 exceeds its set threshold. Importantly, pressure at port 3 is additive to the valve setting, which may limit its use as a work port in some circuits; in such cases, a 4-port version might be more suitable. The DPBACAV can modulate between two positions but is not bistable. The maximum pressure at port 3 should not exceed 3000 psi (210 bar) due to fatigue strength limits. This valve features Sun's floating style construction to reduce the risk of internal part binding during installation or due to machining variations. The DPBACAV 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 a flow rate of 4 gpm (15 L/min), while it supports a maximum operating pressure of up to 5000 psi (350 bar). The control pilot flow ranges from 7 to 10 in\u00b3/min (0.11 - 0.16 L/min), with maximum valve leakage limited to 1 in\u00b3/min at 1000 psi (15 cc/min at 70 bar). Adjustment for increasing the setting requires approximately five full clockwise turns. Installation requires specific torque values: valve installation torque is between 30 - 35 lbf\u00b7ft (41 - 47 Nm), and locknut torque ranges from 80 -90 lbf\u00b7in (9 -10 Nm). The model weighs approximately .60 lb (.30 kg) and uses a Viton seal kit identified by part number: 990011006.

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.
