The Sun Hydraulics DMDASRV214 (DMDASRV214) is a solenoid-operated 3-way, 2-position cartridge valve designed for precise hydraulic fluid direction control. This direct-acting, balanced spool directional valve features a soft shift option that moderates the shock typically associated with valve actuation. Although beneficial for reducing system shocks, this feature is not recommended for applications where precise timing control is critical. For those needs, electro-proportional valves might be more suitable. The DMDASRV214 operates with a typical response time ranging from 150 ms to 300 ms, influenced by factors such as flow rate, pressure, coil voltage, oil viscosity, and ambient temperature. It is essential to maintain positive pressure at port 1 to ensure consistent performance of the soft shift function. Additionally, this model includes a push-type manual override control and is incompatible with other manual controls when soft shift is used; however, these can be installed in the field if necessary. Constructed to handle up to 5000 psi (350 bar), the solenoid tube assembly of the DMDASRV214 is fatigue rated for high-pressure applications. The valve's wet armature design means that it should be monitored if energized continuously due to potential heat effects on certain hydraulic fluids. It incorporates Sun's floating style construction which minimizes internal part binding due to installation or machining discrepancies. This model uses EPDM seals specifically suited for phosphate ester fluids; exposure to petroleum-based substances can damage these seals. Various coil connector options are available providing up to IP69K protection rating with additional weatherized coils and kits offered for enhanced environmental safeguarding. The DMDASRV214 supports up to 5 gpm (20 L/min) flow capacity and features robust manual override functionalities requiring minimal force. With its compact design and efficient magnetic structure that maximizes actuating force per watt expended, this valve ensures reliable operation across varied hydraulic 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.
