The Sun Hydraulics DRCOLAV (DRCOLAV) is a direct-acting, 3-way directional cartridge valve that functions as a switching device in moderate flow circuits. This versatile component can be used independently or to actuate larger pilot-operated directional or logic cartridges. Its design allows for low internal leakage and minimal pilot flow consumption, making it highly efficient. The valve operates by shifting when the pressure differential between port 1 and port 4 surpasses the set threshold, with port 3 serving as a work port. Notably, the pressure at port 4 directly adds to the valve's setting. The DRCOLAV is capable of modulating between two positions and is not bistable. The maximum pressure at port 3 should be limited to 3000 psi (210 bar) due to fatigue strength constraints rather than hydraulic operating limits. The valve incorporates Sun's floating style construction to reduce the risk of internal parts binding from excessive installation torque or machining variations in cavity/cartridge setups. It fits a T-22A cavity and belongs to Series 2 with a capacity of 15 gpm (60 L/min). Factory pressure settings are established at 4 gpm (15 L/min), and it can handle a maximum operating pressure of up to 5000 psi (350 bar). Leakage is minimal, with a maximum valve leakage of just 2 in\u00b3/min (30 cc/min) at 110 SUS (24 cSt). The adjustment mechanism allows for increased settings through clockwise turns, with detailed specifications on hex sizes and installation torques provided for precise application. The model weighs .55 lb (.25 kg), and Viton seal kits are available for maintenance needs.

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.
