The Sun Hydraulics DRBMXFN (Material Number: DRBMXFN) is a normally open, direct-acting, 2-way directional cartridge valve designed for moderate flow circuits. This versatile component can function independently or in conjunction with larger pilot-operated directional or logic cartridges. The valve operates by shifting when the pressure differential between port 1 and port 4 exceeds its set value. Notably, port 3 can serve as a work port, and the flow path between ports 2 and 3 is bidirectional. Due to its direct-acting design, the DRBMXFN boasts low internal leakage and minimal pilot flow consumption. The valve is interchangeable with pilot-operated versions, sharing the same cavity fit and flow paths. Pressure at port 4 directly adds to the valve's setting, allowing for modulation between positions rather than bistable operation. The maximum pressure at port 3 is limited to 3000 psi (210 bar) due to fatigue strength constraints. The valve features Sun's floating style construction to mitigate internal binding from excessive installation torque or machining variations. This model fits into a T-21A cavity and belongs to Series 1 with a capacity of up to 7 gpm (28 L/min). Factory pressure settings are established at a flow rate of 4 gpm (15 L/min), with a maximum operating pressure of 5000 psi (350 bar). It allows a maximum leakage of 2 in\u00b3/min (30 cc/min) at an oil viscosity of 110 SUS (24 cSt). The valve has a hex size of 7/8 in. (22.2 mm) and requires an installation torque ranging from 30 to 35 lbf ft (41 to 47 Nm). Weighing approximately .55 lb (.25 kg), it comes with a Viton seal kit available under part number: 990021006.

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.
