The Sun Hydraulics DMDASRN72499 (DMDASRN72499) is a solenoid-operated 3-way, 2-position cartridge valve characterized by its direct-acting, balanced spool design. This model incorporates a soft shift feature designed to mitigate shock during valve actuation, although it is not suitable for applications requiring critical timing or precise ramping control. The valve's response time varies between 150 ms to 300 ms depending on factors such as flow, pressure, coil voltage, oil viscosity, and ambient temperature. To ensure optimal performance of the soft shift feature, port 1 should maintain positive pressure. This model also includes a push-type manual override control that is incompatible with weatherized coils but can be substituted with other manual controls like T or D in the field. The solenoid tube assembly of this valve is fatigue rated for service up to 5000 psi (350 bar). It is important to note that cartridges equipped with EPDM seals are specifically designed for systems using phosphate ester fluids and will degrade if exposed to petroleum-based substances. The wet armature design utilized in this model means the working fluid surrounds the armature which could lead to fluid breakdown if the coil remains energized for extended periods. This valve also boasts a high-efficiency solenoid providing strong spool actuating force per watt expended, ensuring reliable shifting. Additional features include various coil connector options rated up to IP69K for enhanced environmental protection and Sun\u2019s floating style construction which minimizes internal parts binding due to installation torque or cavity/cartridge machining variations. The DMDASRN72499 operates at a capacity of 5 gpm (20 L/min) with a maximum operating pressure of 5000 psi (350 bar). It has been designed for minimal leakage and features manual override capabilities requiring minimal force. This model's robust construction and versatile design make it suitable for diverse applications where moderate flow directional control is needed.

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.
