The Sun Hydraulics DMDASNN724N (DMDASNN724N) is a solenoid-operated 3-way, 2-position cartridge valve featuring direct-acting, balanced spool directional control with a unique soft shift feature. This design significantly increases response times (150 ms to 300 ms), compared to standard solenoids, which helps to minimize shock during valve actuation. Although the soft shift model is interchangeable with standard cartridges, its performance limits are lower and it is not suitable for applications requiring precise timing control. For optimal performance, this valve should be used where port 1 maintains positive pressure. It includes a push-type manual override which is not compatible with weatherized coils and offers alternative manual control options that can be field-installed. The unit is fatigue rated for up to 5000 psi (350 bar) service and incorporates EPDM seals specifically for use with phosphate ester fluids; exposure to petroleum-based fluids can damage these seals. The DMDASNN724N utilizes a wet armature design allowing the working fluid to surround the armature which may affect fluid integrity over prolonged periods due to heat exposure from the coil. Its high-efficiency magnetic design ensures reliable valve shifting by generating high spool actuating force per watt expended. Additional features include IP69K-rated coil connector options for enhanced environmental protection and Sun's floating style construction that prevents internal part binding due to installation or machining variations. This model accommodates up to 5 gpm (20 L/min) flow capacity and can withstand maximum operating pressures of up to 5000 psi (350 bar). It also features minimal leakage at high pressures, maintaining robust performance across various operational conditions.

This solenoid-operated 3-way, 2-position cartridge is a direct-acting, balanced spool directional valve.
- 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 dependent 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.
- Cartridges configured with EPDM seals are for use in systems with phosphate ester fluids. Exposure to petroleum based fluids, greases and lubricants will damage the seals.
- 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.
- 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.
