The Sun Hydraulics DPCBLWN (DPCBLWN) is a normally closed, pilot-operated, 2-way directional cartridge valve designed for moderate flow circuits. This versatile component 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 a predetermined setting, with pressure at port 3 being directly additive to the setting. However, it's important to note that port 3 might not be suitable as a work port in certain circuits; in such cases, a 4-port version could be considered. The DPCBLWN is not bistable and can modulate between two positions, making it adaptable for various applications. This valve fits the T2A cavity and belongs to Series 2, with a capacity of handling up to 15 gpm (60 L/min). It is factory set at a pressure established at 4 gpm (15 L/min), with a maximum operating pressure of up to 5000 psi (350 bar). Control pilot flow ranges from 10 to 15 in\u00b3/min (0.16 to 0.25 L/min), while maximum valve leakage is limited to 1 in\u00b3/min at 1000 psi (15 cc/min at 70 bar). The DPCBLWN features Sun's floating style construction, which minimizes internal binding due to excessive installation torque or machining variations. The valve's dimensions include a hex size of 1-1/8 inches (28.6 mm) and an installation torque requirement of between 45 and 50 lbf\u00b7ft (61 and 68 Nm). Adjustment is achieved via an internal hex screw sized at 5/32 inches (4 mm), with locknut torque specifications ranging from 80 to 90 lbf\u00b7in (9 to10 Nm). Weighing approximately .60 lb (.30 kg), this model also includes a Viton seal kit option for enhanced durability and 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.
- 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.
