The Sun Hydraulics DPCBLDN (Material Number: DPCBLDN) is a normally closed, pilot-operated, 2-way directional cartridge valve designed for moderate flow circuits. It functions as a switching device and can be used independently or 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 preset value, with pressure at port 3 directly adding to the valve's setting. Due to this feature, port 3 may not be suitable as a work port in certain circuit designs; if so, a four-port version of this valve may serve as an alternative. Both direct-acting and pilot-operated versions of these valves are interchangeable, fitting the same cavities with identical flow paths. The DPCBLDN is not bistable but can modulate between two positions. This valve incorporates Sun's floating style construction, minimizing internal part binding risks due to excessive installation torque or cavity/cartridge machining variations. It features a cavity type T2A and belongs to series 2, with a capacity of handling up to 15 gpm (60 L/min). The 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 10-15 in\u00b3/min (0.16-0.25 L/min), while maximum valve leakage at 110 SUS (24 cSt) is limited to 1 in\u00b3/min per 1000 psi (15 cc/min per 70 bar). The adjustment mechanism allows for up to five clockwise turns to increase settings, and installation requires specific torques for both the valve and locknut components. Weighing just .60 lb (.30 kg), this model comes equipped with Viton seal kits for reliable performance under various 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.
- 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.
