The Sun Hydraulics DMDASBN924 (DMDASBN924) is a solenoid-operated 3-way, 2-position cartridge valve featuring a direct-acting, balanced spool design. This model is specifically engineered to offer a soft shift option, which significantly reduces shock during valve actuation, although it is not suitable for applications requiring precise timing control. The soft shift feature increases the response time of the valve, typically ranging between 150 ms to 300 ms, depending on various factors including flow, pressure, coil voltage, oil viscosity, and ambient temperature. This valve maintains consistent performance when port 1 is under positive pressure and includes a push-type manual override control. It should be noted that other manual control options are not compatible with the soft shift feature but can be added in the field if necessary. The valve's solenoid tube assembly is designed to handle up to 5000 psi (350 bar), making it fatigue rated for high-pressure applications. Constructed with EPDM seals, this cartridge is suitable for systems using phosphate ester fluids; however, exposure to petroleum-based fluids can damage these seals. The wet armature design of the solenoid means that the working fluid surrounds the armature which could lead to fluid breakdown in cases of prolonged energization. This model also benefits from Sun Hydraulics' floating style construction which minimizes internal parts binding due to installation variances or machining discrepancies. Additionally equipped with weather-resistant coil connector options up to IP69K and optional weatherized coils for enhanced environmental protection, this model offers versatility across various operational environments. The DMDASBN924 provides a robust solution for hydraulic systems requiring reliable directional control with moderate flow handling capabilities of up to 5 gpm (20 L/min) and maximum operating pressures of 5000 psi (350 bar).

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.
