The Sun Hydraulics DRBNCAV (DRBNCAV) is a normally closed, direct-acting, 2-way directional cartridge valve designed for moderate flow circuits. This versatile component can function independently or be used 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 a predetermined setting, with port 3 available as a work port. It allows bidirectional flow between ports 2 and 3, providing flexibility in various applications. Thanks to its direct-acting design, the DRBNCAV offers low internal leakage and minimal pilot flow consumption, making it an efficient choice for hydraulic systems. The valve is interchangeable with pilot-operated versions, fitting the same cavities and maintaining consistent flow paths. The pressure at port 4 directly adds to the valve's setting, allowing precise control over its operation. Notably, this valve is not bistable; it can modulate between two positions based on system demands. The DRBNCAV incorporates Sun's floating style construction to minimize potential binding of internal parts due to excessive installation torque or machining variations in cavities or cartridges. Its maximum operating pressure reaches up to 5000 psi (350 bar), with a capacity of handling flows up to 7 gpm (28 L/min). Factory pressure settings are established at a flow rate of 4 gpm (15 L/min). Maximum allowable leakage at 110 SUS (24 cSt) is limited to 2 in\u00b3/min (30 cc/min). Installation specifics include a hex size of 7/8 inch (22.2 mm) and installation torque ranging from 30 to 35 lbf-ft (41 to 47 Nm). The adjustment screw features an internal hex size of 5/32 inch (4 mm), while the locknut requires a torque range of 80 to 90 lbf-in (9 to 10 Nm).

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.
