The Sun Hydraulics DMDASNN914N (DMDASNN914N) is a solenoid-operated 3-way, 2-position cartridge valve featuring a direct-acting, balanced spool design. It is engineered with a soft shift feature to mitigate shock during valve actuation, though it is not suitable for applications requiring precise timing control. This model offers slower response times compared to standard solenoids\u2014typically ranging from 150 ms to 300 ms\u2014affected by factors such as flow rate, pressure, coil voltage, oil viscosity, and ambient temperature. The cartridge allows for manual override with a push-type control; however, this functionality cannot be combined with weatherized coils. The valve\u2019s solenoid tube assembly is fatigue rated for up to 5000 psi (350 bar), ensuring robust performance in demanding conditions. Importantly, cartridges configured with EPDM seals are specifically designed for systems using phosphate ester fluids and must avoid exposure to petroleum-based substances which could degrade the seals. This model also features a wet armature design where the working fluid surrounds the armature. This can lead to fluid breakdown and varnish formation if the coil remains energized excessively. The DMDASNN914N boasts an efficient magnetic design that maximizes spool actuating force per watt expended, facilitating reliable valve shifting. It includes options for coil connectors up to IP69K rating for enhanced environmental protection. Constructed using Sun\u2019s floating style architecture, the valve minimizes internal parts binding that could result from excessive installation torque or variations in cavity/cartridge machining. This product supports a maximum operating pressure of 5000 psi (350 bar) and handles flow capacities up to 5 gpm (20 L/min), with maximum leakage specifications detailed at 5 in\u00b3/min at 3000 psi (80 cc/min at 210 bar). The manual override requires minimal force and has a stroke length of .10 inches (2.5 mm), making operation straightforward and efficient even under high-pressure conditions.

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.
