The Sun Hydraulics DMDASPV299 (DMDASPV299) is a solenoid-operated 3-way, 2-position cartridge valve designed for precise hydraulic fluid direction control. This direct-acting, balanced spool directional valve features a soft shift option that moderates the shock typically associated with valve actuation. Although it enhances system smoothness, it is not suitable for applications requiring critical timing or ramping control, which are better served by electroproportional valves. The soft shift model exhibits a slower response time compared to standard solenoids, ranging from 150 ms to 300 ms, dependent on various operational conditions such as flow rate, pressure, coil voltage, oil viscosity, and ambient temperature. This model includes a push-type manual override and is incompatible with other manual override options when configured with soft shift control; however, these can be installed in the field if necessary. It's important to note that manual overrides are not compatible with weatherized coils. The construction of the DMDASPV299 utilizes a wet armature design where the working fluid surrounds the armature \u2013 an aspect that needs consideration regarding fluid type and operational duration as heat can affect fluid integrity over time. The valve is fatigue rated for high-pressure applications up to 5000 psi (350 bar) and incorporates Sun\u2019s floating style construction to minimize internal binding due to installation variances. It supports a maximum flow capacity of 5 gpm (20 L/min) and features robust environmental sealing options up to IP69K for coils, ensuring reliability in diverse operating environments. Seal options include EPDM for phosphate ester fluids; however, exposure to petroleum-based fluids should be avoided as it damages the seals. This model's efficient magnetic design ensures high performance with optimal energy use, making it an effective solution for advanced hydraulic systems requiring reliable directional control and smooth operation.

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.
