The Sun Hydraulics DPCDLDN (DPCDLDN) is a pilot-operated, 3-way directional cartridge valve designed for moderate flow circuits, with a configuration of 1 to 2 open and 3 blocked. It can be used independently or to actuate larger pilot-operated directional or logic cartridges. The valve operates by shifting when the pressure differential between port 1 and port 3 surpasses its set threshold. Notably, pressure at port 3 directly influences the valve's setting, making it potentially unsuitable as a work port unless using a four-port version of this valve. This model is interchangeable with direct-acting versions, sharing cavity compatibility and flow paths. Port 3 can be blocked to prevent shifting, but the valve is not bistable and can modulate between two positions. The maximum pressure at port 3 should not exceed 3000 psi (210 bar) due to fatigue strength limits. When pilot pressure exceeds the setting, pilot flow may become a consideration; in such cases, opting for the direct-acting version might be beneficial. The valve features Sun's floating style construction to reduce internal part binding risks from excessive installation torque or machining variations. Technical specifications include a T2A cavity with series 2 capacity of up to 15 gpm (60 L/min), factory pressure settings established at 4 gpm (15 L/min), and maximum operating pressure of 5000 psi (350 bar). Control pilot flow ranges from 10 to 15 in\u00b3/min (0.16 to 0.25 L/min), with maximum leakage at specified conditions being about 1 in\u00b3/min per 1000 psi (15 cc/min per 70 bar). Adjustment requires up to five clockwise turns, with specific torque values for installation and locknut adjustments provided for precision assembly.

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.
