The Sun Hydraulics DMDASPN71299 (DMDASPN71299) is a solenoid-operated, 3-way, 2-position cartridge valve designed for versatile hydraulic applications. This direct-acting, balanced spool directional valve features a unique soft shift control that moderates the shift response to reduce shock from valve actuation, enhancing system longevity and performance stability. Although it provides gentler shifts, it should not be relied on for critical timing applications; instead, Sun's electro-proportional valves are recommended for precise control needs. This model offers a significant increase in response time compared to standard solenoids, with typical response times ranging from 150 ms to 300 ms depending on various factors such as flow rate, pressure, coil voltage, oil viscosity, and ambient temperature. For optimal performance of the soft shift feature, port 1 should maintain positive pressure. Constructed with durability in mind, the DMDASPN71299 includes a push-type manual override and is fatigue rated for services up to 5000 psi (350 bar). The valve's wet armature design means that the working fluid surrounds the armature\u2014this is crucial when considering fluid types as some can degrade under prolonged exposure to heat. Additionally, cartridges configured with EPDM seals are specifically designed for use with phosphate ester fluids; exposure to petroleum-based fluids can damage these seals. The solenoid's efficient magnetic design ensures high spool actuating force per watt expended. This model also incorporates Sun\u2019s floating style construction which minimizes internal parts binding due to installation torque or cavity/cartridge machining variations. It supports a flow capacity of up to 5 gpm (20 L/min) and can handle maximum operating pressures of up to 5000 psi (350 bar). The manual override requires minimal force and has a short stroke length for ease of operation. Various coil connector options are available offering different environmental protection ratings up to IP69K.

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.
