The Sun Hydraulics DSCYXDV (DSCYXDV) is a vent-to-shift diverter valve designed as a 2-position, 3-way cartridge that typically remains open from port 3 to port 4. When port 1 is vented and the pressure differential between ports 3 and 1 surpasses the spring force, the valve shifts to connect port 3 to port 2. This valve is not bistable and can modulate between these two positions. It features pressure-compensated vent flow out of port 1, with technical data available for reference. A pressure source at port 3, relative to port 1, is necessary for shifting the valve. The DSCYXDV can be applied in pairs for selecting between two motors or pumps. A single pilot valve may vent multiple diverter valves if blocking checks are installed at each diverter's port 1; otherwise, interaction may occur between high and low-pressure circuit legs. The self-cleaning vent-to-shift function makes it resistant to contamination. Its hardened spool and sleeve ensure low spool leakage rates and excellent wear characteristics. Utilizing Sun's floating style construction minimizes potential binding of internal parts due to excessive installation torque or cavity/cartridge machining variations. The valve fits into a T-31A cavity with a series capacity of up to 15 gpm (60 L/min) and can withstand a maximum operating pressure of up to 5000 psi (350 bar). The nominal vent flow measures at approximately .23 in\u00b3/min (.38 L/min). The installation requires a torque setting between 30-35 lbf ft (41-47 Nm), and the model weighs .35 lb (.15 kg). For maintenance, Viton seal kit number 990031006 is available.
