The Sun Hydraulics DSIYXEN (DSIYXEN) is a specialized vent-to-shift diverter valve designed as a 2-position, 3-way cartridge that is normally open from port 3 to port 4. When port 1 is vented, the pressure differential between port 3 and port 1 exceeds the spring force, causing the valve to shift and connect port 3 to port 2. This valve is not bistable but can modulate between its two positions. It features pressure-compensated vent flow out of port 1, ensuring reliable operation as detailed in its technical data. A key application includes using the valve in pairs for selecting between two motors or pumps. It allows for a single pilot valve to vent multiple diverter valves when blocking checks are used at each diverter's port 1; without these checks, interaction occurs between high and low-pressure circuit legs. The self-cleaning vent-to-shift function makes it insensitive to contamination. Constructed with hardened spool and sleeve, it offers consistent low spool leakage rates and excellent wear characteristics. The floating style construction minimizes internal parts binding due to excessive installation torque or machining variations in cavity/cartridge assembly. With a capacity of up to 120 gpm (480 L/min) and a maximum operating pressure of 5000 psi (350 bar), this model fits into a T-34A cavity and requires an installation torque of 350 - 375 lbf ft (475 - 508 Nm). Weighing in at approximately 3.30 lb (1.50 kg), the DSIYXEN ensures robust performance with its Viton seal kit option available under part number 990034006, making it suitable for demanding hydraulic applications where reliability and precise control are paramount.
