The Sun Hydraulics DSCLXEV (DSCLXEV) is a lowside hot oil shuttle cartridge designed to divert hot oil from the low-pressure side of a closed-loop hydraulic system. This component is engineered to handle a maximum operating pressure of 5000 psi (350 bar) and has a flow capacity of 15 gpm (60 L/min). The valve is constructed with Sun's floating style design, which minimizes the risk of internal parts binding due to excessive installation torque or variations in cavity/cartridge machining. It features a T-31A cavity and requires an installation torque between 30 and 35 lbf-ft (41 to 47 Nm). The valve's hex size measures at 7/8 inch (22.2 mm), and it weighs approximately .40 lb (.20 kg). When both work ports, ports 2 and 4, are at equal pressures, the DSCLXEV centers itself to an all-ports-blocked position. If one work port experiences higher pressure, the opposite port connects to the common port, port 3. Notably, this valve does not utilize nose port 1 and lacks a hydraulic stop, meaning it has no pilot flow\u2014a factor that should be considered for circuits that cannot tolerate additional leakage. Users should exercise caution when selecting shift pressure due to potential low shift values that might inadvertently cause the valve to shift with charge pump pressure alone. The DSCLXEV is ideal for applications requiring reliable control over oil diversion in hydraulic systems while maintaining minimal leakage rates\u20141 in\u00b3/min at 1000 psi (15 cc/min at 70 bar). A Viton seal kit is available under part number 990031006 for maintenance needs.
