The Sun Hydraulics DMDASBV223 (DMDASBV223) is a high-performance solenoid-operated 3-way, 2-position cartridge valve. This direct-acting, balanced spool directional valve features a soft shift option designed to minimize hydraulic shock during valve actuation, making it suitable for applications sensitive to sudden changes in pressure or flow. The soft shift model offers a slower response time compared to standard cartridges, typically ranging from 150 ms to 300 ms depending on various factors including flow rate and oil viscosity. The valve is designed for easy field installation with manual override options available; however, it's important to note that these manual controls are not compatible with weatherized coils. The valve operates efficiently up to a pressure of 5000 psi (350 bar) and is specifically fatigue rated for such high-pressure conditions. It supports a maximum flow capacity of 5 gpm (20 L/min) and has been engineered to ensure minimal leakage. Notably, the DMDASBV223 utilizes EPDM seals suitable for phosphate ester fluids but should be avoided with petroleum-based fluids which can degrade the seals. The wet armature design of the solenoid exposes the armature to the working fluid, potentially affecting performance if subjected to prolonged heat exposure. Additionally, this model incorporates Sun's innovative floating style construction which reduces the risk of internal parts binding due to improper installation torque or variations in cavity/cartridge machining. This feature ensures more reliable and consistent operation even under varying mechanical stresses. With options for IP69K rated coil connectors and additional kits for environmental protection, this valve is versatile for both general and demanding environments requiring precise fluid control.

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.
