The Sun Hydraulics DPBCLBV (DPBCLBV) is a pilot-operated, 3-way directional cartridge valve designed for moderate flow circuits. This versatile valve can function independently or be used to actuate larger pilot-operated directional or logic cartridges. It features a unique shifting mechanism that activates when the pressure differential between port 1 and port 3 exceeds a predetermined setting, with the added capability of adjusting pressure at port 3 directly. However, due to this feature, port 3 may not be suitable as a work port in some circuits; if necessary, a 4-port version may be more appropriate. The valve is interchangeable with direct-acting versions, fitting the same cavities and maintaining identical flow paths. One notable characteristic of the DPBCLBV is its ability to modulate between two positions rather than being bistable. This modulation requires consideration of pilot flow when pilot pressure surpasses the valve setting\u2014an aspect addressed by consulting performance curves for pilot consumption versus load pressure above the valve setting. If pilot flow becomes problematic, switching to a direct-acting version could provide a solution. Constructed with Sun's floating style design, this cartridge minimizes potential internal binding due to excessive installation torque or machining variations. It fits into cavity T-11A and has a capacity of 7 gallons per minute (28 liters per minute), with factory pressure settings established at 4 gallons per minute (15 liters per minute). The maximum operating pressure is rated at 5000 psi (350 bar), and it maintains low leakage rates under specified conditions. For installation, it requires specific torque settings for both the valve and locknut components. Additionally, it includes an adjustment mechanism for fine-tuning pressure settings through clockwise turns.

Pilot-operated, 3-way directional cartridges (1 blocked, 2 to 3 open) 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.
- 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.
