The Sun Hydraulics DRBDLSN/AP (DRBDLSN/AP) is a direct-acting, 3-way directional cartridge valve designed for moderate flow circuits. It allows for switching between ports 1 and 2 while blocking port 3, making it suitable for use alone or in conjunction with larger pilot-operated directional or logic cartridges. The valve shifts when the pressure differential between port 1 and port 3 exceeds a preset threshold. Notably, pressure at port 3 directly adds to the valve's setting, which might limit its usability as a work port in certain circuits; in such cases, a 4-port version may be considered. With its direct-acting design, the DRBDLSN/AP features low internal leakage and minimal pilot flow consumption, ensuring efficient operation. This design also allows interchangeability with pilot-operated versions due to identical cavity fittings and flow paths. The valve is not bistable; it can modulate between two positions as needed. Sun's floating style construction minimizes risks of internal parts binding from excessive installation torque or machining variations. Key specifications include a T-11A cavity size, series 1 classification, and a capacity of up to 7 gpm (28 L/min). Factory pressure settings are established at 4 gpm (15 L/min), with a maximum operating pressure of 5000 psi (350 bar). Maximum valve leakage is rated at 2 in\u00b3/min (30 cc/min) at an oil viscosity of 110 SUS (24 cSt). Adjustments can be made through clockwise turns to increase pressure settings, facilitated by an internal hex adjustment screw size of 5/32 inches (4 mm). The valve has a hex size of 7/8 inches (22.2 mm) and requires an installation torque between 30 and 35 lbf-ft (41 to 47 Nm). Additionally, it includes a locknut with dimensions of 9/16 inches (15 mm) that should be torqued to between 80 and 90 lbf-in (9 to 10 Nm). The model weighs approximately .60 lb (.30 kg) and uses Viton seal kits for cartridge sealing.

Direct-acting, 3-way directional cartridges (1 to 2 open, 3 blocked) 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.
