The Sun Hydraulics DRBDLBV (DRBDLBV) is a direct-acting, 3-way directional cartridge valve designed for moderate flow circuits. This valve configuration allows for port 1 to 2 to remain open while port 3 is blocked, making it suitable for use either independently or to actuate larger pilot-operated or logic cartridges. The valve operates by shifting when the pressure differential between port 1 and port 3 surpasses the preset threshold. Notably, pressure at port 3 directly influences the valve's setting, potentially limiting its use as a work port in certain circuits; however, a 4-port version of this valve is available to address such scenarios. The DRBDLBV features low internal leakage and minimal pilot flow consumption due to its direct-acting design. It is interchangeable with pilot-operated versions in terms of cavity fit and flow paths but differs in operation as it is not bistable and can modulate between positions. The Sun floating style construction minimizes risks of internal binding caused by excessive installation torque or machining variations. Key specifications include compatibility with cavity T-11A, a series designation of 1, and a capacity of handling up to 7 gpm (28 L/min). It operates at a maximum pressure of 5000 psi (350 bar) with factory pressure settings established at 4 gpm (15 L/min). The maximum valve leakage rate is specified at 2 in\u00b3/min (30 cc/min) under conditions of fluid viscosity at 110 SUS (24 cSt). Installation requires a torque range of 30 - 35 lbf ft (41 - 47 Nm), and adjustments are made via an internal hex screw with specific dimensions provided for hex sizes. The model weighs .60 lb (.30 kg) and utilizes Viton seals as part of its construction.

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.
