The Sun Hydraulics DSEHXDN (Material Number: DSEHXDN) is a lowside hot oil shuttle cartridge designed to efficiently divert hot oil from the low-pressure side of a closed-loop hydraulic system. This valve is engineered to spring-center to an all-ports-blocked position when both work ports, ports 2 and 4, are at equal pressures. If one work port experiences higher pressure, the opposite port connects to the common port, port 3. A key feature of this product is its hydraulic stop, which eliminates mechanical impact and potential internal damage. This design results in a small pilot flow from the high-pressure work port to the common port, allowing for hot oil relief setting confirmation with the transmission in neutral. It's important to note that low shift values could cause charge pump pressure alone to inadvertently shift the valve; hence, careful selection of shift pressure is advised. The DSEHXDN incorporates Sun's floating style construction, reducing the risk of internal components binding due to excessive installation torque or cavity/cartridge machining variations. The valve fits into a T32A cavity and belongs to Series 2 with a capacity of 20 gpm (80 L/min) and can handle a maximum operating pressure of 5000 psi (350 bar). It features a pilot flow rate of 23 in\u00b3/min (0.38 L/min), with a valve hex size of 1-1/8 in (28.6 mm) and installation torque between 45-50 lbf ft (61-68 Nm). The model weighs approximately .70 lb (0.30 kg) and uses Viton seal kits for optimal performance.

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.
