The Sun Hydraulics DMDASNV612N (DMDASNV612N) is a high-performance solenoid-operated 3-way, 2-position cartridge valve featuring direct-acting, balanced spool directional control with a unique soft shift capability. This model is designed to mitigate shock during valve actuation, making it suitable for applications where reducing system shock is critical; however, it should not be relied upon for critical timing applications. For such needs, Sun Hydraulics recommends considering their electro-proportional valves instead. The DMDASNV612N valve boasts a response time between 150 ms to 300 ms, influenced by various factors including flow, pressure, coil voltage, oil viscosity, and ambient temperature. It integrates a push-type manual override control and has an option for other manual controls to be installed in the field if the soft shift feature is not required. The valve's solenoid tube assembly is fatigue rated for service up to 5000 psi (350 bar), ensuring robust performance under high-pressure conditions. This model utilizes EPDM seals specifically for use with phosphate ester fluids; exposure to petroleum-based fluids can damage these seals. Additionally, its wet armature design means that the working fluid surrounds the armature which can be subjected to heat if the coil remains energized over extended periods. This aspect should be considered as certain fluids may degrade under sustained high temperatures. Equipped with Sun's floating style construction, the DMDASNV612N minimizes internal parts binding and accommodates machining variations or excessive installation torque effectively. Its coil connector options are rated up to IP69K for enhanced environmental protection against ingress of dust and water during high-pressure wash-downs. This model supports a flow capacity of up to 5 gpm (20 L/min) and can handle maximum operating pressures up to 5000 psi (350 bar), making it versatile across various hydraulic applications while maintaining minimal leakage and efficient 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.
