The Sun Hydraulics DRBMOAV (DRBMOAV) is a normally open, direct-acting, 2-way directional cartridge valve designed for moderate flow circuits. This versatile component functions as a switching device and can be used independently or 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 its set threshold, with port 3 available for use as a work port. Its bidirectional flow path between port 2 and port 3 enhances its functionality in various applications. The direct-acting design of the DRBMOAV ensures low internal leakage and minimal pilot flow consumption, making it efficient for hydraulic systems. It is interchangeable with pilot-operated versions, sharing the same cavity fit and flow paths, which offers flexibility in system design. The pressure at port 4 directly adds to the valve's setting, allowing precise control over its operation. Although not bistable, the valve can modulate between two positions based on system demands. With a maximum operating pressure of 5000 psi (350 bar) and a capacity of handling up to 7 gpm (28 L/min), this cartridge is robust enough for demanding applications while maintaining reliability through Sun's floating style construction that minimizes binding risks due to installation torque or machining variations. The maximum safe pressure at port 3 is limited to 3000 psi (210 bar) due to fatigue strength constraints. Installation requires attention to specific torque settings: the valve hex size is 7/8 in. (22.2 mm), with an installation torque of 30\u201335 lbf ft (41\u201347 Nm). Adjustments are made via an internal hex screw sized at 5/32 in. (4 mm), with locknut adjustments requiring a torque of 80\u201390 lbf in. (9\u201310 Nm). The DRBMOAV model weighs .55 lb (.25 kg) and utilizes Viton seal kits for reliable sealing performance.

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.
