The Sun Hydraulics DMDASPN514 (DMDASPN514) is a high-performance solenoid-operated 3-way, 2-position cartridge valve designed for use in hydraulic systems. This direct-acting, balanced spool directional valve features a unique soft shift control that moderates hydraulic shock during valve actuation. The soft shift feature, while reducing system shocks significantly, is not suitable for applications requiring precise timing or ramping control; for such needs, Sun Hydraulics recommends their electro-proportional valves. The valve's performance and response times are influenced by several factors including flow rate, pressure, coil voltage, oil viscosity, and ambient temperature. Typical response times range from 150 ms to 300 ms. It is essential that port 1 maintains positive pressure to ensure consistent soft shift performance. Additionally, this model includes a push-type manual override control which is not compatible with weatherized coils but can be substituted with other manual controls in the field if necessary. Constructed with durability in mind, the solenoid tube assembly of the DMDASPN514 is fatigue rated for up to 5000 psi (350 bar) service. The valve employs EPDM seals specifically designed for phosphate ester fluids; exposure to petroleum-based fluids can damage these seals. Its wet armature design means that the working fluid surrounds the armature which could be a consideration if the coil remains energized for extended periods as some fluids may degrade under prolonged heat exposure. This model also features a high-efficiency solenoid that ensures reliable valve shifting by producing high spool actuating force per watt expended. The floating style construction of the cartridge minimizes internal parts binding caused by excessive installation torque or cavity/cartridge machining variations. For environmental protection in harsh conditions, additional weatherized coils and kits are available. With an IP69K rating option for coil connectors and robust manual override features, this valve offers both flexibility and reliability in challenging industrial applications.

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.
