The Sun Hydraulics DRBOLDV (Material Number: DRBOLDV) is a direct-acting, 3-way directional cartridge valve designed for moderate flow circuits. This versatile component operates by switching between two positions when the pressure differential between port 1 and port 4 exceeds a pre-set level. Port 3 can be utilized as a work port, with bidirectional flow paths available between ports 2 and 3, as well as ports 1 and 2. The valve's direct-acting design ensures low internal leakage and minimal pilot flow consumption, making it efficient for various applications. Additionally, this model is interchangeable with pilot-operated variants, sharing identical cavities and flow paths. The DRBOLDV is built to handle a maximum operating pressure of 5000 psi (350 bar) with a capacity of up to 7 gpm (28 L/min). It features Sun's floating style construction to reduce the risk of internal part binding due to excessive installation torque or machining variations. The valve's factory pressure settings are established at 4 gpm (15 L/min), and the maximum valve leakage at 110 SUS (24 cSt) is limited to 2 in\u00b3/min (30 cc/min). The adjustment mechanism allows for fine-tuning by turning clockwise up to five times to increase the setting. The installation process requires specific torque values: the valve hex size is .78 inches (22.2 mm) with an installation torque of 30-35 lbf ft (41-47 Nm), while the locknut requires a torque of 80-90 lbf in (9-10 Nm). A Viton seal kit is available under part number 990021006. This cartridge valve is suitable for applications where precise modulation between two positions is needed without bistable operation.

Direct-acting, 3-way directional cartridges (1 blocked, 2 to 3 open) 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.
- Port 3 can be used as a work port.
- 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.
- Direct-acting and pilot-operated versions of these valves are interchangeable. They fit the same cavities and have the same flow paths.
- Pressure at port 4 is directly additive to the setting of the valve.
- This valve is not bistable; it is capable of modulating between the two positions shown.
- The flow path between port 1 and port 2 is bidirectional.
- Maximum pressure at port 3 should be limited to 3000 psi (210 bar). This is due to fatigue strength limits not hydraulic operating limits.
- 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.
