The Sun Hydraulics DMDASNN72499 (DMDASNN72499) is a high-performance, solenoid-operated 3-way, 2-position cartridge valve designed for hydraulic systems requiring reliable directional control. This direct-acting, balanced spool 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 important to note that this soft shift feature may not be ideal for operations where precise timing control is critical. With a maximum operating pressure of 5000 psi (350 bar) and a flow capacity of up to 5 gpm (20 L/min), the DMDASNN72499 is well-suited for various medium to high-pressure applications. The valve's manual override function, integrated with a push-type control, adds an extra layer of operational flexibility, although it should be noted that alternate manual controls are not compatible with the soft shift feature but can be added later if needed. The construction of the DMDASNN72499 includes Sun Hydraulics\u2019 floating style design which minimizes internal parts binding and ensures consistent performance even under varying installation conditions. The solenoid tube assembly is fatigue rated for robustness in demanding environments. Additionally, the wet armature design indicates that the working fluid surrounds the armature which could affect fluid properties if exposed to heat over extended periods. This model incorporates EPDM seals specifically for use with phosphate ester fluids; exposure to petroleum-based fluids can damage these seals. For environments requiring enhanced protection against elements, weatherized coils and kits are available separately. Overall, the Sun Hydraulics DMDASNN72499 offers robust performance with added features like soft shifting and manual override, tailored for systems where shock reduction and flexibility are key operational parameters.

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.
