The Sun Hydraulics DMDASNV612 (DMDASNV612) is a solenoid-operated 3-way, 2-position cartridge valve, featuring a direct-acting, balanced spool directional control. This model is specifically designed with a soft shift feature to mitigate shock from valve actuation, which is beneficial in applications sensitive to sudden movements or shocks, though it is not suitable for use 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. This model incorporates a push-type manual override and is engineered with a fatigue-rated solenoid tube assembly for up to 5000 psi (350 bar) service. It employs EPDM seals optimized for phosphate ester fluids; however, these seals are susceptible to damage when exposed to petroleum-based substances. The wet armature design of the solenoid means that the working fluid surrounds the armature which could be an issue during prolonged energization as heat buildup can degrade certain types of hydraulic fluids. The DMDASNV612 benefits from Sun's floating style construction which minimizes internal part binding due to installation torque or machining variations in the cavity/cartridge. It supports up to 5 gpm (20 L/min) capacity and can handle maximum operating pressures of 5000 psi (350 bar). The manual override requires a force of about 5 lbs per 1000 psi at port 1. The valve\u2019s robust magnetic design ensures efficient solenoid operation and reliable spool actuating force per watt expended. For enhanced environmental protection, additional weatherized coils and kits are available with coil connector options rated up to IP69K.

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.
