The Sun Hydraulics DPCBLBN (DPCBLBN) is a normally closed, pilot-operated, 2-way directional cartridge valve designed for moderate flow circuits. It serves as a switching device that 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 exceeds a predefined setting, with pressure at port 3 being directly additive to this setting. It\u2019s important to note that port 3 should not exceed a maximum pressure of 3000 psi (210 bar) due to fatigue strength limits. This valve is capable of modulating between two positions but is not bistable. The DPCBLBN features Sun's floating style construction, which minimizes the risk of internal parts binding due to installation torque or machining variations. It fits the T2A cavity and belongs to Series 2 with a capacity of up to 15 gpm (60 L/min). Factory pressure settings are established at 4 gpm (15 L/min), and it can handle a maximum operating pressure of up to 5000 psi (350 bar). Control pilot flow ranges from 10 to 15 in\u00b3/min (0.16 - 0.25 L/min), and maximum valve leakage is limited to 1 in\u00b3/min at 110 SUS (24 cSt) under conditions of up to 1000 psi (70 bar). For adjustments, the valve requires up to five clockwise turns to increase the setting, featuring a hex size of 1-1/8 inches (28.6 mm) for installation torque between 45 - 50 lbf ft (61 -68 Nm). The adjustment screw has an internal hex size of 5/32 inches (4 mm), and its locknut requires torque between 80 -90 lbf in. (9 -10 Nm). Weighing just .60 lb (.30 kg), it comes with an optional Viton seal kit for added durability 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.
- 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.
