The Sun Hydraulics DRBOKEV (Material Number: DRBOKEV) is a direct-acting, 3-way directional cartridge valve designed for use in moderate flow circuits. This valve functions as a switching device with one blocked port and an open flow path between ports 2 and 3, which is bidirectional. It can be utilized 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 pressure at port 4 being directly additive to the setting of the valve. Notably, this valve is not bistable and can modulate between two positions. The DRBOKEV features low internal leakage and low pilot flow consumption due to its direct-acting design, making it efficient for specific applications. It incorporates Sun's floating style construction to minimize binding risks from excessive installation torque or machining variations. The valve fits T21A cavities, belongs to Series 1, and has a capacity of 7 gpm (28 L/min). Factory pressure settings are established at a flow rate of 4 gpm (15 L/min), with a maximum operating pressure of 5000 psi (350 bar). The maximum allowable pressure at port 3 is limited to 3000 psi (210 bar) due to fatigue strength limits rather than hydraulic operating limits. Adjustments can be made using an internal hex screw with a size of 5/32 inch (4 mm). The model weighs .55 lb (0.25 kg) and utilizes Viton seal kits for optimal performance. With its robust design, this cartridge valve provides reliable modulation capabilities across various hydraulic applications.

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.
