The Sun Hydraulics DPCPLWV (DPCPLWV) is a pilot-operated, 3-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 the pre-set threshold. Notably, port 4 can be blocked to inhibit shifting, while port 3 serves as a work port, with a maximum allowable pressure of 3000 psi (210 bar) due to fatigue strength constraints. The valve's construction allows for interchangeability between direct-acting and pilot-operated versions, fitting the same cavities and maintaining identical flow paths. The DPCPLWV incorporates Sun's floating style construction to reduce the risk of internal part binding from excessive installation torque or variations in cavity and cartridge machining. It features a cavity size of T22A, belongs to series 2, and has a capacity of 15 gpm (60 L/min). The factory pressure settings are established at 4 gpm (15 L/min), with a maximum operating pressure of up to 5000 psi (350 bar). Control pilot flow ranges between 10-15 in\u00b3/min (0.16-0.25 L/min), while maximum valve leakage at 110 SUS (24 cSt) is limited to 1 in\u00b3/min at 1000 psi (15 cc/min at 70 bar). Adjustment settings include up to five clockwise turns for increasing the setting, with specific torque requirements for installation and adjustments: valve installation torque is set between 45-50 lbf ft (61-68 Nm), adjustment screw internal hex size is ^5/32 in. (4 mm), locknut hex size is ^9/16 in. (15 mm), and locknut torque ranges from 80-90 lbf in. (9-10 Nm). The model weighs approximately .60 lb (.30 kg) and utilizes Viton seal kits for optimal performance.

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.
