The Sun Hydraulics DCFCXNV (DCFCXNV) is a versatile three-position, 4-way directional cartridge valve, designed for high-pressure hydraulic systems. This model is spring-centered and features a 6-port configuration with a supply port at port 3. Each port on the DCFCXNV can withstand up to 5000 psi or 350 bar, including the x and y pilot ports (port 5 and port 6). The valve's performance varies with different spool types due to flow forces, which are proportional to flow and pressure drop. These forces typically resist the opening of a passage, especially in spool configurations that open passages as they spring center. The DCFCXNV is capable of handling flows ranging from 50 to 200 gallons per minute (200 to 760 liters per minute). It requires a minimum pilot pressure of 125 psi (9 bar) to shift the valve and can operate at a maximum pressure of 5000 psi (350 bar). The model incorporates Sun\u2019s floating style construction which minimizes internal parts binding caused by excessive installation torque or cavity/cartridge machining variations. This design feature, along with hardened spool and sleeve, ensures low spool leakage rates and excellent wear characteristics. To ensure compatibility with various hydraulic fluids, cartridges configured with EPDM seals are specifically designed for systems using phosphate ester fluids; these seals should not be exposed to petroleum-based fluids. Leakage specifications are detailed for each path within the technical data provided by Sun Hydraulics. The DCFCXNV also comes equipped with positively sealed pilot ports from the work ports, ensuring reliable operation and maintenance ease in demanding environments.
