The Sun Hydraulics DPBALEV (DPBALEV) is a normally open, pilot-operated, 2-way directional cartridge valve designed for moderate flow circuits. This versatile component can operate independently or be used to actuate larger pilot-operated directional or logic cartridges. The valve functions by shifting when the pressure differential between port 1 and port 3 surpasses the pre-set threshold, with pressure at port 3 being directly additive to this setting. It is important to note that port 3 may not be suitable as a work port in certain circuits, suggesting that a four-port version might be more appropriate in such cases. The DPBALEV model incorporates Sun's floating style construction, which helps minimize potential binding of internal parts due to excessive installation torque or variations in cavity/cartridge machining. This valve is capable of modulating between two positions and is not bistable. It has a maximum operating pressure of 5000 psi (350 bar) and should limit the maximum pressure at port 3 to 3000 psi (210 bar) due to fatigue strength constraints. The cartridge fits into a T-11A cavity and has a capacity of handling up to 7 gpm (28 L/min). Factory pressure settings are established at a flow rate of 4 gpm (15 L/min). The control pilot flow ranges from 7 to 10 in\u00b3/min (0.11 - 0.16 L/min), with maximum valve leakage at specified conditions being limited to 1 in\u00b3/min (15 cc/min). For adjustments, it requires up to five clockwise turns, with specific torque requirements for installation and locknut adjustments. The DPBALEV weighs approximately .60 lb (.30 kg) and uses Viton seal kits for optimal performance and durability.

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.
