The Sun Hydraulics DPBMCEV (DPBMCEV) is a normally open, pilot-operated, 2-way directional cartridge valve designed for moderate flow circuits. It functions as a switching device and can be used independently or to actuate larger pilot-operated directional or logic cartridges. The valve operates by shifting when the pressure differential between port 1 and port 4 exceeds its set threshold. Port 4 can be blocked to maintain the valve's position, and port 3 serves as a work port with a maximum pressure limit of 3000 psi due to fatigue strength constraints. This valve is capable of modulating between two positions rather than being bistable. The DPBMCEV incorporates Sun's floating style construction, reducing the risk of internal component binding from excessive installation torque or machining variations in the cavity/cartridge. It fits into T21A cavities and belongs to series 1 with a capacity of handling up to 7 gpm (28 L/min). The factory pressure settings are established at a flow rate of 4 gpm (15 L/min), while the maximum operating pressure is rated at 5000 psi (350 bar). Control pilot flow ranges from 7 to 10 in\u00b3/min (0.11 to 0.16 L/min), with maximum valve leakage at specified conditions being limited to 1 in\u00b3/min (15 cc/min). For installation, the valve requires a torque of 30-35 lbf ft (41-47 Nm) and features an adjustment screw with an internal hex size of ^5\u204432 inch (4 mm). The locknut has a hex size of ^9\u204416 inch (15 mm) and should be torqued within the range of 80-90 lbf in. The model weighs approximately .60 lb (.30 kg) and uses Viton seals available in kit number 990021006 for maintenance purposes.

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.
