The Sun Hydraulics DMDASPV298 (DMDASPV298) is a solenoid-operated 3-way, 2-position cartridge valve that offers a direct-acting, balanced spool directional control. This model is designed with a soft shift feature that reduces shock from valve actuation, making it suitable for applications sensitive to sudden changes in pressure but not ideal where precise timing control is crucial. The valve's response time varies between 150 ms to 300 ms depending on several factors including flow, pressure, coil voltage, oil viscosity, and ambient temperature. For optimal performance of the soft shift feature, it is recommended that port 1 maintains positive pressure. This unit includes a push-type manual override control and features a solenoid tube assembly rated for up to 5000 psi (350 bar), ensuring robust performance under high-pressure conditions. The DMDASPV298 utilizes EPDM seals which are compatible with phosphate ester fluids but can be damaged by exposure to petroleum-based substances. Additionally, its wet armature design means the working fluid surrounds the armature which could affect fluid integrity over extended periods of energization. The valve also boasts a high-efficiency solenoid design that maximizes spool actuating force per watt expended for reliable shifting. It supports various coil connector options with ratings up to IP69K for enhanced environmental protection. Notably, it incorporates Sun's floating style construction which minimizes internal parts binding due to installation torque or machining variations of the cavity/cartridge. With a flow capacity of 5 gpm (20 L/min) and maximum operating pressure of 5000 psi (350 bar), along with minimal leakage and manual override capabilities, the Sun Hydraulics DMDASPV298 is engineered for effective performance in demanding hydraulic systems requiring directional control and shock mitigation.

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.
