The Sun Hydraulics DPCALCN (DPCALCN) is a normally open, pilot-operated, 2-way directional cartridge valve designed for moderate flow circuits. It functions as a switching device and can be utilized independently or to actuate larger pilot-operated directional or logic cartridges. The valve activates when the pressure differential between port 1 and port 3 surpasses the set threshold. Notably, pressure at port 3 is additive to the valve's setting, which may limit its use as a work port in certain circuits; in such cases, a 4-port version may be more suitable. This model features interchangeable direct-acting and pilot-operated versions that fit identical cavities with similar flow paths. It is capable of modulating between two positions but is not bistable. The maximum pressure at port 3 should be limited to 3000 psi (210 bar) due to fatigue strength limits rather than hydraulic operating limits. The DPCALCN incorporates Sun's floating style construction to minimize potential internal binding caused by excessive installation torque or machining variations. It features a T2A cavity and belongs to Series 2 with a capacity of 15 gpm (60 L/min). 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 - 0.25 L/min), and maximum valve leakage at 110 SUS (24 cSt) is rated at 1 in\u00b3/min/1000 psi (15 cc/min/70 bar). Adjustments can be made with up to five clockwise turns, and the valve has specific installation torque requirements along with defined hex sizes for adjustment screw and locknut.

Normally open, 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.
