The Sun Hydraulics DNDYSXN724 (DNDYSXN724) is a solenoid-operated, 6-way, 2-position cartridge valve designed with a direct-acting, balanced spool and a soft shift feature to minimize system shock during valve actuation. This valve is typically used to alternate between two separate circuits: in its de-energized state, it connects P and T to the first circuit, and when energized, it shifts to connect P and T to the second circuit. While the soft shift feature reduces shock, it should not be relied upon for applications requiring precise timing; for such needs, electroproportional valves are recommended. The soft shift results in increased response time compared to standard solenoids, ranging from 150 ms to 300 ms depending on factors like flow rate, pressure, coil voltage, oil viscosity, and ambient temperature. This cartridge valve is interchangeable with standard cartridges but has lower performance limits. It features a push-type manual override control for ease of operation; however, this function is incompatible with weatherized coils. The solenoid tube assembly is rated for fatigue at 5000 psi (350 bar), ensuring durability under high pressure. Designed with a wet armature configuration, the solenoid delivers high efficiency by generating substantial spool actuating force per watt expended. The DNDYSXN724 incorporates Sun's floating style construction to reduce internal binding risks due to installation torque or cavity machining variations. It fits into cavity T-61A and belongs to Series 1 with a capacity of 5 gpm (20 L/min). The valve's maximum operating pressure is 5000 psi (350 bar), with a leakage rate of up to 5 in\u00b3/min at 3000 psi (80 cc/min at 210 bar). The unit weighs approximately .60 lb (.30 kg) and requires an installation torque of 30 - 35 lbf ft (41 - 47 Nm).

This solenoid-operated 6-way, 2-position cartridge is a direct-acting, balanced spool valve with a soft shift feature. The soft shift feature greatly reduces system shock due to valve actuation. The typical use for this valve is to select between two separate circuits. The de-energized condition connects P and T to the first circuit and when energized connects P and T to the second circuit.
- The soft shift cartridge is interchangeable with the standard cartridge, however, the performance limits are lower.
- The soft shift feature can greatly reduce shock due to valve actuation but should not be counted upon in applications where timing is critical. If you need accurate ramping or timing control, consider Sun's electro-proportional valves.
- The soft shift feature results in significant increase in response time over Sun's standard solenoid. Response time is dependant on flow, pressure, coil voltage, oil viscosity and ambient temperature. Typical response time ranges from 150 ms to 300 ms.
- For consistent soft shift performance, port 1 should be at a positive pressure.
- This valve includes a push-type manual override control. Other manual control options such as T or D, cannot be ordered with the soft shift control but can be installed easily in the field. See Twist/Lock Manual Override link above for details. Please note: Manual override functionality is not compatible with weatherized coils.
- The solenoid tube assembly is fatigue rated for 5000 psi (350 bar) service.
- This valve is direct actuated and requires no minimum hydraulic pressure for operation.
- This valve utilizes a wet armature design. This means that the working fluid surrounds the armature and is exposed to the heat generated by the coil. This can be a factor if the coil is energized for long periods of time. Some fluids, notably water/glycol mixtures, break down at these temperatures over time and form varnishes that will affect the function of the cartridge.
- The solenoid's unique magnetic design results in a high efficiency solenoid, yielding high spool actuating force per Watt expended, leading to reliable valve shifting.
- Coils are interchangeable with other Sun Series 1 solenoid products and can be mounted on the tube in either direction.
- Coil connector options offer ratings up to IP69K. See individual coil product pages for details. Additional weatherized coils and kits are available for more complete environmental protection.
- Incorporates the Sun floating style construction to minimize the possibility of internal parts binding due to excessive installation torque and/or cavity/cartridge machining variations.
