The Sun Hydraulics DPCDKDV (DPCDKDV) is a pilot-operated, 3-way directional cartridge valve designed for moderate flow circuits. This valve facilitates switching between positions with ports 1 to 2 open and port 3 blocked, making it suitable for standalone use or in conjunction with larger pilot-operated or logic cartridges. The valve operates by shifting when the pressure differential between port 1 and port 3 exceeds a predetermined setting, with pressure at port 3 directly affecting the valve setting. However, due to its design, port 3 may not be suitable as a work port in certain circuits\u2014a consideration that could be addressed by opting for the valve's 4-port variant. The DPCDKDV is interchangeable with both direct-acting and other pilot-operated valves as they share cavity compatibility and flow paths. It is not bistable but can modulate between its two defined positions. The maximum allowable pressure at port 3 is limited to 3000 psi (210 bar) due to fatigue strength limits rather than hydraulic operating constraints. When pilot pressure surpasses the valve's setting, pilot flow becomes a consideration; if problematic, a direct-acting version of this valve might be more appropriate. Constructed using Sun's floating style design, the DPCDKDV minimizes risks of internal part binding due to excessive installation torque or machining variations in cavity/cartridge interfaces. It fits into cavity T-2A and has a capacity of up to 15 gpm (60 L/min), with maximum operating pressures reaching up to 5000 psi (350 bar). Factory pressure settings are established at a flow rate of 4 gpm (15 L/min). The valve features an adjustment mechanism allowing up to five clockwise turns to increase settings, alongside specified torque requirements for installation and adjustment components.

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 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.
- Port 3 can be blocked to prevent the valve from shifting.
- 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.
