The Sun Hydraulics DMDASRNHN24AB (DMDASRNHN24AB) is a high-performance solenoid-operated 3-way, 2-position cartridge valve designed for efficient control in hydraulic systems. This direct-acting, balanced spool directional valve features a unique soft shift functionality that minimizes hydraulic shock during valve actuation, enhancing system longevity and stability. Although the soft shift model offers a slower response time ranging from 150 ms to 300 ms compared to standard solenoids, it is significant in applications sensitive to shock but not reliant on precise timing. Constructed with a wet armature design, the DMDASRNHN24AB allows the working fluid to surround the armature, which can be crucial when the coil is energized over extended periods. This design consideration helps manage the heat generated by the coil but requires attention to fluid selection as some may degrade under prolonged exposure to heat. The valve's robust build includes a fatigue-rated solenoid tube assembly for up to 5000 psi (350 bar) service and features an IP69K-rated coil connector option for enhanced environmental protection against dust and moisture ingress. It also incorporates Sun's floating style construction which reduces risks of internal parts binding due to installation torque or machining variations. Moreover, this model comes equipped with push-type manual override control and supports a maximum flow of 5 gpm (20 L/min) with maximum operating pressure capabilities of 5000 psi (350 bar). The manual override feature requires minimal force yet provides effective manual control in case of electrical power failure or when fine adjustments are needed during maintenance. Overall, the DMDASRNHN24AB is engineered for durability and reliable performance in various hydraulic applications where moderate flow rates and high pressures are involved, making it an essential component for industrial hydraulic systems.

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.
