The Sun Hydraulics DRBNOEV (DRBNOEV) is a normally closed, direct-acting, 2-way directional cartridge valve designed for moderate flow circuits. It can function independently or be used to actuate larger pilot-operated directional cartridges or logic cartridges. The valve operates by shifting when the pressure differential between port 1 and port 4 exceeds a preset setting. Port 3 serves as a work port with a bidirectional flow path between ports 2 and 3. The direct-acting design ensures low internal leakage and low pilot flow consumption, making it an efficient choice for various applications. This model is interchangeable with pilot-operated versions, fitting the same cavities and maintaining identical flow paths. The DRBNOEV incorporates Sun's floating style construction to minimize internal part binding risks due to excessive installation torque or machining variations in the cavity or cartridge. It is capable of modulating between two positions but is not bistable. The maximum allowable pressure at port 3 is limited to 3000 psi (210 bar) due to fatigue strength limits, while the maximum operating pressure stands at 5000 psi (350 bar). The valve has a capacity of handling up to 7 gpm (28 L/min), with factory pressure settings established at 4 gpm (15 L/min). Additional specifications include a cavity size of T-21A, series number of 1, and a maximum valve leakage rate of 2 in\u00b3/min (30 cc/min) at 110 SUS (24 cSt). Installation requires a torque setting between 30 - 35 lbf ft (41 - 47 Nm), with adjustment capabilities facilitated by an internal hex size of 5/32 in. (4 mm). A locknut hex size of 9/16 in. (15 mm) and locknut torque range of 80 - 90 lbf in. (9 -10 Nm) are also specified for secure installation and adjustment management.

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.
