The Sun Hydraulics DPCBCWN (DPCBCWN) 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 cartridges or logic cartridges. The valve operates by shifting when the pressure differential between port 1 and port 3 surpasses a predefined setting. Notably, pressure at port 3 adds directly to the valve's setting, which might restrict its use as a work port in certain circuits; in such cases, a four-port version may be more suitable. This valve model is not bistable and can modulate between two positions. It is interchangeable with direct-acting versions, sharing the same cavity dimensions and flow paths. The DPCBCWN features Sun's floating style construction to minimize internal part binding due to excessive installation torque or machining variations. It fits into a T-2A cavity and belongs to Series 2 with a capacity of 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). The control pilot flow ranges from 10 to 15 in\u00b3/min (0.16 to 0.25 L/min), and maximum valve leakage at 110 SUS (24 cSt) is limited to 1 in\u00b3/min/1000 psi (15 cc/min/70 bar). For adjustment purposes, increasing the setting requires approximately five full clockwise turns. The valve hex size is 1-1/8 inches (28.6 mm), with an installation torque of 45-50 lbf\u00b7ft (61-68 Nm). The adjustment screw has an internal hex size of 5/32 inches (4 mm), while the locknut hex size is 9/16 inches (15 mm) with a locknut torque of 80-90 lbf\u00b7in (9-10 Nm). The model weighs approximately .60 lb (.30 kg) and utilizes Viton seal kits for optimal performance.

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.
