The Sun Hydraulics DSEYXDN (DSEYXDN) is a 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 surpasses the spring force, causing the valve to shift and connect port 3 to port 2. This valve is not bistable and can modulate between these two positions. The vent flow out of port 1 is pressure compensated, requiring a pressure source at port 3 relative to port 1 for shifting. It can be used in pairs for selecting between two motors or pumps and allows one pilot valve to vent multiple diverter valves if blocking checks are installed at each diverter\u2019s port 1. Without blocking checks, there will be interaction between high and low-pressure legs of the circuit. The self-cleaning vent-to-shift function makes it insensitive to contamination, while the hardened spool and sleeve ensure consistent low spool leakage rates and excellent wear characteristics. The Sun floating style construction minimizes internal part binding due to excessive installation torque or cavity/cartridge machining variations. It fits into a T-32A cavity, belongs to series 2, has a capacity of up to 30 gpm (120 L/min), and can handle a maximum operating pressure of up to 5000 psi (350 bar). The nominal vent flow is rated at .23 in\u00b3/min (.38 L/min). Installation requires a torque of between 45-50 lbf ft (61-68 Nm), with the model weighing .70 lb (.30 kg). Viton seal kits are available under part number 990032006 for maintenance purposes.
