The Sun Hydraulics DMDASBN (DMDASBN) is a solenoid-operated 3-way, 2-position cartridge valve featuring a direct-acting, balanced spool directional control. Designed for hydraulic applications, this model includes a soft shift feature that moderates the impact of valve actuation, reducing system shocks significantly although it is not suitable for applications requiring precise timing control. The valve operates with typical response times ranging from 150 ms to 300 ms depending on various factors such as flow, pressure, and ambient temperature. It is recommended that port 1 maintains positive pressure to ensure consistent performance of the soft shift functionality. The manual override option included is a push-type control; however, other manual controls like T or D are available but need installation in the field. This model's solenoid tube assembly is fatigue rated for up to 5000 psi (350 bar) service. The cartridge uses EPDM seals designed specifically for systems utilizing phosphate ester fluids; these seals are prone to damage if exposed to petroleum-based substances. Additionally, the DMDASBN utilizes a wet armature design where the working fluid surrounds the armature which can affect fluid integrity under prolonged energization. The solenoid design ensures high efficiency and reliable valve operations due to its high spool actuating force per watt expended. For environmental protection options, weatherized coils and kits are available that can enhance durability in challenging conditions. This valve has an operating capacity of up to 5 gpm (20 L/min) and can handle maximum operating pressures of up to 5000 psi (350 bar). Its construction incorporates Sun's floating style design which minimizes internal part binding risks due to installation or machining variations. With features like IP69K rated coil connector options and a robust build quality, the Sun Hydraulics DMDASBN offers reliable performance for hydraulic systems requiring moderate flow directional control with enhanced shock mitigation capabilities.

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.
