The Sun Hydraulics DPBALEN (DPBALEN) 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 cartridges or logic cartridges. The valve operates by shifting when the pressure differential between port 1 and port 3 exceeds its set threshold. Notably, the pressure at port 3 directly influences the valve's setting, making it unsuitable as a work port in certain circuits unless a 4-port version is utilized. This particular model features interchangeability between direct-acting and pilot-operated versions, fitting the same cavities and maintaining identical flow paths. It is not bistable but can modulate between two positions. The DPBALEN has a maximum operating pressure of 5000 psi (350 bar) and should limit maximum pressure at port 3 to 3000 psi (210 bar) due to fatigue strength constraints. The valve incorporates Sun's floating style construction to minimize internal binding risks due to excessive installation torque or machining variations. It fits into a T-11A cavity from series 1 with a capacity of 7 gpm (28 L/min), and factory pressure settings are established at 4 gpm (15 L/min). Control pilot flow ranges from 7 to 10 in\u00b3/min (0.11 to 0.16 L/min), with maximum valve leakage at specified conditions being minimal. Adjustments for increasing settings require up to five clockwise turns, with specific hex sizes for the valve body and adjustment screw provided for installation ease. The model weighs approximately .60 lb (0.30 kg) and uses Viton seal kits for maintenance purposes.

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.
