The Sun Hydraulics DPCDLBN (DPCDLBN) is a pilot-operated, 3-way directional cartridge valve designed for moderate flow circuits. This model features a configuration where ports 1 and 2 are open, and port 3 is blocked, making it suitable for use as a standalone device or to actuate larger pilot-operated directional cartridges or logic cartridges. The valve operates by shifting when the pressure differential between port 1 and port 3 exceeds the set threshold, with pressure at port 3 being directly additive to the valve setting. It should be noted that port 3 may not be suitable as a work port due to this characteristic. The DPCDLBN valve is interchangeable with direct-acting versions, sharing the same cavity and flow paths, and incorporates Sun's floating style construction to minimize internal binding risks. It has a maximum operating pressure of 5000 psi (350 bar) and can handle a capacity of up to 15 gpm (60 L/min). The factory pressure settings are established at a flow rate of 4 gpm (15 L/min), while control pilot flow ranges from 10 to 15 in\u00b3/min (0.16 to 0.25 L/min). This model is not bistable but can modulate between the two positions shown in its design. Maximum pressure at port 3 should be limited to 3000 psi (210 bar) due to fatigue strength limits rather than hydraulic operating limits. If pilot flow becomes an issue when exceeding valve settings, switching to the direct-acting version may be necessary. The DPCDLBN also includes specific installation requirements, such as torque specifications for both the valve and locknut, ensuring proper setup and operation within hydraulic systems.

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.
