The Sun Hydraulics DMDASBV72419 (DMDASBV72419) is a solenoid-operated 3-way, 2-position cartridge valve that functions as a direct-acting, balanced spool directional valve. It features a soft shift option designed to minimize hydraulic shock during valve actuation, although it is not suitable for applications where precise timing control is critical. For such needs, electro-proportional valves are recommended. The soft shift model exhibits an increased response time compared to standard solenoids, typically ranging from 150 ms to 300 ms, influenced by various factors including flow rate, pressure, coil voltage, oil viscosity, and ambient temperature. This model's manual override is a push-type control; other manual controls are compatible but require field installation. The valve's solenoid tube assembly is rated for fatigue at pressures up to 5000 psi (350 bar). It uses EPDM seals suitable for phosphate ester fluids but incompatible with petroleum-based substances which can degrade the seals. The wet armature design of this model means that the working fluid surrounds the armature which could be a consideration if the coil remains energized for extended periods. Additionally, this model incorporates Sun\u2019s floating style construction which helps prevent internal parts binding caused by excessive installation torque or variations in cavity/cartridge machining. With port capacities up to 5 gpm (20 L/min) and maximum operating pressures of 5000 psi (350 bar), this valve ensures robust performance in various hydraulic applications. The design also includes multiple coil connector options with ratings up to IP69K for enhanced environmental protection against dust and water ingress under severe conditions.

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.
