The Sun Hydraulics DRBBLEN (Material Number: DRBBLEN) is a normally closed, direct-acting, 2-way directional cartridge valve designed for moderate flow circuits. It can function independently or trigger larger pilot-operated directional or logic cartridges. The valve operates by shifting when the pressure differential between port 1 and port 3 surpasses the set threshold, with pressure at port 3 being directly additive to this setting. Due to this characteristic, port 3 may not serve as a work port in certain circuits; a 4-port version of the valve may be more suitable in such cases. These direct-acting cartridges are known for their low internal leakage and minimal pilot flow consumption. They are interchangeable with pilot-operated versions, sharing cavity compatibility and flow paths. Notably, this valve is not bistable but can modulate between two positions as needed. The design incorporates Sun's floating style construction, minimizing potential binding from excessive installation torque or machining variations. Key specifications include a T-11A cavity, series 1 classification, and a capacity of 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 110 SUS (24 cSt). The adjustment mechanism allows for increasing settings through clockwise turns up to five times. Installation 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). The model weighs approximately .60 lb (.30 kg) and uses a Viton seal kit identified as 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.
