The Sun Hydraulics DPCBLBV (DPCBLBV) is a normally closed, pilot-operated, 2-way directional cartridge valve designed for moderate flow circuits. This versatile component can function independently or be used 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 surpasses a specified setting. Notably, the pressure at port 3 directly adds to the valve's setting, which might limit its use as a work port in certain configurations; a 4-port version may be more suitable in such cases. Both direct-acting and pilot-operated versions of these valves are interchangeable, sharing the same cavities and flow paths. The DPCBLBV is capable of modulating between two positions but is not bistable. The maximum pressure at port 3 should not exceed 3000 psi (210 bar) due to fatigue strength constraints rather than hydraulic limits. In scenarios where pilot pressure exceeds the valve setting, pilot flow becomes crucial; if excessive, opting for the direct-acting version could resolve this issue. The valve features Sun's floating style construction to reduce internal binding risks from excessive installation torque or cavity-cartridge machining variations. Technical specifications include a T2A cavity with a series capacity of 15 gpm (60 L/min), factory pressure settings established at 4 gpm (15 L/min), and a maximum operating pressure of 5000 psi (350 bar). Control pilot flow ranges between 10-15 in\u00b3/min (0.16-0.25 L/min), with maximum leakage at 110 SUS being 1 in\u00b3/min at 1000 psi (15 cc/min at 70 bar). Adjustments can be made with up to five clockwise turns to increase settings, using an internal hex size adjustment screw of 5/32 in. (4 mm). The valve weighs .60 lb (.30 kg) and includes a Viton seal kit option for enhanced performance.

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 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.
- 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.
