The Sun Hydraulics DPCPLDV (DPCPLDV) is a pilot-operated, 3-way directional cartridge valve designed for moderate flow circuits, offering versatility in hydraulic applications. This valve is engineered to operate by shifting when the pressure differential between port 1 and port 4 exceeds a predefined setting. It features an innovative design where port 4 can be blocked to prevent shifting, and port 3 can function as a work port. The valve is capable of modulating between two positions rather than being bistable, providing flexibility in control. With a maximum operating pressure of 5000 psi (350 bar) and a capacity of 15 gpm (60 L/min), it ensures robust performance under demanding conditions. The DPCPLDV incorporates Sun's floating style construction to minimize internal binding due to excessive installation torque or machining variations. It fits into cavity T22A and belongs to series 2, ensuring compatibility with other valves in the same series. The valve's factory pressure settings are established at a flow rate of 4 gpm (15 L/min), with the maximum leakage at 110 SUS (24 cSt) being limited to 1 in\u00b3/min at 1000 psi (15 cc/min at 70 bar). Adjustment is facilitated by an internal hex screw with specific torque requirements for both the adjustment screw and locknut. This cartridge valve is suitable for applications where precise modulation between positions is necessary, offering reliable control over hydraulic flow paths. Its pilot-operated nature makes it ideal for use in systems requiring moderate speed adjustments with low pressure rise versus flow curve characteristics. For enhanced performance, consideration should be given to pilot consumption relative to load pressure above the valve setting.

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.
