The Sun Hydraulics DPBBLKV (DPBBLKV) is a normally closed, pilot-operated, 2-way directional cartridge valve designed for moderate flow circuits. This versatile valve can function independently or be used to actuate larger pilot-operated directional cartridges or logic cartridges. It operates by shifting when the pressure differential between port 1 and port 3 exceeds a preset threshold. Notably, the pressure at port 3 directly adds to the valve's setting, which may restrict its use as a work port in certain circuits. For such scenarios, a 4-port version of this valve might be more suitable. The DPBBLKV is interchangeable with direct-acting versions, sharing cavity compatibility and flow paths. This model is not bistable and can modulate between two positions based on pilot pressure exceeding its setting. In cases where pilot flow becomes significant above the valve setting, switching to a direct-acting version might be beneficial. Sun's floating style construction minimizes internal binding risks due to installation torque or machining variations. Key specifications include a T11A cavity, Series 1 designation, and a capacity of 7 gpm (28 L/min). Factory pressure settings are established at 4 gpm (15 L/min), with a maximum operating pressure of 5000 psi (350 bar). Control pilot flow ranges from 7 to 10 in\u00b3/min (0.11 to 0.16 L/min), while maximum leakage at standard conditions is limited to 1 in\u00b3/min (15 cc/min). The valve features an adjustment mechanism allowing up to five clockwise turns for setting increases and requires specific installation torque values for optimal performance. Weighing .60 lb (0.30 kg), it includes Viton seal kits for reliable operation in various applications.

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.
