The Sun Hydraulics DMDASNN924N (DMDASNN924N) is a solenoid-operated 3-way, 2-position cartridge valve that functions as a direct-acting, balanced spool directional valve. This model features a soft shift option designed to mitigate shock from valve actuation, which is particularly useful in applications sensitive to sudden changes in pressure or flow. However, it's important to note that the soft shift does not provide precise timing control necessary for applications requiring exact ramping or timing; for such needs, Sun Hydraulics recommends considering their electro-proportional valves instead. The DMDASNN924N includes a push-type manual override and boasts a fatigue rating suitable for up to 5000 psi (350 bar) service. The valve is engineered with EPDM seals specifically for use with phosphate ester fluids, cautioning against exposure to petroleum-based substances which could degrade the seals. Additionally, this model uses a wet armature design where the working fluid surrounds the armature; prolonged energization of the coil could lead to fluid degradation under high temperatures. With a response time ranging between 150 ms and 300 ms dependent on various factors like flow rate and ambient temperature, this valve adapts well across different operational conditions. It also features Sun's floating style construction which minimizes potential internal binding due to installation torque or machining variations of the cavity/cartridge. The DMDASNN924N is designed for environments requiring robust performance with options for enhanced environmental protection through additional weatherized coils and kits. Its design ensures high efficiency and reliable shifting capabilities owing to its unique magnetic solenoid design. This model is an excellent choice for systems requiring durable and reliable hydraulic control with moderate flow capacities up to 5 gpm (20 L/min) at pressures as high as 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.
