The Sun Hydraulics DRBCKWN (DRBCKWN) is a direct-acting, 3-way directional cartridge valve designed for moderate flow circuits. It features one blocked port and an open path from port 2 to port 3, shifting when the pressure differential between ports 1 and 3 exceeds the set threshold. This valve is well-suited for applications requiring low internal leakage and minimal pilot flow consumption, thanks to its direct-acting design. It can be used independently or to actuate larger pilot-operated directional or logic cartridges, making it versatile in various hydraulic systems. This model incorporates Sun's floating style construction, reducing the risk of internal parts binding due to excessive installation torque or machining variations. The valve is not bistable; it modulates between two positions as needed. With a cavity size of T-11A and a series designation of 1, the DRBCKWN has a capacity of 7 gpm (28 L/min) and operates at a maximum pressure of 5000 psi (350 bar). The factory pressure settings are established at a flow rate of 4 gpm (15 L/min), ensuring reliable performance under specified conditions. The maximum valve leakage at 110 SUS (24 cSt) is limited to 2 in\u00b3/min (30 cc/min), maintaining efficiency in operation. Adjustments to increase pressure settings require up to five clockwise turns, with specific dimensions provided for installation and adjustment tools. The valve's hex size is .78 inches (22.2 mm), with an installation torque range of 30 to 35 lbf ft (41 to 47 Nm). Additionally, it includes an adjustment screw internal hex size of .532 inches (4 mm) and a locknut hex size of .916 inches (15 mm), with locknut torque specifications ranging from 80 to 90 lbf in (9 to 10 Nm). With a weight of .60 lb (.30 kg), this model also supports Viton seal kits for enhanced durability in demanding environments.

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.
