The Sun Hydraulics DSCXXCN (DSCXXCN) is a vent-to-shift, 2-position diverter valve that is normally closed. This valve operates by shifting when port 1 is vented, and the pressure differential between port 3 and port 1 exceeds the spring force, thereby connecting port 3 with ports 2 and 4. It is not bistable but capable of modulating between its two positions. The vent flow out of port 1 is pressure compensated, requiring a pressure source at port 3 relative to port 1 for shifting. One application includes bypassing divider-combiner valves in limited-slip tractive circuits, allowing for efficient high-speed operation by creating a large path around these valves when open. Multiple diverter valves can be vented using one pilot valve if blocking checks are employed at port 1; otherwise, interaction may occur between high and low-pressure circuit legs. The vent-to-shift function is self-cleaning and contamination-resistant. Its hardened spool and sleeve ensure consistent low spool leakage rates and excellent wear characteristics. The Sun floating style construction minimizes internal part binding due to excessive torque or machining variations during installation. It fits into a T-31A cavity, belongs to Series 1 with a capacity of up to 15 gpm (60 L/min), and can withstand a maximum operating pressure of 5000 psi (350 bar). The nominal vent flow rate stands at 23 in\u00b3/min (0.38 L/min). The valve's hex size measures at .78 inches (22.2 mm), requiring an installation torque of between 30 - 35 lbf ft (41 - 47 Nm). It weighs .35 lb (.15 kg) and uses a Viton seal kit with the cartridge part number: 990031006.
