The Sun Hydraulics DRCOKBN (DRCOKBN) is a direct-acting, 3-way directional cartridge valve designed for moderate flow circuits. This versatile component functions as a switching device with one port blocked and ports 2 to 3 open, making it suitable for standalone use or for actuating larger pilot-operated or logic cartridges. The valve operates by shifting when the pressure differential between port 1 and port 4 surpasses the preset threshold, with port 3 serving as a potential work port. Notably, the direct-acting design ensures low internal leakage and minimal pilot flow consumption. These valves are interchangeable with their pilot-operated counterparts, fitting identical cavities and sharing similar flow paths. The DRCOKBN model features Sun's floating style construction to reduce the risk of internal part binding due to excessive installation torque or cavity machining variations. It supports a maximum operating pressure of 5000 psi (350 bar) and accommodates up to 15 gpm (60 L/min) capacity. The valve's maximum leakage at 110 SUS (24 cSt) is limited to 2 in\u00b3/min (30 cc/min), and it allows for pressure adjustments through clockwise turns, enhancing its adaptability in various applications. Installation requires a torque between 45-50 lbf ft (61-68 Nm), with specific hex sizes designated for the valve body, adjustment screw, and locknut. The DRCOKBN model weighs approximately .55 lb (.25 kg) and includes a Viton seal kit option under part number 990022006. This valve is not bistable but can modulate between two positions based on operational needs, maintaining performance integrity within its specified pressure limits.

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.
