The Sun Hydraulics DRBRKEV (DRBRKEV) is a direct-acting, 3-way directional cartridge valve designed for moderate flow circuits. This versatile component can be used independently or to actuate larger pilot-operated directional or logic cartridges. The valve operates by shifting when the pressure differential between port 1 and port 4 surpasses the set threshold, with a maximum setting of 800 psi (55 bar). Its design ensures low internal leakage and minimal pilot flow consumption. Notably, the valve features a bidirectional flow path between port 2 and port 3 and is not bistable, meaning it can modulate between the two positions shown. Constructed with Sun's floating style to reduce internal part binding due to installation torque or machining variations, this valve is robust and reliable. It fits into cavity T21A and belongs to Series 1 with a capacity of 7 gpm (28 L/min). The maximum operating pressure is rated at 5000 psi (350 bar), while pressure at port 3 should be limited to 3000 psi (210 bar) due to fatigue strength limits. The valve has a hex size of 7/8 inches (22.2 mm) for installation torque ranging from 30 to 35 lbf ft (41 to 47 Nm), while the locknut hex size is 9/16 inches (15 mm) with a torque range of 80 to 90 lbf in (9 to 10 Nm). For maintenance, Viton seal kits are available under part number 990021006. This cartridge valve's design makes it suitable for applications requiring fast response times and dirt tolerance in hydraulic systems.

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.
