The Sun Hydraulics DMDASBN228 (DMDASBN228) is a high-performance solenoid-operated 3-way, 2-position cartridge valve designed for hydraulic systems. This direct-acting, balanced spool directional valve is engineered to provide reliable control of fluid flow in various applications. Its unique soft shift feature is specifically designed to minimize hydraulic shock during valve actuation, which enhances system longevity and reduces potential damage to sensitive components. However, it's important to note that for applications requiring precise timing control, Sun Hydraulics recommends considering their electro-proportional valves instead. The DMDASBN228 model offers a typical response time ranging from 150 ms to 300 ms, dependent on variables such as flow rate, pressure, coil voltage, oil viscosity, and ambient temperature conditions. The valve\u2019s construction includes a wet armature design where the working fluid surrounds the armature\u2014this aspect is crucial as it can influence the fluid's properties if the coil remains energized over extended periods. This model features a manual override control of the push-type variety and boasts a robust solenoid tube assembly rated for up to 5000 psi (350 bar). It's essential for users to ensure that port 1 maintains positive pressure for consistent performance of the soft shift functionality. Additionally, this valve uses EPDM seals suitable for systems with phosphate ester fluids; exposure to petroleum-based fluids should be avoided as it can damage these seals. In terms of durability and environmental resistance, the DMDASBN228 includes options for weatherized coils and possesses IP69K-rated coil connector options. The floating style construction incorporated into its design helps prevent internal parts binding due to installation torque or machining variations in the cavity/cartridge setup. This model supports a maximum operating pressure of 5000 psi (350 bar) and has a flow capacity up to 5 gpm (20 L/min), making it a versatile choice for various hydraulic applications requiring dependable performance and gentle operational characteristics.

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.
