The Sun Hydraulics DMDASPN72419 (DMDASPN72419) is a high-performance solenoid-operated 3-way, 2-position cartridge valve that features a direct-acting, balanced spool design. This model incorporates a soft shift feature designed to mitigate shock resulting from valve actuation, although it is not suitable for applications requiring precise timing control, which are better served by electroproportional valves. The valve's response time varies from 150 ms to 300 ms depending on several factors including flow, pressure, coil voltage, oil viscosity, and ambient temperature. The DMDASPN72419 is built with a push-type manual override control and does not support other manual control options when configured with soft shift control. Its solenoid tube assembly is fatigue rated for up to 5000 psi or 350 bar service. The valve is compatible with EPDM seals for use with phosphate ester fluids; however, exposure to petroleum-based fluids can damage these seals. This model also benefits from Sun Hydraulics' floating style construction which minimizes internal parts binding due to excessive installation torque or machining variations in the cavity/cartridge. Additionally, the solenoid's unique magnetic design enhances efficiency and provides a robust spool actuating force per Watt expended. For environmental protection in harsh conditions, weatherized coils and kits are available. Key specifications include a maximum operating pressure of 5000 psi or 350 bar and a capacity of up to 5 gpm or 20 L/min. The valve also features an IP69K rating for coil connectors ensuring high resistance against dust and water ingress under severe conditions. This makes the DMDASPN72419 an ideal choice for various hydraulic applications where reliability and performance are critical.

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.
