The Sun Hydraulics DMDASAV299 (DMDASAV299) is a solenoid-operated 3-way, 2-position cartridge valve designed for efficient hydraulic flow control. This direct-acting, balanced spool directional valve features a unique soft shift mechanism that mitigates hydraulic shock during valve actuation, enhancing system longevity and reducing potential damage to hydraulic components. Although the soft shift design increases response times (typically ranging from 150 ms to 300 ms), it is not suitable for applications requiring precise timing control, such as those needing accurate ramping. The DMDASAV299 incorporates a wet armature design where the working fluid surrounds the armature. This design consideration is crucial as prolonged energization of the coil heats the fluid, potentially affecting fluid properties and valve performance over time. Notably, this model uses EPDM seals which are compatible with phosphate ester fluids but can be damaged by exposure to petroleum-based fluids. This model also features manual override capabilities with a push-type control; however, it's important to note that other manual control options are not compatible with the soft shift feature but can be retrofitted in the field if necessary. The valve's solenoid tube assembly is fatigue rated at 5000 psi (350 bar), ensuring robust performance under high-pressure conditions. Designed for maximum environmental resilience, the DMDASAV299 offers coil connector options up to IP69K and supports additional weatherized coils for enhanced protection against harsh conditions. The valve also benefits from Sun Hydraulics' floating style construction which minimizes internal part binding due to installation or machining variances, thus ensuring reliable operation and extended service life. With a flow 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 demanding hydraulic applications requiring efficient flow direction control and shock mitigation.

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.
