The Sun Hydraulics DCECXTN (DCECXTN) is a versatile hydraulic valve ideal for advanced fluid power applications. This three-position, 4-way directional cartridge is spring-centered and features a 6-port configuration that allows it to function effectively under high-pressure conditions up to 5000 psi (350 bar). The valve's design incorporates a variety of spool options, enabling customization according to specific operational requirements and ensuring optimal performance in different scenarios. Each port, including the pilot ports (port 5 and port 6), can withstand the maximum operating pressure, making the DCECXTN suitable for high-demand applications. The capacity of these pilot-to-shift valves varies based on the selected spool type, primarily due to flow forces which are proportional to flow and pressure drop. These forces typically resist opening, and spools that open passages as they spring center are most affected. If flow forces exceed the centering spring force under certain conditions, the valve may not shift completely, indicating that higher flows might be possible at lower pressures. The DCECXTN also features hardened spool and sleeve components which provide low leakage rates and superior wear characteristics. It incorporates Sun's floating style construction which minimizes internal parts binding caused by excessive installation torque or cavity/cartridge machining variations. This design enhancement enhances durability and reliability in various hydraulic systems. For fluid compatibility, cartridges configured with EPDM seals are specifically designed for use with phosphate ester fluids; exposure to petroleum-based fluids can damage these seals. Key specifications include a flow capacity range of 25-100 gpm (95-380 L/min), minimum pilot pressure required for valve shifting at 125 psi (9 bar), and maximum leakage at 110 SUS (24 cSt) maintained at 2 in\u00b3/min per 1000 psi (30 cc/min per 70 bar). The model's robust construction is complemented by an installation torque requirement of 150-160 lbf\u00b7ft (203-217 Nm) and a modest weight of approximately 1.80 lbs (0.80 kg), ensuring easy handling and integration into various setups.
