The Sun Hydraulics DSEHXEN (Material Number: DSEHXEN) is a lowside hot oil shuttle cartridge designed for closed loop systems. It efficiently diverts hot oil from the low-pressure side of the system. The valve operates with a unique mechanism that centers to an all-ports-blocked position when work ports 2 and 4 are at equal pressures. If one port experiences higher pressure, the opposite port connects to the common port, port 3. The spool features a hydraulic stop, preventing mechanical impact and internal damage, allowing for a small pilot flow from high-pressure work ports to the common port. An advantage of this hydraulic stop is that it permits confirmation of the hot oil relief setting with the transmission in neutral. However, caution should be exercised when selecting shift pressure due to potential low shift values causing inadvertent valve shifts by charge pump pressure alone. The valve fits into a T32A cavity and is part of Series 2, offering a capacity of 20 gpm (80 L/min) and handling a maximum operating pressure of 5000 psi (350 bar). It maintains pilot flow at 23 in\u00b3/min (0.38 L/min). The design incorporates Sun's floating style construction, minimizing internal part binding from excessive installation torque or machining variations. With a hex size of 1-1/8 inches (28.6 mm) and installation torque between 45-50 lbf ft (61-68 Nm), it weighs approximately .70 lb (0.30 kg). The cartridge also supports Viton seal kits under part number 990032006 for reliable sealing performance in various applications.

Low-side (hot oil) shuttle cartridges allow hot oil to be diverted from the low pressure side of a closed loop system. 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 the opposite work port is connected to the common port (port 3).
- The spool incorporates a hydraulic stop that eliminates mechanical impact and therefore the potential for internal damage.
- The hydraulic stop results in a small pilot flow from the high side work port (port 2 or 4) to the common port (port 3).
- A unique feature due to the hydraulic stop is that the hot oil relief setting can be confirmed with the transmission in neutral.
- NOTE: Low shift values can potentially result in charge pump pressure alone inadvertently shifting the valve. Use care when selecting shift pressure.
- 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.
