The Sun Hydraulics DSGYXDN (DSGYXDN) is a vent-to-shift diverter valve designed as a 2-position, 3-way cartridge that is normally open from port 3 to port 4. When port 1 is vented, and the pressure differential between port 3 and port 1 exceeds the spring force, the valve shifts to connect port 3 to port 2. This valve is not bistable and can modulate between the two positions. It features pressure-compensated vent flow out of port 1, requiring a pressure source at port 3 relative to port 1 for shifting. A common application includes using it in pairs for selecting between two motors or pumps. A single pilot valve can vent multiple diverter valves if blocking checks are used at each diverter's port 1; otherwise, interaction will occur between high and low-pressure circuit legs. The self-cleaning vent-to-shift function makes it insensitive to contamination, while the hardened spool and sleeve ensure low spool leakage rates and excellent wear characteristics. The valve incorporates Sun's floating style construction to reduce internal parts binding due to excessive installation torque or cavity/cartridge machining variations. It fits into a T-33A cavity, belongs to series 3, and has a capacity of up to 60 gpm (240 L/min) with a maximum operating pressure of 5000 psi (350 bar). The nominal vent flow rate is approximately 35 in\u00b3/min (0.60 L/min). The valve's hex size measures at 1\u00bc inches (31.8 mm), with an installation torque requirement between 150-160 lbf\u00b7ft (203-217 Nm). It weighs about 1.40 lb (0.65 kg) and uses Viton seal kit number: 990033006 for maintenance purposes.
