The Sun Hydraulics DRBMCSN (DRBMCSN) is a normally open, direct-acting, 2-way directional cartridge valve designed for moderate flow circuits. This versatile component can operate independently or trigger larger pilot-operated directional or logic cartridges. The valve activates when the pressure differential between port 1 and port 4 surpasses a predetermined setting. Port 3 serves as a work port, with a bidirectional flow path between ports 2 and 3. Thanks to its direct-acting design, this cartridge boasts low internal leakage and minimal pilot flow consumption. It is interchangeable with pilot-operated versions, sharing the same cavities and flow paths. The pressure at port 4 directly adds to the valve setting, allowing for modulation between two positions rather than bistable operation. The maximum pressure at port 3 should be restricted to 3000 psi due to fatigue strength constraints rather than hydraulic limits. This model incorporates Sun's floating style construction to reduce the risk of internal binding from excessive installation torque or machining variations in cavity/cartridge interfaces. It fits T21A cavities within series 1 and has a capacity of up to 7 gpm (28 L/min), with factory pressure settings determined at 4 gpm (15 L/min). The DRBMCSN supports a maximum operating pressure of up to 5000 psi (350 bar) and maintains maximum valve leakage at only 2 in\u00b3/min (30 cc/min) at an oil viscosity of 110 SUS (24 cSt). Adjustments can be made with up to five clockwise turns to increase settings, using an internal hex size of 5/32 in (4 mm). With a valve hex size of 7/8 in (22.2 mm) and installation torque ranging from 30-35 lbf ft (41-47 Nm), this robust component weighs .55 lb (.25 kg) and includes Viton seal kits for enhanced durability.

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.
