The Sun Hydraulics DRBRKSV (Material Number: DRBRKSV) is a direct-acting, 3-way directional cartridge valve designed for moderate flow circuits. This valve is capable of modulating between two positions, with port 3 to 4 open and port 2 blocked, making it ideal for applications that require switching devices. It operates effectively either as a standalone unit or in conjunction with larger pilot-operated directional cartridges or logic cartridges. The valve shifts when the pressure differential between port 1 and port 4 exceeds its setting, which can be adjusted up to a maximum of 800 psi (55 bar). This cartridge features a maximum operating pressure of 5000 psi (350 bar) and can handle a capacity of up to 7 gpm (28 L/min). The flow path between ports 2 and 3 is bidirectional, allowing for versatile application within hydraulic systems. Its design minimizes internal leakage and pilot flow consumption while incorporating Sun's floating style construction to reduce the risk of internal parts binding due to excessive installation torque or machining variations. The DRBRKSV model requires an installation torque of 30-35 lbf ft (41-47 Nm) with a locknut torque specification of 80-90 lbf in (9-10 Nm). The valve's hex size measures at 7/8 inch (22.2 mm), while the locknut hex size is specified at 9/16 inch (15 mm). For maintenance purposes, it utilizes Viton seal kits available under part number 990021006. This valve is not bistable; however, its robust construction ensures stability and reliability in various hydraulic applications where precise modulation is necessary.

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.
