The Sun Hydraulics DRBCKDN (DRBCKDN) is a direct-acting, 3-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 3 surpasses its set threshold, with pressure at port 3 directly adding to the setting. Due to this design, port 3 may not always be suitable as a work port; in such cases, a 4-port version might be more appropriate. The DRBCKDN's direct-acting design ensures low internal leakage and minimal pilot flow consumption, making it efficient in various applications. It is interchangeable with pilot-operated versions, sharing the same cavities and flow paths. However, it is not bistable and can modulate between two positions. This valve features Sun's floating style construction to reduce the risk of internal parts binding from excessive installation torque or machining variations. It fits into a T-11A cavity and has a capacity of 7 gpm (28 L/min). Factory pressure settings are established at 4 gpm (15 L/min), with a maximum operating pressure of up to 5000 psi (350 bar). The valve exhibits maximum leakage of 2 in\u00b3/min (30 cc/min) at 110 SUS (24 cSt). For adjustments, the screw requires approximately five turns clockwise to increase the setting. The hex size for installation is 7/8 inch (22.2 mm), with an installation torque range of 30 - 35 lbf ft (41 - 47 Nm). The adjustment screw has an internal hex size of 5/32 inch (4 mm), while the locknut hex size is 9/16 inch (15 mm) with a torque specification of 80 - 90 lbf in (9 -10 Nm). This model weighs approximately .60 lb (.30 kg) and utilizes Viton seals for enhanced durability.

Direct-acting, 3-way directional cartridges (1 blocked, 2 to 3 open) 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.
