The Sun Hydraulics DRBDKWN (DRBDKWN) is a direct-acting, 3-way directional cartridge valve designed for moderate flow circuits. This model features a 1 to 2 open, 3 blocked configuration and is commonly used to actuate larger pilot-operated directional or logic cartridges. The valve operates by shifting when the pressure differential between port 1 and port 3 exceeds the set threshold, with pressure at port 3 directly adding to the valve's setting. It's important to note that port 3 may not be suitable as a work port in certain circuits; if this is a concern, a four-port version of the valve could be considered as an alternative solution. The DRBDKWN boasts low internal leakage and minimal pilot flow consumption due to its direct-acting design. It offers interchangeability with pilot-operated versions, fitting the same cavities and sharing identical flow paths. Notably, this valve is not bistable but can modulate between its two positions. The construction incorporates Sun's floating style design to reduce risks of internal binding from excessive installation torque or cavity machining variations. Key specifications include a cavity size of T-11A, series 1 designation, and a capacity of up to 7 gpm (28 L/min). The factory pressure settings are established at a flow rate of 4 gpm (15 L/min), with a maximum operating pressure capability of up to 5000 psi (350 bar). The maximum allowable valve leakage at 110 SUS (24 cSt) is limited to 2 in\u00b3/min (30 cc/min). Adjustment settings can be fine-tuned with up to five clockwise turns, using an adjustment screw with an internal hex size of 5/32 inch (4 mm). Installation requires specific torque values for both the valve and locknut components. This robust component weighs approximately .60 lb (.30 kg) and includes 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 3 exceeds the setting.
- Pressure at port 3 is directly additive to the setting of the valve. Because of this, port 3 may not be useable as a work port in your circuit. If this is a consideration, the 4 port version of this valve may be a solution.
- 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.
- This valve is not bistable; it is capable of modulating between the two positions shown.
- 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.
