The Sun Hydraulics DPBMCJN (DPBMCJN) is a normally open, pilot-operated, 2-way directional cartridge valve designed for moderate flow circuits. This versatile valve can be utilized independently or in conjunction with larger pilot-operated directional cartridges or logic cartridges. It operates by shifting when the pressure differential between port 1 and port 4 surpasses the preset threshold. Notably, port 4 can be blocked to prevent shifting, while port 3 serves as a work port. The valve is capable of modulating between two positions and incorporates Sun's floating style construction to minimize internal binding due to installation torque or machining variations. With a maximum operating pressure of 5000 psi (350 bar) and a capacity of 7 gpm (28 L/min), this valve fits into a T-21A cavity and maintains interchangeability with direct-acting versions. The DPBMCJN has several key specifications: it is factory pressure set at 4 gpm (15 L/min), allows for control pilot flow between 7 - 10 in\u00b3/min (0.11 - 0.16 L/min), and limits maximum valve leakage at 110 SUS (24 cSt) to 1 in\u00b3/min at 1000 psi (15 cc/min at 70 bar). For adjustments, the valve requires up to five clockwise turns to increase setting, utilizing an adjustment screw with an internal hex size of 5/32 in. (4 mm). Installation torque ranges from 30 - 35 lbf ft (41 - 47 Nm), while locknut torque is specified at 80 - 90 lbf in. (9 -10 Nm). The model weighs approximately .60 lb (.30 kg) and uses Viton seal kit number: 990021006. This cartridge's robust design makes it suitable for applications requiring reliable modulation between two states without bistable characteristics, ensuring efficient performance even under varying conditions.

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.
