The Sun Hydraulics DPBALWV (DPBALWV) is a normally open, pilot-operated, 2-way directional cartridge valve designed for moderate flow circuits. This versatile component 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 3 exceeds its pre-set threshold. Notably, pressure at port 3 directly influences the valve setting, which may limit its use as a work port in certain circuits. For applications where this is a concern, a 4-port version may be more suitable. Both direct-acting and pilot-operated versions of these valves are interchangeable, fitting the same cavities and maintaining identical flow paths. The DPBALWV features Sun's floating style construction to minimize internal binding due to excessive installation torque or machining variations. The valve is capable of modulating between two positions and has a maximum operating pressure of 5000 psi (350 bar). It fits into cavity T-11A with a series capacity of 7 gpm (28 L/min) and factory pressure settings established at 4 gpm (15 L/min). The control pilot flow ranges from 7 to 10 in\u00b3/min (0.11 to 0.16 L/min), with maximum valve leakage at 110 SUS (24 cSt) being just 1 in\u00b3/min (15 cc/min) at 1000 psi (70 bar). Adjustments can be made via an internal hex adjustment screw, with up to five full clockwise turns available to increase the setting. The valve's hex size is .78 inches (22.2 mm), requiring an installation torque of between 30 and 35 lbf ft (41 to 47 Nm). It comes with Viton seal kit number: 990011006 for enhanced durability under various operational conditions.

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.
