The Sun Hydraulics DPBBLAV (DPBBLAV) is a normally closed, pilot-operated, 2-way directional cartridge valve designed for moderate flow circuits. It 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 surpasses the set threshold. Notably, pressure at port 3 directly adds to the valve's setting, which may restrict its use as a work port in some circuits; in such cases, a four-port version might be more suitable. This valve is not bistable and can modulate between two positions depending on pilot pressure exceeding the valve setting. For circuits where pilot flow becomes an issue, considering the direct-acting version could be beneficial. The DPBBLAV incorporates Sun's floating style construction to reduce risks of internal binding caused by excessive installation torque or cavity/cartridge machining variations. It fits into cavity T-11A and belongs to Series 1 with a capacity of 7 gpm (28 L/min). The factory pressure settings are established at 4 gpm (15 L/min), with 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 to 0.16 L/min), and maximum valve leakage at 110 SUS (24 cSt) is rated at 1 in\u00b3/min/1000 psi (15 cc/min/70 bar). The adjustment for increasing settings requires approximately five full clockwise turns, with specific torque values provided for installation and locknut adjustments. This model weighs approximately .60 lb (0.30 kg) and uses Viton seal kits for effective performance under varying conditions.

Normally closed, 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.
- 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.
