The Sun Hydraulics DSIYXDN (DSIYXDN) is a vent-to-shift diverter valve designed as a 2-position, 3-way cartridge that operates normally open from port 3 to port 4. This valve shifts to connect port 3 to port 2 when the pressure differential between port 3 and port 1 surpasses the spring force upon venting at port 1. It is not bistable and can modulate between its two positions, making it versatile for various applications. 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 necessary for shifting the valve. Commonly used in pairs, this valve can select between two motors or pumps. When utilizing one pilot valve to vent multiple diverter valves, blocking checks should be employed at each diverter's port 1 to prevent interaction between high and low-pressure circuit legs. Its self-cleaning vent-to-shift function makes it insensitive to contamination, enhancing reliability in demanding environments. The hardened spool and sleeve ensure consistent, low spool leakage rates and excellent wear characteristics over time. Sun's floating style construction minimizes the risk of internal parts binding due to excessive installation torque or machining variations in the cavity/cartridge interface. With a capacity of up to 120 gpm (480 L/min) and a maximum operating pressure of 5000 psi (350 bar), this cartridge fits into a T-34A cavity with a nominal vent flow of 35 in\u00b3/min (0.60 L/min). The valve features a hex size of 1-5/8 inches (41.3 mm) and requires an installation torque ranging from 350 to 375 lbf ft (475 to 508 Nm). Weighing approximately 3.30 lb (1.50 kg), it utilizes Viton seal kits for optimal performance under various conditions.
