The Sun Hydraulics DSCLXFN (DSCLXFN) is a lowside hot oil shuttle cartridge designed to divert hot oil from the low-pressure side of a closed-loop system. It operates by connecting the work port with lower pressure to the common port when there is a pressure differential between work ports 2 and 4; otherwise, it remains spring-centered in an all-ports-blocked position. This model does not utilize the nose port 1, making it suitable for specific applications where this configuration is needed. With a capacity of 15 gpm (60 L/min) and a maximum operating pressure of 5000 psi (350 bar), this valve is robust enough for demanding hydraulic systems. The valve incorporates Sun's floating style construction, which helps prevent internal parts from binding due to excessive installation torque or machining variations. It fits into a T-31A cavity and weighs approximately 0.40 lbs (0.20 kg). Installation requires a torque of 30-35 lbf ft (41-47 Nm), and it has a hex size of 7/8 in. (22.2 mm). Maximum valve leakage at 110 SUS (24 cSt) is limited to 1 in\u00b3/min at 1000 psi (15 cc/min at 70 bar). The DSCLXFN model does not include a hydraulic stop or pilot flow, which may be unsuitable for some circuits outside hydrostatic transmissions due to potential leakage concerns. Additionally, users should exercise caution when selecting shift pressures as low shift values might inadvertently cause the valve to shift solely under charge pump pressure.

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).
- 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.
- This valve does not have a hydraulic stop and therefore has no pilot flow. Some circuits other than hydrostatic transmissions cannot tolerate the added leakage.
- 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.
