The Sun Hydraulics DPCNLEN (DPCNLEN) is a normally closed, pilot-operated, 2-way directional cartridge valve designed for moderate flow circuits. This versatile valve can function independently or in conjunction with larger pilot-operated directional or logic cartridges. It operates by shifting when the pressure differential between port 1 and port 4 surpasses a predefined setting, with the option to block port 4 to prevent shifting. Port 3 serves as a work port and is subject to a maximum pressure limit of 3000 psi (210 bar) due to fatigue strength considerations. The DPCNLEN is not bistable and can modulate between two positions. This valve features Sun's floating style construction, which reduces the risk of internal component binding from excessive installation torque or machining variations in cavity/cartridge designs. The valve fits T-22A cavities and belongs to Series 2, accommodating a capacity of up to 15 gpm (60 L/min). Factory pressure settings are established at a flow rate of 4 gpm (15 L/min), with a 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), while maximum valve leakage at 110 SUS (24 cSt) is limited to 1 in\u00b3/min/1000 psi (15 cc/min/70 bar). Adjustments are made via an internal hex screw with up to five clockwise turns needed for increased settings, secured by a locknut that requires a torque of 80-90 lbf\u00b7in (9-10 Nm). The valve's installation torque is recommended between 45-50 lbf\u00b7ft (61-68 Nm), and it weighs approximately .60 lb (.30 kg). A Viton seal kit is available under part number 990022006 for maintenance purposes.

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 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.
