The Sun Hydraulics DMDASBV72499 (DMDASBV72499) is a high-performance solenoid-operated 3-way, 2-position cartridge valve that features a direct-acting, balanced spool design. This model is specifically engineered to offer a soft shift option which minimizes hydraulic shock during valve actuation. Although it provides a smoother transition compared to standard cartridges, it's essential to note that its response times are longer, typically ranging from 150 ms to 300 ms depending on various factors like flow, pressure, and ambient temperature. The DMDASBV72499 boasts a manual override feature with a push-type control for emergency or manual operations. However, this functionality is not compatible with weatherized coils. The valve operates efficiently within systems that maintain port 1 at positive pressure to ensure consistent performance of the soft shift mechanism. Designed for durability and robust operation in demanding environments, the solenoid tube assembly of this model is fatigue rated for up to 5000 psi (350 bar). It also incorporates Sun Hydraulics' floating style construction which helps prevent internal parts binding due to installation torque or cavity/cartridge machining variations. This cartridge valve is suitable for use with phosphate ester fluids thanks to its EPDM seals; however, exposure to petroleum-based fluids can damage these seals. The wet armature design means that the working fluid surrounds the armature which could be a consideration if the coil remains energized for extended periods. Additional technical specifications include a maximum operating pressure of 5000 psi (350 bar), flow capacity up to 5 gpm (20 L/min), and maximum leakage at 3000 psi not exceeding 80 cc/min (210 bar). The model also features various installation and operational dimensions such as a solenoid tube diameter of .75 inches (19 mm) and an installation torque between 30 \u2013 35 lbf\u00b7ft (41 \u2013 47 Nm).

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.
