The Sun Hydraulics DRBNCDV (DRBNCDV) is a normally closed, direct-acting, 2-way directional cartridge valve designed for moderate flow circuits. This versatile component can function independently or as an actuator for larger pilot-operated directional or logic cartridges. The valve operates by shifting when the pressure differential between port 1 and port 4 surpasses a specific setting. It features a bidirectional flow path between port 2 and port 3, with port 3 also usable as a work port. Thanks to its direct-acting design, the DRBNCDV offers low internal leakage and minimal pilot flow consumption, making it efficient and reliable. Direct-acting and pilot-operated versions of these valves are interchangeable, sharing the same cavities and flow paths. The DRBNCDV is not bistable but can modulate between two positions based on pressure changes, with pressure at port 4 directly affecting the valve's setting. While the maximum operating pressure is rated at 5000 psi (350 bar), the maximum allowable pressure at port 3 is limited to 3000 psi (210 bar) due to fatigue strength considerations. The valve incorporates Sun's floating style construction to reduce risks of internal parts binding from excessive installation torque or machining variations in cavity-cartridge interfaces. Key specifications include a capacity of 7 gpm (28 L/min), factory pressure settings established at 4 gpm (15 L/min), and a maximum valve leakage of 2 in\u00b3/min (30 cc/min) at 110 SUS (24 cSt). The adjustment mechanism allows for setting increases through clockwise turns up to a specified limit. This model requires specific installation torques and includes Viton seal kits for ensuring optimal performance in hydraulic applications.

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.
