The Sun Hydraulics DMDASPN814N (DMDASPN814N) is a solenoid-operated 3-way, 2-position cartridge valve designed for direct-acting, balanced spool directional control. This model features a soft shift option which moderates the shock typically associated with valve actuation, although it is not recommended for applications requiring precise timing control. The soft shift variant has an extended response time compared to standard solenoids, varying from 150 ms to 300 ms based on several factors including flow, pressure, and ambient temperature. Equipped with a push-type manual override control, this valve does not support other manual control options like T or D when configured with soft shift controls; however, these can be added in the field if needed. The manual override feature is incompatible with weatherized coils. The valve's solenoid tube assembly is robustly designed to handle up to 5000 psi or 350 bar service and incorporates EPDM seals suitable for phosphate ester fluids but vulnerable to damage by petroleum-based substances. This model also employs a wet armature design where the working fluid surrounds the armature. Extended coil energization can lead to heat build-up affecting fluid integrity over time, especially in water-glycol mixtures. With its high-efficiency magnetic design, the solenoid ensures effective spool actuation force per watt expended. Connection options for the coil connector are rated up to IP69K for enhanced environmental protection. The DMDASPN814N also benefits from Sun's floating style construction which helps minimize internal part binding due to installation variances or excessive torque. This model supports a maximum flow of 5 gpm/20 L/min and can handle pressures up to 5000 psi/350 bar with minimal leakage. Its compact design includes thoughtful details like a .75 inch solenoid tube diameter and requires an installation torque between 30 - 35 lbf ft.

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.
