The Sun Hydraulics DRBMOBV (DRBMOBV) is a normally open, direct-acting, 2-way directional cartridge designed for moderate flow circuits. It serves 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, with port 3 available for use as a work port. Notably, the flow path between ports 2 and 3 is bidirectional, enhancing its versatility in various applications. Due to its direct-acting design, this cartridge boasts low internal leakage and minimal pilot flow consumption. It features interchangeable capabilities with pilot-operated versions, fitting the same cavities and maintaining identical flow paths. The valve's unique floating style construction minimizes internal part binding risks caused by excessive installation torque or machining variations in cavities or cartridges. The DRBMOBV operates within a maximum pressure of 5000 psi (350 bar) and has a capacity of 7 gpm (28 L/min). Factory pressure settings are established at 4 gpm (15 L/min), with maximum valve leakage at 110 SUS (24 cSt) being 2 in\u00b3/min (30 cc/min). Adjustments to increase settings require approximately 5-5 turns clockwise. Installation specifications include a valve hex size of 7/8 inch (22.2 mm) and an installation torque range of 30-35 lbf ft (41-47 Nm). The adjustment screw has an internal hex size of 5/32 inch (4 mm), while the locknut hex size is set at 9/16 inch (15 mm) with a locknut torque of 80-90 lbf in (9-10 Nm). Weighing .55 lb (.25 kg), this model includes a Viton seal kit under part number 990021006 for enhanced durability and performance in demanding environments.

Normally open, 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.
