The Sun Hydraulics DRBMLSN (DRBMLSN) is a normally open, direct-acting, 2-way directional cartridge valve designed for moderate flow circuits. This versatile component can operate independently or actuate larger pilot-operated directional or logic cartridges. The valve transitions when the pressure differential between port 1 and port 4 exceeds its setting, while port 3 can be utilized as a work port. Featuring a bidirectional flow path between ports 2 and 3, the design ensures low internal leakage and minimal pilot flow consumption. Direct-acting and pilot-operated versions are interchangeable, sharing cavity compatibility and flow paths. The pressure at port 4 directly influences the valve setting, allowing modulation between two positions rather than bistability. Maximum pressure at port 3 should not exceed 3000 psi (210 bar) due to fatigue strength limits. The valve incorporates Sun's floating style construction to minimize internal binding risks from excessive installation torque or machining variations. Key specifications include a T21A cavity, Series 1 classification, and a capacity of 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). Maximum valve leakage is rated at 2 in\u00b3/min (30 cc/min) under specific conditions. Adjustment requires up to five clockwise turns to increase settings, with precise dimensions for hex sizes and installation torque provided for optimal setup: Valve Hex Size is .78 in. (22.2 mm), Installation Torque ranges from 30 to 35 lbf ft (41 to 47 Nm), Adjustment Screw Internal Hex Size is .532 in. (4 mm), Locknut Hex Size is .916 in. (15 mm), and Locknut Torque ranges from 80 to 90 lbf in. (9 to 10 Nm). The model weighs .55 lb (.25 kg) and uses Viton seal kits for maintenance reliability.

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.
