The Sun Hydraulics DMDASNN612 (DMDASNN612) is a solenoid-operated 3-way, 2-position cartridge valve characterized by its direct-acting, balanced spool directional control mechanism. This model is specifically designed to facilitate soft shift operations, which significantly minimize hydraulic shock during valve actuation. Notably, this soft shift variant should not be used in applications requiring precise timing control, such as those needing exact ramping or timing due to its increased response time compared to standard solenoids. The typical response time for this model ranges between 150 ms and 300 ms, varying based on factors like flow rate, pressure, coil voltage, oil viscosity, and ambient temperature. The valve is equipped with a push-type manual override control and boasts a robust solenoid tube assembly rated for fatigue at 5000 psi (350 bar). It's important to ensure that port 1 maintains positive pressure for optimal performance of the soft shift feature. For applications involving phosphate ester fluids, cartridges configured with EPDM seals are recommended; however, these are susceptible to damage from petroleum-based substances. Additionally, the DMDASNN612 utilizes a wet armature design where the working fluid surrounds the armature which may affect fluid integrity under prolonged energization. Its magnetic design enhances efficiency by generating higher spool actuating force per watt expended. The model also incorporates Sun's floating style construction to reduce internal parts binding risks caused by excessive installation torque or cavity/cartridge machining discrepancies. This valve supports a maximum flow capacity of 5 gpm (20 L/min) and can handle pressures up to 5000 psi (350 bar). Manual override features require a force of about 5 lbs at 1000 psi at port 1. The unit itself weighs approximately 0.60 lb (0.30 kg) and has various coil connector options that provide environmental protection ratings 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.
