The Sun Hydraulics DMDASPN724 (DMDASPN724) is a high-performance solenoid-operated 3-way, 2-position cartridge valve designed for precise control in hydraulic systems. This direct-acting, balanced spool directional valve features a unique soft shift capability that moderates the shock typically associated with valve actuation, making it suitable for applications sensitive to sudden changes in pressure or flow. However, it is noted that this soft shift feature may not be suitable for operations requiring critical timing or exact ramping controls. The valve is engineered with a wet armature design where the working fluid surrounds the armature, which can affect fluid integrity under prolonged energization. It also incorporates Sun's floating style construction to reduce internal parts binding due to installation torque or machining variations of cavity/cartridge. The manual override feature included in this model provides additional operational flexibility, although it is incompatible with weatherized coils. This model boasts a maximum operating pressure of 5000 psi (350 bar) and a flow capacity of up to 5 gpm (20 L/min), ensuring robust performance even under strenuous conditions. The solenoid tube assembly of the DMDASPN724 is fatigue rated for high-pressure service, enhancing its durability and lifespan. Additionally, this valve offers various coil connector options with ratings up to IP69K for enhanced environmental protection. The DMDASPN724 is ideal for use in hydraulic systems requiring reliable and smooth directional control with the option for manual override when necessary, provided that consistent positive pressure at port 1 is maintained. Its specialized design features make it an effective solution for managing hydraulic flow with reduced system shocks and increased operational stability.

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.
