The Sun Hydraulics DMDASAV714 (DMDASAV714) is a solenoid-operated 3-way, 2-position cartridge valve designed for high-efficiency and reliability in hydraulic systems. This direct-acting, balanced spool directional valve features a soft shift option that moderates the shock typically associated with valve actuation. While this soft shift feature extends response times\u2014ranging from 150 ms to 300 ms depending on various factors including flow and pressure\u2014it is not suitable for applications requiring precise timing control, where electro-proportional valves might be more appropriate. This model includes a push-type manual override and is built with a fatigue-rated solenoid tube assembly capable of handling pressures up to 5000 psi (350 bar). The valve's construction incorporates Sun's floating style design which minimizes internal parts binding, ensuring smooth operation even under variable installation conditions. The manual override function is not compatible with weatherized coils, which are also available separately for enhanced environmental protection. The DMDASAV714 utilizes EPDM seals specifically for systems using phosphate ester fluids; exposure to petroleum-based fluids can damage these seals. Its wet armature design means the working fluid surrounds the armature, potentially affecting fluid integrity over prolonged periods of energization. The valve has been engineered to offer high spool actuating force per Watt expended due to its unique magnetic design, thereby ensuring reliable shifting. With an operational capacity of up to 5 gpm (20 L/min) and maximum operating pressure of 5000 psi (350 bar), this valve is well-suited for various hydraulic applications requiring robust performance and moderate flow handling capabilities. Additionally, it offers several coil connector options with ratings up to IP69K for diverse application requirements.

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.
