The Sun Hydraulics DRBRLNV (DRBRLNV) is a direct-acting, 3-way directional cartridge valve designed for use in moderate flow circuits. It is capable of switching between two positions, specifically 3 to 4 open and 2 blocked, and can be used independently or to actuate larger pilot-operated directional or logic cartridges. The valve shifts when the pressure differential between port 1 and port 4 exceeds the set threshold, with a maximum setting of 800 psi (55 bar). The valve's construction allows for a maximum operating pressure of 5000 psi (350 bar) at port 3, although fatigue strength limits suggest keeping this below 3000 psi (210 bar). Additionally, the flow path between ports 2 and 3 is bidirectional. This cartridge features low internal leakage and pilot flow consumption due to its direct-acting design. It incorporates Sun's floating style construction to reduce the risk of internal parts binding from excessive installation torque or machining variations. With a capacity of up to 7 gpm (28 L/min), it provides reliable performance in various hydraulic applications. The valve includes adjustment capabilities with up to five clockwise turns to increase the setting and requires specific torque settings for installation and locknut adjustments. A Viton seal kit is available for maintenance needs.

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.
