The Sun Hydraulics DSCYXDN (DSCYXDN) is a vent-to-shift diverter valve designed as a 2-position, 3-way cartridge that is typically open from port 3 to port 4. When port 1 is vented and the pressure differential between port 3 and port 1 surpasses the spring force, the valve shifts to connect port 3 to port 2. This valve is not bistable and can modulate between its two positions. It requires a pressure source at port 3 relative to port 1 for shifting. One of its applications includes using it in pairs to select between two motors or pumps. A single pilot valve can vent multiple diverter valves if blocking checks are utilized at each diverter's port 1; otherwise, there will be interaction between high and low-pressure legs of the circuit. The vent-to-shift function is self-cleaning, making it resistant to contamination. The hardened spool and sleeve ensure consistent low spool leakage rates and excellent wear characteristics, while the Sun floating style construction minimizes internal parts binding due to excessive installation torque or machining variations in cavity/cartridge configurations. This model fits into a T-31A cavity, belongs to series 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 approximately .23 in\u00b3/min (.38 L/min). The valve features a hex size of .78 inches (22.2 mm) and requires an installation torque ranging from 30-35 lbf ft (41-47 Nm). Weighing .35 lb (.15 kg), this valve comes with Viton seal kits available under part number 990031006.
