The Sun Hydraulics DRBBLSN (DRBBLSN) is a normally closed, direct-acting, 2-way directional cartridge valve designed for moderate flow circuits. It is primarily used for switching applications and can either function independently or actuate larger pilot-operated directional cartridges or logic cartridges. The valve operates by shifting when the pressure differential between port 1 and port 3 surpasses the set threshold. Notably, the pressure at port 3 directly adds to the valve's setting, which may limit its use as a work port in certain circuits. If this poses an issue, a 4-port version of this valve could be considered as an alternative. The DRBBLSN features low internal leakage and minimal pilot flow consumption due to its direct-acting design. It is interchangeable with pilot-operated versions, fitting the same cavities and maintaining identical flow paths. This valve is not bistable; it can modulate between two positions as required. Additionally, it incorporates Sun's floating style construction to reduce the risk of internal component binding due to excessive installation torque or machining variations in cavity-cartridge interfaces. Key specifications include a T-11A cavity, Series 1 classification, a capacity of 7 gpm (28 L/min), and a maximum operating pressure of 5000 psi (350 bar). The factory pressure settings are established at 4 gpm (15 L/min), with maximum valve leakage at 110 SUS (24 cSt) being approximately 2 in\u00b3/min (30 cc/min). The adjustment requires up to five clockwise turns to increase settings, with specific torque requirements for installation and locknut adjustments. Seal kits are available in Viton: part number 990011006.

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 3 exceeds the setting.
- Pressure at port 3 is directly additive to the setting of the valve. Because of this, port 3 may not be useable as a work port in your circuit. If this is a consideration, the 4 port version of this valve may be a solution.
- 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.
- This valve is not bistable; it is capable of modulating between the two positions shown.
- 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.
