The Sun Hydraulics DMDASAV72499 (DMDASAV72499) is a solenoid-operated 3-way, 2-position cartridge valve that features a direct-acting, balanced spool design. This model is particularly noted for its soft shift feature, which is designed to significantly reduce shock during valve actuation. Although this soft shift feature increases the response time of the valve (typically ranging from 150 ms to 300 ms), it makes the valve less suitable for applications requiring precise timing control. For such needs, Sun Hydraulics recommends considering their electro-proportional valves instead. The DMDASAV72499 valve includes a push-type manual override and boasts a fatigue rating for up to 5000 psi or 350 bar service. It is important to note that this model should be used with phosphate ester fluids when configured with EPDM seals, as exposure to petroleum-based fluids can damage these seals. The construction of the valve utilizes a wet armature design where the working fluid surrounds the armature, potentially affecting performance if the coil remains energized for extended periods. This model also incorporates Sun's floating style construction which helps minimize internal parts binding due to excessive installation torque or variations in cavity/cartridge machining. The solenoid\u2019s unique magnetic design ensures high efficiency and effective spool actuating force per Watt expended, which contributes to reliable valve shifting. Additionally, various coil connector options are available offering ratings up to IP69K for enhanced environmental protection. With a flow capacity of up to 5 gpm (20 L/min) and maximum operating pressure capability of 5000 psi (350 bar), this valve is well-suited for robust applications requiring reliable directional control and moderate flow handling capabilities.

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.
