The Sun Hydraulics DSCHXGN (DSCHXGN) 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 operates by spring-centering to an all-ports-blocked position when work ports 2 and 4 are at equal pressures. When either port 2 or 4 experiences higher pressure, the opposite work port connects to the common port, port 3. The spool features a hydraulic stop, eliminating mechanical impact and reducing the risk of internal damage, while allowing a small pilot flow from the high-pressure side work port to the common port. A notable feature due to this hydraulic stop is that users can confirm the hot oil relief setting with the transmission in neutral. Care should be taken with low shift values as they may inadvertently shift the valve due to charge pump pressure alone. Although this valve fits into a 4-port cavity, it does not utilize nose port 1. The Sun floating style construction minimizes internal part binding risks caused by excessive installation torque or machining variations in cavity/cartridge manufacturing. Key specifications include a T-31A cavity, Series 1 classification, and a capacity of up to 10 gpm (40 L/min). It can handle a maximum operating pressure of 5000 psi (350 bar) and has a pilot flow rate of approximately 23 in\u00b3/min (0.38 L/min). The valve hex size measures at 7/8 inches (22.2 mm), with an installation torque range between 30 - 35 lbf ft (41 - 47 Nm). The model weighs approximately .40 lb (0.20 kg) and is compatible with Viton seal kits such as part number 990031006 for maintenance purposes.

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.
