The Sun Hydraulics DRCOLBN (DRCOLBN) is a direct-acting, 3-way directional cartridge valve designed for moderate flow circuits. This valve features one blocked port and an open path between ports 2 and 3, making it suitable for applications where switching devices are needed. It can function independently or be used to actuate larger pilot-operated or logic cartridges. The valve activates when the pressure differential between port 1 and port 4 surpasses the set threshold, with port 3 serving as a work port. Its direct-acting design ensures low internal leakage and minimal pilot flow consumption, and it can be interchanged with pilot-operated versions due to shared cavity dimensions and flow paths. The DRCOLBN model utilizes Sun's floating style construction, which helps prevent internal part binding from excessive installation torque or machining variations in the cavity/cartridge. The maximum operating pressure is rated at 5000 psi (350 bar), while the maximum allowable pressure at port 3 is limited to 3000 psi (210 bar) due to fatigue strength considerations. With a capacity of 15 gpm (60 L/min), factory pressure settings are established at a flow rate of 4 gpm (15 L/min). The valve's hex size is 1-1/8 inches (28.6 mm), requiring an installation torque of between 45 - 50 lbf-ft (61 - 68 Nm). Adjustment involves up to five full clockwise turns to increase settings, using an internal hex size of 5/32 inches (4 mm) for the adjustment screw. This model weighs approximately .55 lbs (.25 kg) and comes with a Viton seal kit option under part number 990022006. The DRCOLBN offers robust performance with its ability to modulate between two positions rather than being bistable, making it a reliable choice for various hydraulic circuit applications.

Direct-acting, 3-way directional cartridges (1 blocked, 2 to 3 open) 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 4 exceeds the setting.
- Port 3 can be used as a work port.
- 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.
- Pressure at port 4 is directly additive to the setting of the valve.
- This valve is not bistable; it is capable of modulating between the two positions shown.
- Maximum pressure at port 3 should be limited to 3000 psi (210 bar). This is due to fatigue strength limits not hydraulic operating limits.
- 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.
