The Sun Hydraulics DRBOLEN (DRBOLEN) is a direct-acting, 3-way directional cartridge valve designed for moderate flow circuits. It features a configuration where port 1 is blocked and ports 2 to 3 are open, making it suitable for switching applications. This valve can operate independently or be used to actuate larger pilot-operated directional cartridges or logic cartridges. The valve shifts based on the pressure differential between port 1 and port 4, which must exceed the set threshold for operation. Port 3 serves as a work port with bidirectional flow capability between ports 2 and 3, ensuring flexibility in application. Due to its direct-acting design, the DRBOLEN valve exhibits low internal leakage and minimal pilot flow consumption. It shares cavity compatibility with pilot-operated versions, allowing interchangeable use without altering flow paths. The valve accommodates a maximum operating pressure of up to 5000 psi (350 bar) while maintaining a maximum valve leakage of only 2 in\u00b3/min (30 cc/min) at standard fluid conditions (110 SUS/24 cSt). The floating style construction minimizes risks of internal binding due to excessive installation torque or machining variations. Installation specifications include a T21A cavity with a series capacity of 7 gpm (28 L/min) and factory pressure settings established at 4 gpm (15 L/min). The valve's adjustment can be modified by turning clockwise up to five times to increase setting, with specific torque requirements for installation and locknut adjustments provided. Overall, the Sun Hydraulics DRBOLEN offers robust performance with its ability to modulate between two positions without being bistable, making it an excellent choice for applications requiring precise control over moderate flow circuits.

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.
