The Sun Hydraulics DSCHXEV (DSCHXEV) 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 component is engineered to spring-center into an all-ports-blocked position when both work ports, 2 and 4, are at equal pressures. When one work port experiences higher pressure, it connects the opposite work port to the common port, 3. The innovative hydraulic stop feature eliminates mechanical impact, reducing internal damage risks and allowing for the hot oil relief setting to be confirmed with the transmission in neutral. This valve fits into a 4-port cavity but does not utilize the nose port 1. Incorporating Sun's floating style construction, this cartridge minimizes internal binding issues due to excessive installation torque or machining variations. The DSCHXEV fits a T-31A cavity and belongs to Series 1 with a capacity of up to 10 gpm (40 L/min). It can withstand a maximum operating pressure of 5000 psi (350 bar) while maintaining a pilot flow rate of 23 in\u00b3/min (0.38 L/min). The valve has a hex size of 7/8 inch (22.2 mm) and requires an installation torque between 30 - 35 lbf ft (41 - 47 Nm). Weighing .40 lb (.20 kg), it is compatible with Viton seal kits under part number 990031006. This direct-acting valve is suitable for applications requiring rapid response times and robustness against dirt, making it ideal for preventing overpressure scenarios in various hydraulic systems.

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.
