The Sun Hydraulics DPBCLBN (DPBCLBN) is a pilot-operated, 3-way directional cartridge valve designed for moderate flow circuits. It serves as a switching device, allowing one port to be blocked while opening the flow between the other two ports. This valve is particularly useful in applications where it can operate independently or actuate larger pilot-operated or logic cartridges. The valve shifts when the pressure differential between port 1 and port 3 surpasses its set threshold, with pressure at port 3 directly adding to this setting. Notably, if port 3 is intended for work purposes in your circuit, a 4-port version may be more suitable due to these dynamics. This model incorporates Sun's floating style construction to reduce potential internal binding from excessive torque or machining variations. It fits into cavity T-11A and belongs to series 1, offering a capacity of up to 7 gpm (28 L/min) with a maximum operating pressure of 5000 psi (350 bar). The factory settings are established at a flow rate of 4 gpm (15 L/min), and it features control pilot flows ranging from 7 to 10 in\u00b3/min (0.11 to 0.16 L/min). Valve leakage at standard viscosity conditions measures at a maximum of 1 in\u00b3/min (15 cc/min) under pressures up to 1000 psi (70 bar). Additional specifications include an adjustment range facilitated by up to five clockwise turns, installation torque requirements between 30-35 lbf-ft (41-47 Nm), and an overall model weight of approximately .60 lb (0.30 kg). The DPBCLBN is not bistable but can modulate between positions based on pilot pressure exceeding its setpoint, with potential implications for pilot flow consumption under high load pressures.

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.
