The Sun Hydraulics DRBDOWN (Material Number: DRBDOWN) is a direct-acting, 3-way directional cartridge valve designed for moderate flow circuits. It operates by shifting when the pressure differential between port 1 and port 3 exceeds a pre-set value. The valve's design ensures low internal leakage and minimal pilot flow consumption, making it efficient for use in various hydraulic applications. It can be utilized independently or to actuate larger pilot-operated directional cartridges or logic cartridges. This model features Sun's floating style construction, reducing the risk of internal components binding due to excessive installation torque or machining variations. The valve has a capacity of 7 gpm (28 L/min) and can handle a maximum operating pressure of 5000 psi (350 bar). It fits into cavity T-11A and is interchangeable with other direct-acting and pilot-operated versions due to its consistent cavity fit and flow paths. While it is capable of modulating between two positions, it's not bistable, meaning it won't maintain a stable position without input. The adjustment mechanism allows for precise control with up to 5.5 clockwise turns needed to increase the pressure setting. The valve's hex size is 7/8 inch (22.2 mm), requiring an installation torque between 30 to 35 lbf ft (41 to 47 Nm). Its locknut requires a torque of 80 to 90 lbf in (9 to 10 Nm) for secure adjustments, using an internal hex size of 5/32 inch (4 mm). The DRBDOWN model weighs approximately .60 lb (0.30 kg) and uses Viton seals for optimal performance in demanding environments.

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.
