The Sun Hydraulics DMDASNV (DMDASNV) 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 unique soft shift capability which moderates the shock typically associated with valve actuation. Although it enhances system smoothness, this soft shift mechanism is not recommended for applications requiring critical timing or ramping control; for such needs, Sun's electroproportional valves are more suitable. The DMDASNV model is engineered to provide a slower response time compared to standard solenoid valves from Sun Hydraulics, with typical response times ranging between 150 ms to 300 ms depending on various factors such as flow rate, pressure, coil voltage, oil viscosity, and ambient temperature. To ensure optimal performance of the soft shift feature, it is advised that port 1 maintains positive pressure. This model also includes a push-type manual override control and boasts a fatigue rating for up to 5000 psi (350 bar) service in its solenoid tube assembly. It is essential to note that cartridges configured with EPDM seals should only be used with phosphate ester fluids as exposure to petroleum-based substances can damage these seals. Additionally, the valve utilizes a wet armature design where the working fluid surrounds the armature which may affect fluid integrity under prolonged energization. For further customization and environmental protection in challenging conditions, various coil connector options rated up to IP69K are available along with additional weatherized coils and kits. The DMDASNV also incorporates Sun's floating style construction which minimizes internal parts binding due to installation torque or cavity/cartridge machining variations. This model\u2019s design ensures high efficiency and reliable valve shifting due to its unique magnetic structure of the solenoid.

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.
