The Sun Hydraulics DPCPKWN (DPCPKWN) is a pilot-operated, 3-way directional cartridge valve designed for moderate flow circuits. This versatile component 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 4 surpasses the preset threshold, with options to block port 4 to prevent shifting and use port 3 as a work port. Notably, this valve is not bistable and can modulate between two positions. It is interchangeable with direct-acting versions, sharing cavity compatibility and flow paths. The DPCPKWN features a maximum operating pressure of 5000 psi (350 bar) with a capacity of 15 gpm (60 L/min). Factory pressure settings are established at 4 gpm (15 L/min), while control pilot flow ranges from 10 to 15 in\u00b3/min (0.16 to 0.25 L/min). The valve incorporates Sun's floating style construction to minimize internal binding due to excessive installation torque or machining variations. Maximum pressure at port 3 should not exceed 3000 psi (210 bar) due to fatigue strength limits. Additional specifications include a cavity size of T-22A, series number of 2, and an adjustment mechanism requiring up to five clockwise turns for setting increases. Installation torque ranges from 45-50 lbf\u00b7ft (61-68 Nm), with locknut torque specified at 80-90 lbf\u00b7in (9-10 Nm). The valve's hex size is set at 1-1/8 inches (28.6 mm), with an internal hex size for adjustment screws at 5/32 inches (4 mm). A Viton seal kit is available under part number 990022006, ensuring reliable sealing performance in various applications.

Pilot-operated, 3-way directional cartridges (1 to 2 open, 3 blocked) 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 4 exceeds the setting.
- Port 4 can be blocked to prevent the valve from shifting.
- Port 3 can be used as a work port.
- Direct-acting and pilot-operated versions of these valves are interchangeable. They fit the same cavities and have the same flow paths.
- Pressure at port 4 is directly additive to the setting of the valve.
- 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.
