The Sun Hydraulics DMDASAVHN24AB (DMDASAVHN24AB) is a solenoid-operated 3-way, 2-position cartridge valve designed for high-efficiency hydraulic systems. Featuring a direct-acting, balanced spool design, this valve ensures reliable control of fluid flow in various applications. Its soft shift feature is engineered to minimize hydraulic shock during valve actuation, which is particularly beneficial in systems where sudden changes in pressure could cause damage or undesired reactions. However, it's noted that this soft shift does not provide precise timing control which might be necessary for some applications; for such cases, Sun Hydraulics recommends considering their electro-proportional valves instead. This model incorporates a wet armature design allowing the working fluid to surround the armature. While this aids in cooling and efficient operation, prolonged energization can lead to fluid degradation at high temperatures, potentially affecting performance. The solenoid\u2019s unique magnetic design enhances its efficiency, translating to higher spool actuating force per watt expended and ensuring consistent and reliable valve shifting. The DMDASAVHN24AB has a maximum operating pressure of 5000 psi and supports flows up to 5 gpm (20 L/min), making it suitable for a variety of heavy-duty applications. It also features manual override capabilities with push-type control and is compatible with EPDM seals for phosphate ester fluids; however, exposure to petroleum-based fluids should be avoided as it can damage the seals. Designed with Sun Hydraulics' floating style construction, the valve minimizes potential internal parts binding due to installation torque or machining variations of the cavity/cartridge. This model also offers various coil connector options with ratings up to IP69K for enhanced environmental protection against dust and moisture ingress, ensuring durability and long-term performance in harsh conditions.

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.
