The Sun Hydraulics DMDASNN714 (DMDASNN714) is a solenoid-operated 3-way, 2-position cartridge valve, designed for direct-acting, balanced spool directional control. It features a soft shift option that moderates the hydraulic shock during valve actuation, although it is not suitable for applications requiring precise timing control. This model offers a slower response time compared to standard solenoids, typically ranging from 150 ms to 300 ms, which varies with flow, pressure, coil voltage, oil viscosity, and ambient temperature. Additionally, the DMDASNN714 includes a push-type manual override control and has an installation requirement where port 1 must maintain positive pressure for optimal performance. The valve's solenoid tube assembly is rated for fatigue at up to 5000 psi (350 bar). It is important to note that cartridges with EPDM seals are specifically designed for phosphate ester fluids; exposure to petroleum-based fluids can damage these seals. This model also benefits from a wet armature design where the working fluid surrounds the armature. Prolonged energization of the coil can lead to fluid degradation at high temperatures. The magnetic design of the solenoid ensures high efficiency and robust valve shifting capabilities. The DMDASNN714 also incorporates Sun's floating style construction which helps prevent internal parts binding due to excessive installation torque or variations in cavity-cartridge machining. In terms of physical specifications, this model has a flow capacity of up to 5 gpm (20 L/min) and can handle maximum operating pressures up to 5000 psi (350 bar). The manual override requires a force of about 5 lbs at 1000 psi on port 1 and allows for a stroke of .10 inches (2.5 mm). The solenoid tube diameter measures .75 inches (19 mm), and it requires an installation torque between 30 - 35 lbf-ft (41 - 47 Nm). The overall weight of the valve is approximately .60 lb (0.30 kg). For environmental protection against harsh conditions, additional weatherized coils and kits are available as well as various coil connector options with 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.
