The Sun Hydraulics DMDASRV612 (DMDASRV612) is a high-performance solenoid-operated 3-way, 2-position cartridge valve designed for efficient control in hydraulic systems. This direct-acting, balanced spool directional valve features a unique soft shift capability that minimizes shock during valve actuation, enhancing system longevity and reducing potential damage from hydraulic spikes. However, it is important to note that while the soft shift feature improves response smoothness, it may not be suitable for applications requiring precise timing or ramping control, where electro-proportional valves would be more appropriate. The DMDASRV612 boasts a typical response time ranging from 150 ms to 300 ms, dependent on various factors including flow rate, pressure levels, coil voltage, oil viscosity, and ambient temperature conditions. For optimal performance of the soft shift feature, it's recommended that port 1 maintains positive pressure. This model includes a push-type manual override control but is incompatible with weatherized coils when using this functionality. It also features a fatigue-rated solenoid tube assembly capable of handling up to 5000 psi (350 bar), making it robust for high-pressure applications. The valve uses EPDM seals specifically designed for phosphate ester fluids; exposure to petroleum-based fluids can damage these seals. Additionally, the DMDASRV612 employs a wet armature design which allows the working fluid to surround the armature. This design consideration is crucial as prolonged energization can lead to heat buildup potentially affecting fluid integrity over time. With coil connector options providing ratings up to IP69K and additional weatherized coils available for enhanced environmental protection, this model ensures reliable operation even in demanding conditions. The floating style construction of the valve aids in preventing internal parts binding due to excessive installation torque or cavity/cartridge machining variations.

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.
