The Sun Hydraulics DMDASAV512 (DMDASAV512) is a high-performance solenoid-operated 3-way, 2-position cartridge valve designed for precise hydraulic flow control. This direct-acting, balanced spool directional valve is engineered to facilitate smooth and gradual starts and stops in hydraulic systems, minimizing shock from valve actuation through its soft shift feature. Although the soft shift model offers a slower response time ranging between 150 ms to 300 ms compared to standard solenoids, it significantly enhances system longevity by reducing mechanical stress. The DMDASAV512 supports up to 5 gpm/20 L/min flow capacity and can withstand a maximum operating pressure of 5000 psi/350 bar. This model includes a push-type manual override control, providing an alternative operation method which is not compatible with weatherized coils. The manual override requires a force of about 5 lbs at 1000 psi for port 1 activation and has a stroke length of .10 inches (2.5 mm). Constructed with durability in mind, the solenoid tube assembly of the DMDASAV512 is fatigue rated for high-pressure applications. It features EPDM seals suitable for use with phosphate ester fluids; however, these seals must not be exposed to petroleum-based substances which could cause damage. Additionally, the valve employs a wet armature design where the working fluid envelops the armature, potentially affecting fluid integrity under prolonged energization. For environmental resilience, various coil connector options rated up to IP69K are available to protect against harsh conditions. The cartridge also incorporates Sun\u2019s floating style construction which minimizes internal binding caused by excessive installation torque or cavity/cartridge machining discrepancies. Overall, the Sun Hydraulics DMDASAV512 offers robust performance and reliability for specialized hydraulic applications requiring controlled motion and reduced operational shock.

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.
