The Sun Hydraulics DRCOLDN (Material Number: DRCOLDN) is a direct-acting, 3-way directional cartridge valve designed for moderate flow circuits. This valve is typically used to switch between two flow paths, with port 1 blocked and ports 2 to 3 open. It can operate independently or be used to actuate larger pilot-operated directional or logic cartridges. The valve shifts when the pressure differential between port 1 and port 4 surpasses a pre-set threshold, allowing it to modulate between positions rather than being bistable. Port 3 serves as a work port, with a maximum pressure limit of 3000 psi (210 bar) due to fatigue strength constraints. The direct-acting design ensures low internal leakage and minimal pilot flow consumption, making it efficient in various applications. The DRCOLDN features Sun's floating style construction, which minimizes the risk of internal parts binding due to excessive installation torque or machining variations. It fits the T-22A cavity and belongs to Series 2, with a capacity of handling up to 15 gpm (60 L/min). The factory pressure settings are established at a flow rate of 4 gpm (15 L/min), with a maximum operating pressure of up to 5000 psi (350 bar). The valve allows for adjustment through clockwise turns, with detailed specifications on hex sizes and torque requirements provided for installation and maintenance. Additionally, the model has a weight of .55 lb (0.25 kg) and includes Viton seal kits for enhanced durability in hydraulic systems.

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.
