The Sun Hydraulics DMDASRV72499 (DMDASRV72499) is a solenoid-operated 3-way, 2-position cartridge valve designed for precise hydraulic fluid direction control. This direct-acting, balanced spool directional valve features a soft shift option that moderates the shock typically associated with valve actuation, making it suitable for applications sensitive to sudden changes in pressure. However, it is not ideal for uses requiring critical timing or accurate ramping, where electroproportional valves might be more appropriate. The valve's soft shift design increases response times, generally ranging from 150 ms to 300 ms depending on various factors like flow rate, pressure, coil voltage, oil viscosity, and ambient temperature. It is recommended that port 1 maintains positive pressure to ensure consistent performance of the soft shift feature. Additionally, this model includes a push-type manual override control but is incompatible with weatherized coils when using this functionality. Constructed to handle up to 5000 psi (350 bar), the solenoid tube assembly of the DMDASRV72499 is fatigue rated for high-pressure applications. The wet armature design of the valve means that the working fluid envelops the armature which could lead to heat-related degradation of certain hydraulic fluids over extended periods. It's also important to note that cartridges with EPDM seals should only be used with phosphate ester fluids as exposure to petroleum-based substances can damage these seals. This model also incorporates Sun Hydraulics' floating style construction which minimizes internal parts binding caused by excessive installation torque or variances in cavity/cartridge machining. The unit supports a variety of coil connector options with ratings up to IP69K for enhanced environmental protection. With a maximum flow capacity of 5 gpm (20 L/min) and featuring robust manual override capabilities, the DMDASRV72499 offers reliable performance and versatility in controlling hydraulic fluid direction in diverse settings.

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.
