The Sun Hydraulics DRBRCEV (DRBRCEV) is a direct-acting, 3-way directional cartridge valve designed for moderate flow circuits. This model features a configuration where ports 3 to 4 are open and port 2 is blocked, making it versatile for various applications. It can be utilized independently or to actuate larger pilot-operated directional or logic cartridges. The valve operates by shifting when the pressure differential between port 1 and port 4 exceeds the preset limit, with an upper setting threshold of 800 psi (55 bar). It is crucial to note that the maximum pressure at port 3 should not exceed 3000 psi (210 bar) due to fatigue strength limitations. The flow path between ports 2 and 3 is bidirectional, allowing for flexible integration into hydraulic systems. This cartridge valve boasts low internal leakage and minimal pilot flow consumption due to its direct-acting design. It is not bistable but capable of modulating 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 cavity/cartridge design. With a capacity of up to 7 gpm (28 L/min) and a maximum operating pressure of 5000 psi (350 bar), this valve ensures robust performance in demanding environments. Installation requires specific torque settings: a valve hex size of 7/8 in. (22.2 mm), installation torque of 30\u201335 lbf ft (41\u201347 Nm), and locknut hex size of 9/16 in. (15 mm) with locknut torque at 80\u201390 lbf in. (9\u201310 Nm). Additionally, the Viton seal kit for this cartridge is identified by part number 990021006, ensuring compatibility and reliability in sealing performance.

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.
