The Sun Hydraulics DMDASRN224N (DMDASRN224N) is a solenoid-operated 3-way, 2-position cartridge valve that features a direct-acting, balanced spool design. This model is specifically designed to offer a soft shift option, which helps in reducing the shock typically associated with valve actuation. Although this feature increases the response time of the valve (typically ranging from 150 ms to 300 ms), it makes the valve less suitable for applications requiring precise timing control. For such needs, Sun Hydraulics suggests considering their electro-proportional valves instead. The DMDASRN224N includes a push-type manual override and has an operational pressure capacity of up to 5000 psi (350 bar). It is designed with a wet armature setup where the working fluid surrounds the armature, potentially affecting performance if the coil remains energized over extended periods. This model uses EPDM seals suitable for systems using phosphate ester fluids while being incompatible with petroleum-based fluids which can damage these seals. With a flow capacity of up to 5 gpm (20 L/min) and maximum leakage at 110 SUS (24 cSt) being minimal, this valve ensures efficient operation under various conditions. The manual override requires minimal force and offers precise control with just a small stroke needed for activation. The solenoid tube assembly's robust design is fatigue rated for high-pressure applications ensuring durability and reliability. This valve also incorporates Sun Hydraulics' floating style construction which minimizes internal part binding due to installation torque or machining variations in the cavity/cartridge interface. For environments requiring additional protection, various coil connector options rated up to IP69K are available along with weatherized coils and kits.

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.
