The Sun Hydraulics DPCPLBN (DPCPLBN) is a versatile pilot-operated, 3-way directional cartridge valve designed for moderate flow circuits. It features a configuration where ports 1 to 2 are open and port 3 is blocked, making it suitable for applications requiring controlled switching of hydraulic flow. The valve operates by shifting when the pressure differential between port 1 and port 4 exceeds a predefined setting, with the option to block port 4 to prevent shifting. Port 3 can be utilized as a work port, adding flexibility in system design. This model is interchangeable with direct-acting versions, sharing the same cavity and flow paths, which simplifies integration into existing systems. It incorporates Sun's floating style construction to minimize binding due to installation torque or machining variations. The maximum operating pressure at port 3 is limited to 3000 psi (210 bar) due to fatigue strength limits rather than hydraulic operating constraints. The DPCPLBN has a capacity of up to 15 gpm (60 L/min) and operates at a maximum pressure of 5000 psi (350 bar). Factory pressure settings are established at a flow rate of 4 gpm (15 L/min), with control pilot flow ranging from 10-15 in\u00b3/min (0.16-0.25 L/min). Leakage is minimal, with a maximum valve leakage rate of 1 in\u00b3/min at 110 SUS (24 cSt) under pressure conditions of up to 1000 psi (70 bar). Installation requires specific torque values: the valve installation torque ranges from 45-50 lbf\u00b7ft (61-68 Nm), while the adjustment screw internal hex size is set at \\( \\frac{5}{32} \\) inch (4 mm). The locknut requires a torque setting between 80-90 lbf\u00b7in (9-10 Nm). This robust valve weighs approximately .60 lb (.30 kg) and can be serviced using Viton seal kits for maintenance or replacement needs.

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.
