The Sun Hydraulics DMDASNV72499 (DMDASNV72499) is a high-performance, solenoid-operated 3-way, 2-position cartridge valve designed for precise hydraulic flow control. This direct-acting, balanced spool directional valve is equipped with a soft shift feature to mitigate shock from valve actuation, although it is not suitable for applications requiring critical timing control. The soft shift design increases the response time of the valve, typically ranging from 150 ms to 300 ms, influenced by factors such as flow rate, pressure, coil voltage, oil viscosity, and ambient temperature. This model showcases a push-type manual override control and incorporates Sun's floating style construction that minimizes internal part binding due to installation torque or cavity/cartridge machining variations. Notably, the solenoid tube assembly of this valve is fatigue rated for up to 5000 psi (350 bar). It is essential to use cartridges with EPDM seals specifically in systems using phosphate ester fluids as exposure to petroleum-based substances can damage these seals. The DMDASNV72499 operates optimally when port 1 maintains positive pressure and features a wet armature design where the working fluid surrounds the armature. This aspect should be considered if the coil remains energized for extended periods since some fluids may degrade under prolonged heat exposure. With a maximum operating capacity of 5 gpm (20 L/min) and pressure up to 5000 psi (350 bar), this valve ensures robust performance in various hydraulic applications. Its manual override requires minimal force (5 lbs at 1000 psi at Port 1), and it has an override stroke of .10 inches (2.5 mm). The solenoid's magnetic design enhances efficiency by maximizing spool actuating force per watt expended. For environmental protection options and additional specifications on coil connectors rated up to IP69K are available upon reviewing individual product pages related to this model.

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.
