The Sun Hydraulics DPBALCV (DPBALCV) 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 shifts when the pressure differential between port 1 and port 3 exceeds its preset value. Notably, pressure at port 3 directly adds to the valve setting, which means it may not be suitable as a work port unless a 4-port version is employed. The DPBALCV is not bistable; it modulates between two positions. It features Sun's floating style construction to reduce internal binding risks due to excessive installation torque or machining variations. The DPBALCV fits into a T-11A cavity and belongs to series 1, with a capacity of up to 7 gallons per minute (28 liters per minute). Factory pressure settings are established at a flow rate of 4 gallons per minute (15 liters per minute), and the maximum operating pressure reaches up to 5000 psi (350 bar). The control pilot flow ranges from 7 to 10 cubic inches per minute (0.11 to 0.16 liters per minute), while maximum valve leakage at 110 SUS (24 cSt) is limited to 1 cubic inch per minute at 1000 psi (15 cc/min at 70 bar). The valve's adjustment allows for up to five clockwise turns to increase its setting. Installation specifications include a hex size of .78 inches (22.2 mm) with an installation torque of between 30 and 35 lbf-ft (41 and 47 Nm). The adjustment screw has an internal hex size of .532 inches (4 mm), while the locknut hex size is .916 inches (15 mm), requiring a locknut torque of between 80 and 90 lbf-inches (9 and 10 Nm). Weighing approximately .60 pounds (.30 kg), the DPBALCV also offers Viton seal kits for enhanced durability in various applications.

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.
