The Sun Hydraulics DNCADLN211 (DNCADLN211) is a high-performance, solenoid-operated, 4-way, 2-position cartridge valve that offers precise control in hydraulic systems. This direct-acting, balanced spool directional valve ensures a closed transition between positions, minimizing oil loss during shifting which is crucial in maintaining efficiency, especially in pilot control circuits. It is designed with port 3 as the inlet and port 1 as the tank outlet; however, while reverse flow is possible through the valve, optimal performance in this mode isn't guaranteed. The DNCADLN211 operates without requiring a minimum hydraulic pressure and features an innovative wet armature design. The armature being surrounded by working fluid helps manage heat from the coil but demands consideration of fluid type to avoid breakdown and varnish formation which could impair operation. Notably, cartridges with EPDM seals are specifically for use with phosphate ester fluids and must avoid contact with petroleum-based products. Engineered for robust performance, this valve has a solenoid tube assembly that is fatigue rated for up to 5000 psi (350 bar). It supports a flow capacity of up to 8 gpm (30 L/min) and can handle maximum operating pressures of 5000 psi (350 bar). The response time is quick at approximately 50 ms, and it allows for high switching frequencies up to 15,000 cycles per hour. For ease of use and installation flexibility, coils on this model are interchangeable with other Sun Series 1 solenoid products and can be mounted in either direction on the tube. Additionally, the DNCADLN211 incorporates Sun's floating style construction which reduces risks associated with internal parts binding due to excessive installation torque or variations in cavity/cartridge machining. With various coil termination options available along with voltage choices including surge protection options and environmental protection kits, this valve adapts well to diverse operational requirements and environments.
