The Sun Hydraulics DPBMCDV (DPBMCDV) is a normally open, pilot-operated, 2-way directional cartridge valve designed for moderate flow circuits. This versatile component can function independently or in conjunction with larger pilot-operated directional or logic cartridges. The valve operates by shifting when the pressure differential between port 1 and port 4 exceeds its preset value. Notably, port 4 can be blocked to prevent shifting, and port 3 may serve as a work port, with a maximum pressure limit of 3000 psi (210 bar) due to fatigue strength considerations. Direct-acting and pilot-operated versions are interchangeable, sharing the same cavities and flow paths. Incorporating Sun's floating style construction, this valve minimizes the risk of internal parts binding from excessive installation torque or machining variations. It is capable of modulating between two positions but is not bistable. When pilot pressure surpasses the valve setting, pilot flow may become significant; thus, consulting performance curves for pilot consumption versus load pressure is recommended. The DPBMCDV features a T21A cavity with a series capacity of 7 gpm (28 L/min) and factory pressure settings established at 4 gpm (15 L/min). The maximum operating pressure is 5000 psi (350 bar), with control pilot flow ranging from 7 to 10 in\u00b3/min (0.11 to 0.16 L/min). Valve leakage at maximum conditions is limited to 1 in\u00b3/min (1000 psi or approximately 15 cc/min at 70 bar). Adjustments can be made via an internal hex screw with specific torque requirements for installation and locknut components. The model weighs .60 lb (0.30 kg) and includes a Viton seal kit option for enhanced durability in various applications.

Normally open, 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 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.
