The Sun Hydraulics DSIHXEV (DSIHXEV) is a lowside hot oil shuttle cartridge designed for closed loop systems, allowing hot oil to be diverted from the low-pressure side. When both work ports 2 and 4 are at equal pressures, the valve remains spring-centered in an all-ports-blocked position. If one work port experiences higher pressure, the opposite port connects to the common port 3. This valve features a hydraulic stop that prevents mechanical impact and potential internal damage, resulting in a small pilot flow from the high side work port to the common port. Notably, this design allows for confirmation of the hot oil relief setting with the transmission in neutral. It is important to carefully select shift pressure due to potential low shift values causing inadvertent valve shifts by charge pump pressure alone. The valve fits into a 4-port cavity but does not use nose port 1. Its floating style construction minimizes binding risks due to excessive installation torque or machining variations. With a capacity of 80 gpm (320 L/min), it operates under a maximum pressure of 5000 psi (350 bar). The pilot flow rate is approximately 46 in\u00b3/min (0.75 L/min), and it requires an installation torque between 350 and 375 lbf ft (475 - 508 Nm). The unit weighs approximately 2.90 lb (1.30 kg) and uses Viton seal kits for cartridges, specifically model number 990034006.

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.
