The Sun Hydraulics DRBOOAN (Material Number: DRBOOAN) is a direct-acting, 3-way directional cartridge valve designed for moderate flow circuits. This particular model features one blocked port and an open bidirectional flow path between ports 2 and 3. It is versatile in its application, capable of functioning independently or in conjunction with larger pilot-operated or logic cartridges. The valve operates by shifting when the pressure differential between port 1 and port 4 surpasses a predetermined setting, with pressure at port 4 being directly additive to the valve's setting. Port 3 can be utilized as a work port, but it is important to limit its maximum pressure to 3000 psi (210 bar) due to fatigue strength constraints. The DRBOOAN model incorporates Sun's floating style construction, which minimizes internal binding risks caused by excessive installation torque or machining variations. This cartridge fits T21A cavities and belongs to Series 1, offering a capacity of up to 7 gpm (28 L/min). Its factory pressure settings are established at a flow rate of 4 gpm (15 L/min), with a maximum operating pressure reaching up to 5000 psi (350 bar). The valve exhibits low internal leakage, with maximum leakage rates at approximately 2 in\u00b3/min (30 cc/min) when operating at viscosities of around 110 SUS (24 cSt). The DRBOOAN model allows for adjustment through clockwise turns to increase settings, requiring specific torques for installation and locknut adjustments. Moreover, this valve is not bistable but can modulate between two positions as outlined in its specifications. It weighs .55 lb (.25 kg) and comes equipped with 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.
