The Sun Hydraulics DSCXXDN (DSCXXDN) is a vent-to-shift, 2-position diverter valve designed to be normally closed. This valve operates by venting port 1, which causes the pressure differential between port 3 and port 1 to exceed the spring force, thereby shifting the valve and connecting port 3 with ports 2 and 4. It is not bistable and can modulate between its two positions. The vent flow out of port 1 is pressure compensated, ensuring reliable performance under varying conditions. A pressure source at port 3 relative to port 1 is required for the valve to shift effectively. One notable application of this diverter valve is in bypassing divider-combiner valves within a limited-slip tractive circuit. When closed, oil flows through these divider-combiner valves, but when open, it provides a larger path around them for efficient high-speed operation. Multiple diverter valves can be vented using one pilot valve if blocking checks are installed at each diverter's port 1; otherwise, interaction between high and low-pressure legs may occur. The DSCXXDN features a self-cleaning vent-to-shift function that enhances its resistance to contamination. Its hardened spool and sleeve ensure consistent low spool leakage rates and excellent wear characteristics over time. Additionally, the floating style construction minimizes potential binding of internal parts due to excessive installation torque or machining variations in the cavity or cartridge. This model fits into cavity T-31A with a series rating of 1 and has a capacity of up to 15 gpm (60 L/min). It can operate at a maximum pressure of 5000 psi (350 bar) with a nominal vent flow rate of 23 in\u00b3/min (0.38 L/min). The valve's hex size measures .78 inches (22.2 mm), requiring an installation torque ranging from 30-35 lbf ft (41-47 Nm). The model weighs approximately .35 lb (.15 kg) and uses Viton seal kits for maintenance.
