The Sun Hydraulics DRBBLDN (DRBBLDN) 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. It operates by shifting when the pressure differential between port 1 and port 3 surpasses the set threshold, with pressure at port 3 being additive to the setting. This feature necessitates consideration of port usage in circuit design, as port 3 may not be suitable as a work port. Alternatively, a 4-port version of this valve could address such concerns. The DRBBLDN valve boasts low internal leakage and minimal pilot flow consumption due to its direct-acting design. It is interchangeable with pilot-operated versions, sharing cavity compatibility and flow paths, though it is not bistable and can modulate between two positions. The Sun floating style construction minimizes risks of internal binding from excessive installation torque or machining variations. Key specifications include a T-11A cavity type, 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). The valve features minimal leakage at maximum viscosity levels and allows adjustment via an internal hex screw. With a model weight of .60 lb (.30 kg) and Viton seal kit compatibility (990011006), this valve is robust yet lightweight. Installation requires specific torque values for both the valve itself and its locknut to ensure optimal performance in hydraulic systems.

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.
