The Sun Hydraulics DMDASBN624N (DMDASBN624N) is a solenoid-operated 3-way, 2-position cartridge valve that offers a direct-acting, balanced spool directional control. This model, designed for a maximum operating pressure of 5000 psi (350 bar) and a flow capacity of up to 5 gpm (20 L/min), is engineered for high-performance hydraulic systems. The valve features an innovative soft shift control which moderates the shock typically associated with valve actuation. Although this feature increases response times\u2014typically ranging between 150 ms to 300 ms\u2014it is crucial in applications aiming to minimize system shocks rather than those requiring precise timing or ramping control. Equipped with a push-type manual override, the DMDASBN624N allows for manual operation in scenarios where electronic control may not be feasible. However, it's important to note that this function is incompatible with weatherized coils, limiting its use under certain environmental conditions. The cartridge also incorporates Sun Hydraulics' floating style construction, which reduces the risk of internal parts binding due to improper installation torque or variations in cavity/cartridge machining. This valve utilizes EPDM seals suitable for phosphate ester fluids but vulnerable to damage when exposed to petroleum-based substances. Its wet armature design means that the working fluid surrounds the armature; prolonged energization of the coil could lead to fluid degradation at high temperatures. Additionally, the solenoid's unique magnetic design enhances efficiency, providing robust spool actuation force per watt expended and ensuring reliable operation even under demanding conditions. The DMDASBN624N also supports various coil connector options with ratings up to IP69K for enhanced environmental protection, making it versatile for a wide range of hydraulic applications needing robust and reliable directional control.

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.
