The Sun Hydraulics DRBOKWV (DRBOKWV) is a direct-acting, 3-way directional cartridge valve designed for moderate flow circuits. This versatile component can function independently or be used to control larger pilot-operated directional or logic cartridges, making it suitable for a wide range of hydraulic applications. The valve operates by shifting when the pressure differential between port 1 and port 4 exceeds its set threshold, allowing for efficient modulation between two positions without being bistable. It features bidirectional flow paths between ports 1 and 2, as well as ports 2 and 3, with port 3 serving as a potential work port. This model's direct-acting design ensures minimal internal leakage and low pilot flow consumption. The DRBOKWV is engineered to fit the T21A cavity and belongs to Series 1 with a capacity of handling up to 7 gpm (28 L/min). It operates optimally at factory pressure settings established at a flow rate of 4 gpm (15 L/min) and can withstand a maximum operating pressure of 5000 psi (350 bar). The valve's construction incorporates Sun's floating style design, which minimizes the risk of binding due to installation torque or machining variations in the cavity/cartridge interface. The maximum allowable pressure at port 3 is limited to 3000 psi (210 bar), adhering to fatigue strength limits rather than hydraulic operating constraints. Additional specifications include an adjustment range that allows an increase in setting with up to 5.5 clockwise turns, a valve hex size of .78 inches (22.2 mm), and an installation torque requirement of 30-35 lbf ft (41-47 Nm). The DRBOKWV model weighs approximately .55 lb (.25 kg) and utilizes Viton seal kits for optimal performance.

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 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.
