The Sun Hydraulics DMDASRN514 (DMDASRN514) is a solenoid-operated, 3-way, 2-position cartridge valve featuring a direct-acting, balanced spool design. This model is specifically engineered to offer a soft shift option which significantly reduces shock during valve actuation. Although it provides smoother transitions, the soft shift model has slower response times ranging from 150 ms to 300 ms compared to standard solenoids, influenced by factors such as flow rate, pressure, coil voltage, oil viscosity, and ambient temperature. This makes it less suitable for applications requiring precise timing control. The DMDASRN514 incorporates a push-type manual override and boasts an impressive fatigue rating for the solenoid tube assembly at 5000 psi (350 bar). It should be noted that cartridges with EPDM seals are intended for systems using phosphate ester fluids; exposure to petroleum-based products can damage these seals. The valve's wet armature design means it's crucial to consider the thermal effects of prolonged energization on the working fluid. Additionally, this model features Sun\u2019s floating style construction which minimizes internal binding due to installation torque or machining variations in the cavity/cartridge interface. The valve supports a maximum operating pressure of 5000 psi (350 bar) and has a flow capacity of up to 5 gpm (20 L/min). The manual override requires minimal force and offers simple stroke adjustments. For environmental durability, various coil connector options rated up to IP69K are available along with additional weatherized coils and kits for enhanced protection against harsh conditions. This combination of features makes the DMDASRN514 an adaptable solution for diverse hydraulic system applications where smooth operational transitions are prioritized over rapid actuation.

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.
