The Sun Hydraulics DRBRKSN (DRBRKSN) 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 switching devices. This valve can function independently or be utilized to actuate larger pilot-operated directional cartridges or logic cartridges. The DRBRKSN shifts when the pressure differential between port 1 and port 4 surpasses the preset threshold, with an upper limit of 800 psi (55 bar). The maximum pressure at port 3 should not exceed 3000 psi (210 bar) due to fatigue strength constraints. The valve's design allows for bidirectional flow between port 2 and port 3, offering flexibility in various hydraulic systems. Its direct-acting nature ensures low internal leakage and minimal pilot flow consumption, making it efficient in operation. Unlike bistable valves, the DRBRKSN can modulate between its two positions as required by system demands. It incorporates Sun's floating style construction to reduce the risk of internal binding from excessive installation torque or variations in cavity/cartridge machining. This cartridge fits into a T-21A cavity and belongs to Series 1 with a capacity of handling up to 7 gallons per minute (28 liters per minute). It operates under a maximum pressure of up to 5000 psi (350 bar), with a maximum valve leakage rate of just 2 cubic inches per minute (30 cc/min) at an oil viscosity of 110 SUS (24 cSt). Installation requires a torque setting between 30\u201335 lbf ft (41\u201347 Nm), while the locknut should be torqued between 80\u201390 lbf in (9\u201310 Nm). The seal kit for this cartridge is made from Viton material, ensuring durability and reliability in various applications.

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.
