The Sun Hydraulics DRCOLSN (Material Number: DRCOLSN) is a direct-acting, 3-way directional cartridge valve designed for moderate flow circuits. This versatile valve can be used independently or to actuate larger pilot-operated directional or logic cartridges. It operates by shifting when the pressure differential between port 1 and port 4 exceeds the set value, with port 3 serving as a work port. Notably, this valve features low internal leakage and minimal pilot flow consumption due to its direct-acting design. The DRCOLSN valve is not bistable and is capable of modulating between its two positions. It incorporates Sun's floating style construction to reduce the risk of internal component binding caused by excessive installation torque or machining variations in the cavity/cartridge. The valve fits into a T-22A cavity and belongs to Series 2, offering a capacity of up to 15 gpm (60 L/min). Factory pressure settings are established at 4 gpm (15 L/min), with a maximum operating pressure of 5000 psi (350 bar). The maximum allowable pressure at port 3 should not exceed 3000 psi (210 bar) due to fatigue strength limits. The valve's hex size is 1-1/8 inches (28.6 mm), and it requires an installation torque of 45\u201350 lbf ft (61\u201368 Nm). Adjustments are made via an internal hex screw, with clockwise turns increasing the setting across a range of up to five full turns. The locknut hex size is 9/16 inches (15 mm), requiring a torque of 80\u201390 lbf in (9\u201310 Nm) for secure fastening. The model weighs approximately .55 lb (.25 kg) and uses Viton seal kits for reliable performance in various 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.
