The Sun Hydraulics DRBRCEN (DRBRCEN) is a direct-acting, 3-way directional cartridge valve designed for moderate flow circuits. It features a configuration where ports 3 to 4 are open and port 2 is blocked, making it suitable for applications requiring precise control of hydraulic flow. This valve can operate independently or be used to actuate larger pilot-operated directional or logic cartridges. The shifting occurs when the pressure differential between port 1 and port 4 surpasses the set threshold, with a maximum setting of 800 psi (55 bar). Port 3's maximum pressure should not exceed 3000 psi (210 bar) due to fatigue strength limitations. The bidirectional flow path between ports 2 and 3 ensures versatile application capabilities. The DRBRCEN valve boasts low internal leakage and minimal pilot flow consumption due to its direct-acting design. It is capable of modulating between two positions but is not bistable. The floating style construction helps prevent internal parts from binding due to excessive installation torque or machining variations in the cavity/cartridge interface. This valve fits into the T21A cavity and belongs to series 1, with a capacity of handling up to 7 gpm (28 L/min). It can withstand a maximum operating pressure of up to 5000 psi (350 bar), with leakage limited to approximately 2 in\u00b3/min (30 cc/min) at standard viscosity levels. Adjustments can be made via clockwise turns, with a hex size of 7/8 inches (22.2 mm) for the valve and an installation torque range of 30-35 lbf\u00b7ft (41-47 Nm). A locknut hex size of 9/16 inches (15 mm) requires a torque setting between 80-90 lbf\u00b7in (9-10 Nm). For maintenance, Viton seal kits are available under part number: 990021006.

Direct-acting, 3-way directional cartridges (3 to 4 open, 2 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 4 exceeds the setting.
- Note: 800 psi (55 bar) is the highest setting possible with this valve.
- Maximum pressure at port 3 should be limited to 3000 psi (210 bar). This is due to fatigue strength limits not hydraulic operating limits.
- 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.
- 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.
