The Sun Hydraulics DRBRKEN (Material Number DRBRKEN) is a direct-acting, 3-way directional cartridge valve designed for moderate flow circuits. This valve is typically utilized as a switching device and can function independently or in conjunction with larger pilot-operated or logic cartridges. It operates by shifting when the pressure differential between port 1 and port 4 surpasses the set threshold, with an upper limit of 800 psi (55 bar). The valve features a bidirectional flow path between port 2 and port 3, while the maximum pressure at port 3 should not exceed 3000 psi (210 bar) due to fatigue strength constraints. This model incorporates Sun's floating style construction, reducing the risk of internal part binding from excessive installation torque or cavity machining variations. The DRBRKEN can modulate between two positions but is not bistable. It has a capacity of 7 gallons per minute (28 liters per minute) and can withstand a maximum operating pressure of 5000 psi (350 bar). The valve's design ensures low internal leakage and minimal pilot flow consumption, making it efficient for various applications. The hex size for installation is 7/8 inch (22.2 mm), requiring a torque of 30 to 35 lbf ft (41 to 47 Nm). Additionally, it includes a locknut with a hex size of 9/16 inch (15 mm), which needs to be torqued to 80 to 90 lbf in (9 to 10 Nm). For maintenance purposes, Viton seal kits are available under part number 990021006. This robust cartridge valve is suitable for applications where rapid response and dirt tolerance are essential, providing stable performance across diverse 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.
