The Sun Hydraulics DMDASNVHN24AB (DMDASNVHN24AB) is a high-performance solenoid-operated 3-way, 2-position cartridge valve designed for efficient directional control in hydraulic systems. This direct-acting, balanced spool valve features a unique soft shift capability that moderates hydraulic shock during valve actuation, enhancing system longevity and performance stability. Although the soft shift feature increases response times (typically ranging from 150 ms to 300 ms), it significantly mitigates the risks associated with sudden pressure spikes in fluid power applications. The valve is engineered with a wet armature design, allowing the working fluid to surround the armature which may be a consideration if the coil remains energized for extended periods. The heat generated under such conditions can affect certain hydraulic fluids, potentially leading to varnish formation that could impair cartridge functionality. This model also boasts a robust solenoid tube assembly rated for up to 5000 psi (350 bar), making it suitable for high-pressure applications. With its floating style construction, the DMDASNVHN24AB minimizes internal part binding due to excessive installation torque or cavity/cartridge machining variations, ensuring reliable operation and ease of installation. The manual override feature of this model provides additional operational flexibility, although it is not compatible with weatherized coils. Configured with EPDM seals, this valve is specifically intended for systems using phosphate ester fluids; exposure to petroleum-based fluids should be avoided as it would damage the seals. For environments requiring stringent protection against elements, additional weatherized coils and kits are available. This compact yet powerful valve also supports various coil connector options with ratings up to IP69K for enhanced environmental resilience. Whether used in standalone or integrated system configurations, the Sun Hydraulics DMDASNVHN24AB offers reliable control and adaptability across a range of hydraulic applications.

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.
