The Sun Hydraulics DSESXFN (DSESXFN) is a highside shuttle cartridge valve designed primarily for full-time regeneration circuits. It is engineered to manage overrunning load control in applications where the load tends to extend the cylinder, making it ideal for certain hydraulic systems. The valve operates by connecting the common port (port 3) to the work port with higher pressure, while both work ports (ports 2 and 4) are at equal pressures, resulting in a spring-centered all-ports-blocked position. The hardened spool-sleeve construction ensures excellent wear characteristics and minimizes cross leakage, although it does not completely prevent drift due to spool leakage. This valve fits into a 4-port cavity but does not utilize the nose port (port 1). It incorporates Sun's floating style construction, which reduces the risk of internal parts binding due to excessive installation torque or cavity/cartridge machining variations. With a capacity of up to 30 gpm (120 L/min.) and a maximum operating pressure of 5000 psi (350 bar), this series 2 valve offers robust performance under demanding conditions. The maximum valve leakage at 110 SUS (24 cSt) is rated at 3 in\u00b3/min at 1000 psi (50 cc/min at 70 bar). Installation requires a torque of between 45 - 50 lbf ft (61 - 68 Nm), and it has a hex size of 1-1/8 inches (28.6 mm). The model weighs approximately .70 lb (.30 kg) and uses Viton seal kits, specifically part number: 990032006.

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.
