The Sun Hydraulics DMDASPN299 (DMDASPN299) is a high-performance solenoid-operated 3-way, 2-position cartridge valve designed for hydraulic applications requiring reliable directional control. This direct-acting, balanced spool valve offers a unique soft shift feature that moderates the shock typically associated with valve actuation, although it is not recommended for applications where precise timing control is critical. For such needs, Sun Hydraulics suggests considering their electro-proportional valves instead. The DMDASPN299 incorporates a wet armature design where the working fluid surrounds the armature, potentially affecting fluid integrity under prolonged energized conditions. Its magnetic design enhances efficiency, delivering strong spool actuating force per watt expended which ensures dependable valve shifting. The unit has a maximum operating pressure of 5000 psi (350 bar) and a flow capacity of 5 gpm (20 L/min), making it suitable for various high-pressure applications. This model features manual override capabilities with a push-type control and has options for other manual controls to be added in the field if the soft shift feature is not used. However, these are incompatible with weatherized coils. The solenoid tube assembly of this model is fatigue rated for robust performance under demanding conditions. Additional durability is provided by its IP69K-rated coil connector options and available weatherized coils and kits that offer enhanced environmental protection. The valve also employs Sun\u2019s floating style construction to minimize internal parts binding due to installation stresses or machining variations in the cavity/cartridge setup. Overall, the Sun Hydraulics DMDASPN299 offers a versatile solution for controlling directional flow in hydraulic systems, combining durability with enhanced operational smoothness thanks to its soft shift technology.

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.
