The Sun Hydraulics DPCBLHN (DPCBLHN) is a normally closed, pilot-operated, 2-way directional cartridge valve designed for moderate flow circuits. This versatile component serves as a switching device that can function independently or 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 predefined setting, with pressure at port 3 being directly additive to this setting. However, it is important to note that port 3 may not be suitable as a work port due to this configuration; in such cases, a 4-port version may be more appropriate. This valve features interchangeable direct-acting and pilot-operated versions that fit the same cavities and share identical flow paths. It is not bistable and can modulate between two positions. Maximum pressure at port 3 should not exceed 3000 psi (210 bar) due to fatigue strength limits, although this does not affect hydraulic operating limits. For applications where pilot pressure surpasses the valve setting, pilot flow may become significant; if necessary, a direct-acting version could resolve this issue. With Sun's floating style construction, the DPCBLHN minimizes internal parts binding caused by excessive installation torque or cavity/cartridge machining variations. Key specifications include its T2A cavity design, Series 2 classification, a capacity of up to 15 gpm (60 L/min), and factory pressure settings established at 4 gpm (15 L/min). The maximum operating pressure is rated at 5000 psi (350 bar), with control pilot flow ranging from 10 to 15 in\u00b3/min (0.16 to 0.25 L/min). The valve also features an adjustment mechanism with up to five clockwise turns to increase settings and includes Viton seal kits for maintenance.

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.
