The Sun Hydraulics DRBNCEV (DRBNCEV) is a normally closed, direct-acting, 2-way directional cartridge valve designed for moderate flow circuits. It can be used independently or to actuate larger pilot-operated directional cartridges or logic cartridges. The valve operates by shifting when the pressure differential between port 1 and port 4 exceeds the preset threshold. Port 3 can function as a work port, with bidirectional flow possible between ports 2 and 3. Its direct-acting design ensures low internal leakage and minimal pilot flow consumption. This valve is interchangeable with pilot-operated versions, fitting the same cavities and maintaining identical flow paths. The DRBNCEV incorporates Sun's floating style construction to reduce the risk of internal parts binding due to excessive installation torque or machining variations. With a maximum operating pressure of 5000 psi (350 bar) and a capacity of 7 gpm (28 L/min), it meets demanding hydraulic applications while maintaining reliability. The valve features a cavity size of T-21A, with factory pressure settings established at 4 gpm (15 L/min). It is not bistable but can modulate between two positions as needed. For installation, the valve requires a torque of 30-35 lbf ft (41-47 Nm), with an adjustment screw internal hex size of 5/32 in. (4 mm) and locknut hex size of 9/16 in. (15 mm). The locknut should be torqued to 80-90 lbf in. (9-10 Nm). Weighing .55 lb (.25 kg), this model includes Viton seal kits available for optimal performance.

Normally closed, direct-acting, 2-way directional cartridges 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.
- 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.
