The Sun Hydraulics DRBRCSN (DRBRCSN) is a direct-acting, 3-way directional cartridge valve designed for moderate flow circuits with a specific configuration where ports 3 to 4 are open and port 2 is blocked. This versatile valve can be used independently or to actuate larger pilot-operated directional cartridges or logic cartridges. The valve shifts when the pressure differential between port 1 and port 4 surpasses the set threshold, with a maximum allowable setting of 800 psi (55 bar). It is crucial to ensure that the pressure at port 3 does not exceed 3000 psi (210 bar) due to fatigue strength limitations. The flow path between ports 2 and 3 is bidirectional, enhancing its adaptability in various applications. The DRBRCSN features Sun's floating style construction, minimizing internal part binding risks due to excessive installation torque or machining variations. With a capacity of up to 7 gpm (28 L/min) and a maximum operating pressure of 5000 psi (350 bar), it offers robust performance in demanding environments. The valve exhibits low internal leakage and minimal pilot flow consumption, making it efficient for modulating between its two positions rather than being bistable. Designed for use in T-21A cavities, this Series 1 cartridge incorporates specific installation requirements such as a valve hex size of 7/8 inch (22.2 mm) and an installation torque range of 30 - 35 lbf ft (41 - 47 Nm). Additionally, the locknut hex size is specified at 9/16 inch (15 mm) with a torque range of 80 - 90 lbf in. Viton seal kits are available for maintenance purposes, ensuring longevity and reliable 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.
