The Sun Hydraulics DRBPOWN (DRBPOWN) is a direct-acting, 3-way directional cartridge valve designed for moderate flow circuits. This versatile component can function independently or be utilized to actuate 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 threshold. Port 3 is available for use as a work port, and the flow paths between ports 1 and 2, as well as ports 2 and 3, are bidirectional. Notably, this valve features low internal leakage and minimal pilot flow consumption due to its direct-acting design. One of the key advantages of this model is its interchangeability with pilot-operated versions, as they share the same cavities and flow paths. The maximum operating pressure is rated at 5000 psi (350 bar), while the maximum allowable pressure at port 3 should not exceed 3000 psi (210 bar) to maintain fatigue strength limits. The DRBPOWN incorporates Sun's floating style construction to reduce the risk of internal parts binding from excessive installation torque or cavity/cartridge machining variations. The valve has a capacity of up to 7 gpm (28 L/min) with factory pressure settings established at a flow rate of 4 gpm (15 L/min). It also features an adjustment mechanism that requires approximately five clockwise turns to increase setting, with specific torque values provided for installation and locknut adjustments. This model weighs approximately .55 lb (.25 kg) and comes equipped with Viton seal kits for enhanced durability.

Direct-acting, 3-way directional cartridges (1 to 2 open, 3 blocked) 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.
- The flow path between port 1 and port 2 is bidirectional.
- 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.
