The Sun Hydraulics DMDASNN223 (DMDASNN223) is a solenoid-operated 3-way, 2-position cartridge valve designed for hydraulic applications requiring directional control and soft shift functionality. This direct-acting, balanced spool valve is known for its ability to significantly reduce shock during valve actuation, which is beneficial in systems where hydraulic shock can cause damage or undesired system behavior. Although the soft shift feature increases the response time of the valve (typically ranging from 150 ms to 300 ms), it makes the valve less suitable for applications where precise timing control is critical. This model incorporates a push-type manual override and has a fatigue rating of up to 5000 psi (350 bar), making it robust for high-pressure applications. The manual override feature, however, is not compatible with weatherized coils, which should be considered when operating in harsh environments. The DMDASNN223 also features a wet armature design; hence, it requires careful selection of fluids to prevent breakdown and varnish formation that could impair performance. Designed with EPDM seals, the DMDASNN223 is specifically configured for use with phosphate ester fluids; exposure to petroleum-based fluids can damage these seals. The valve's construction includes Sun's floating style design which minimizes internal part binding due to installation torque or machining variations of the cavity/cartridge. In terms of physical specifications, this model supports a flow capacity up to 5 gpm (20 L/min) and can handle maximum operating pressures up to 5000 psi (350 bar). It has manual override requirements of 5 lbs at 1000 psi for port 1 and features a solenoid tube diameter of .75 inches (19 mm). The overall weight of the model is modest at .60 lb (0.30 kg), facilitating ease of installation with recommended torque settings between 30 - 35 lbf ft (41 -47 Nm). The DMDASNN223\u2019s capabilities make it an ideal choice for various hydraulic systems looking for reliable performance with enhanced control over shock impacts during operations.

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.
