The Sun Hydraulics DRBRLSV (DRBRLSV) is a direct-acting, 3-way directional cartridge valve designed for moderate flow circuits. It is suitable for applications where switching between port 3 to 4 open and port 2 blocked configurations is required. This valve can function independently or be used to actuate larger pilot-operated directional cartridges 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). Port 3 has a maximum pressure limit of 3000 psi (210 bar) due to fatigue strength considerations, although the hydraulic operating limit is higher. The flow path between ports 2 and 3 is bidirectional, ensuring versatility in circuit design. The DRBRLSV features low internal leakage and minimal pilot flow consumption due to its direct-acting design, making it efficient in various applications. It is not bistable but can modulate between two positions as needed. The valve incorporates Sun's floating style construction, which reduces the risk of internal parts binding from excessive installation torque or machining variations in the cavity or cartridge. With a capacity of 7 gpm (28 L/min) and a maximum operating pressure of 5000 psi (350 bar), this valve offers reliable performance under demanding conditions. It has a valve hex size of 7/8 inch (22.2 mm) and requires an installation torque of 30-35 lbf ft (41-47 Nm). The locknut hex size is 9/16 inch (15 mm), with a torque requirement of 80-90 lbf in (9-10 Nm). A Viton seal kit is available for maintenance purposes, ensuring long-term durability and leak-free operation.

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.
