The Sun Hydraulics DRBNCEN (Material Number: DRBNCEN) is a normally closed, direct-acting, 2-way directional cartridge valve designed for moderate flow circuits. It functions as a switching device and can be utilized 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 surpasses the set threshold. Port 3 serves as a work port, and the flow path between ports 2 and 3 is bidirectional, offering versatility in circuit design. Thanks to its direct-acting design, this cartridge valve boasts low internal leakage and minimal pilot flow consumption, contributing to efficient operation. The DRBNCEN model is interchangeable with pilot-operated versions, sharing the same cavity fit and flow paths. Pressure at port 4 directly influences the valve setting, allowing for precise control adjustments. However, it\u2019s important to note that this valve is not bistable; it modulates between two positions based on pressure changes. The maximum pressure at port 3 should not exceed 3000 psi (210 bar) due to fatigue strength limitations. This model incorporates Sun's floating style construction to minimize potential internal part binding caused by excessive installation torque or machining variations in cavity-cartridge interfaces. It fits into a T21A cavity with a series capacity of 7 gpm (28 L/min), while factory pressure settings are established at 4 gpm (15 L/min). The DRBNCEN can withstand a maximum operating pressure of up to 5000 psi (350 bar), with maximum valve leakage at specified conditions being just 2 in\u00b3/min (30 cc/min). The adjustment mechanism allows for fine-tuning via clockwise turns to increase settings, ensuring adaptability across various applications.

Normally closed, direct-acting, 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 3 can be used as a work port.
- The flow path between port 2 and port 3 is bidirectional.
- Because of their direct-acting design, these cartridges feature low internal leakage and low pilot flow consumption.
- 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.
- 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.
