The Sun Hydraulics DMDASNV624N (DMDASNV624N) is a solenoid-operated 3-way, 2-position cartridge valve which functions as a direct-acting, balanced spool directional valve. This model is designed with a soft shift feature to minimize hydraulic shock during valve actuation, although it is not suitable for applications requiring precise timing control, for which electro-proportional valves are recommended. The soft shift model has a slower response time compared to standard solenoid valves from Sun Hydraulics, typically ranging from 150 ms to 300 ms, varying with flow, pressure, coil voltage, oil viscosity, and ambient temperature. The valve\u2019s performance and soft shifting are optimized when port 1 maintains positive pressure. It includes a push-type manual override control; however, other manual control options are not compatible with the soft shift feature but can be installed in the field if necessary. The solenoid tube assembly of the valve is rated for fatigue at 5000 psi (350 bar). It also features EPDM seals suitable for systems using phosphate ester fluids but vulnerable to damage from petroleum-based fluids. Moreover, the DMDASNV624N uses a wet armature design where the working fluid surrounds the armature which could lead to fluid degradation under prolonged energization. Its magnetic design enhances efficiency by maximizing spool actuating force per watt expended. Various coil connector options provide up to IP69K protection with additional weatherized coils available for enhanced environmental resilience. This model also incorporates Sun\u2019s floating style construction to reduce internal parts binding caused by excessive installation torque or cavity/cartridge machining variations. With its comprehensive design focused on durability and performance adaptability in diverse operational conditions, this valve ensures reliable hydraulic directional control in various applications.

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.
