The Sun Hydraulics DMDASPN814 (DMDASPN814) is a solenoid-operated 3-way, 2-position cartridge valve designed for hydraulic applications requiring directional control. This direct-acting, balanced spool valve offers a soft shift feature to minimize hydraulic shock during valve actuation. However, it is not suitable for applications where precise timing control is critical; for such needs, electroproportional valves are recommended. The soft shift also increases the response time of the valve, typically ranging from 150 ms to 300 ms depending on various factors like flow rate and oil viscosity. With a maximum operating pressure of 5000 psi (350 bar) and a flow capacity of up to 5 gpm (20 L/min), this model ensures robust performance in demanding environments. The valve features manual override capabilities with a push-type control, although it should be noted that weatherized coils are not compatible with this functionality. It also includes options for EPDM seals suitable for phosphate ester fluids but should not be used with petroleum-based fluids which can damage the seals. The construction of the DMDASPN814 incorporates Sun\u2019s floating style design to prevent internal parts binding due to installation issues or cavity/cartridge machining variations. The solenoid design is highly efficient, providing strong actuating force per watt expended which facilitates reliable valve shifting. Additionally, coil connector options can achieve ratings up to IP69K for enhanced environmental protection. This model's manual override requires a force of about 5 lbs at 1000 psi at port 1 and has a stroke length of .10 inches (2.5 mm). The solenoid tube diameter measures .75 inches (19 mm), and the valve itself has an installation torque range of 30-35 lbf ft (41-47 Nm), weighing approximately .60 lb (0.30 kg). This compact yet powerful configuration makes the DMDASPN814 ideal for various hydraulic systems where space and reliability are critical considerations.

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.
