The Sun Hydraulics DRBMOWN (DRBMOWN) is a normally open, direct-acting, 2-way directional cartridge valve designed for moderate flow circuits. This versatile component can function independently or be used to actuate larger pilot-operated directional or logic cartridges. The valve operates by shifting when the pressure differential between port 1 and port 4 surpasses its preset level. Port 3 serves as a work port, with bidirectional flow possible between ports 2 and 3. Thanks to its direct-acting design, the cartridge features minimal internal leakage and low pilot flow consumption, making it efficient in various applications. Notably, direct-acting and pilot-operated versions of these valves are interchangeable, fitting the same cavities and maintaining identical flow paths. The pressure at port 4 directly contributes to the valve's setting, allowing for modulation between two positions rather than binary operation. The maximum pressure at port 3 is limited to 3000 psi (210 bar) due to fatigue strength constraints rather than hydraulic operating limits. The DRBMOWN incorporates Sun's floating style construction, reducing the risk of internal components binding from excessive installation torque or machining variations in the cavity/cartridge interface. It fits into a T21A cavity with a series capacity of up to 7 gpm (28 L/min) and factory pressure settings established at a flow rate of 4 gpm (15 L/min). The valve can handle a maximum operating pressure of up to 5000 psi (350 bar), with maximum leakage limited to 2 in\u00b3/min (30 cc/min) at an oil viscosity of 110 SUS (24 cSt). For installation and adjustment, it features specific hex sizes for both valve body and adjustment screw operations, ensuring precise control over performance settings.

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.
