The Sun Hydraulics DMDASPN914 (DMDASPN914) is a high-performance, solenoid-operated 3-way, 2-position cartridge valve designed for hydraulic systems. This direct-acting, balanced spool directional valve features a soft shift option that moderates the shock typically associated with valve actuation. Although not suitable for applications where precise timing control is critical, its soft shift capability makes it an excellent choice for systems where shock reduction is a priority. The valve's response time varies between 150 ms to 300 ms depending on factors such as flow rate, pressure, coil voltage, oil viscosity, and ambient temperature. It includes a push-type manual override control; however, other manual control options like T or D are not compatible with the soft shift feature but can be added in the field if necessary. It\u2019s important to note that the manual override function does not work with weatherized coils. Rated for up to 5000 psi (350 bar), the solenoid tube assembly of this valve is fatigue rated for demanding applications. The DMDASPN914 uses EPDM seals specifically designed for use with phosphate ester fluids; exposure to petroleum-based fluids can damage these seals. The wet armature design ensures that the working fluid surrounds the armature which helps in cooling but could degrade certain types of hydraulic fluids over prolonged periods. This model also features Sun's unique magnetic design which enhances solenoid efficiency and provides strong spool actuating force per watt expended, ensuring reliable operation and shifting of the valve. Furthermore, it incorporates Sun\u2019s floating style construction which minimizes internal parts binding \u2014 a common issue caused by excessive installation torque or variations in cavity/cartridge machining. With additional options like weatherized coils and IP69K rated coil connectors available for enhanced environmental protection, this versatile cartridge valve adapts well to various operational conditions while maintaining robust performance and reliability.

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.
