The Sun Hydraulics DSCSXEV (DSCSXEV) is a highside shuttle cartridge designed for use in full-time regeneration circuits. This valve is particularly effective for overrunning load control in applications where the load tends to extend the cylinder. It features a spool-sleeve construction that provides excellent wear characteristics and minimizes cross leakage, although it does not fully prevent drift due to spool leakage. The valve operates by connecting the higher pressure work port, either port 2 or 4, to the common port 3 when pressures are unequal, while spring-centering to an all-ports-blocked position when pressures are equal. Notably, it fits into a 4-port cavity but does not utilize the nose port 1. This cartridge incorporates Sun's floating style construction, which helps minimize internal parts binding from excessive installation torque or variations in cavity/cartridge machining. With a capacity of 15 gpm (60 L/min) and a maximum operating pressure of 5000 psi (350 bar), this valve is robust enough for demanding applications. The valve has minimal leakage at maximum conditions, with specifications indicating a leakage rate of 2 in\u00b3/min at 1000 psi (30 cc/min at 70 bar). Installation requires a torque between 30 and 35 lbf\u00b7ft (41 and 47 Nm), and it has a hex size of 7/8 inch (22.2 mm). Weighing just .40 lb (.20 kg), this model also comes with an available Viton seal kit under part number 990031006.

High-side shuttle cartridges are most often used in full-time regeneration circuits. When both work ports (ports 2 and 4) are at equal pressures the valve is spring-centered to an all-ports-blocked position. When one of the work ports (port 2 or 4) sees a higher pressure it is connected to the common port (port 3).
- This valve provides overrunning load control in regeneration applications where the load tends to extend the cylinder. Because there is spool leakage, it does not prevent drift.
- Hardened spool/sleeve construction provides excellent wear characteristics and minimizes cross leakage.
- Although this valve goes into a 4-port cavity, the nose (port 1) is not used.
- 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.
