The Sun Hydraulics DRBMLAV (Material Number: DRBMLAV) is a normally open, direct-acting, 2-way directional cartridge valve designed for moderate flow circuits. It is versatile and can function independently or actuate larger pilot-operated directional cartridges or logic cartridges. This valve operates by shifting when the pressure differential between port 1 and port 4 surpasses the set threshold. Notably, port 3 serves as a work port, and the flow path between ports 2 and 3 is bidirectional. Due to its direct-acting design, the valve exhibits low internal leakage and minimal pilot flow consumption. Direct-acting and pilot-operated versions of these valves are interchangeable, fitting the same cavities with identical flow paths. The DRBMLAV model features Sun's floating style construction to reduce the risk of internal parts binding from excessive installation torque or machining variations in cavity-cartridge applications. It is capable of modulating between two positions rather than being bistable, with pressure at port 4 directly affecting the valve setting. The maximum pressure at port 3 should be limited to 3000 psi (210 bar) due to fatigue strength limits rather than hydraulic operating constraints. This cartridge fits a T21A cavity from Series 1 with a capacity of up to 7 gpm (28 L/min) and has a maximum operating pressure of 5000 psi (350 bar). The factory pressure settings are established at a flow rate of 4 gpm (15 L/min), with maximum valve leakage rated at 2 in\u00b3/min (30 cc/min) at viscosity levels of 110 SUS (24 cSt). The adjustment mechanism involves clockwise turns to increase settings, requiring specific torque values for installation and locknut adjustments. The model weighs approximately .55 lb (.25 kg) and uses Viton seal kits for optimal 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.
