The Sun Hydraulics DMDASNV936 (DMDASNV936) is a solenoid-operated 3-way, 2-position cartridge valve that features a direct-acting, balanced spool design for efficient directional control in hydraulic systems. This model includes a soft shift feature designed to minimize hydraulic shock during valve actuation, which is particularly beneficial in applications sensitive to sudden changes in pressure or flow. However, it's important to note that this soft shift may not be suitable for applications requiring precise timing control, where electro-proportional valves might be more appropriate. The DMDASNV936 operates with a typical response time ranging from 150 ms to 300 ms, influenced by factors such as flow rate, pressure, coil voltage, oil viscosity, and ambient temperature. For optimal soft shift performance, it is recommended that port 1 maintains positive pressure. Additionally, the valve is equipped with a push-type manual override control; however, other manual controls are not compatible with the soft shift feature but can be added later if necessary. Constructed for durability and reliability under high-pressure conditions up to 5000 psi (350 bar), the solenoid tube assembly of this model is fatigue rated for demanding applications. The DMDASNV936 uses EPDM seals suitable for systems utilizing phosphate ester fluids; exposure to petroleum-based fluids should be avoided as it can damage these seals. The wet armature design helps in heat management around the coil but could potentially affect fluid integrity over prolonged periods of energization. This unit also incorporates Sun\u2019s floating style construction which helps prevent internal binding due to installation variances or excessive torque application. With coil connector options providing protection ratings up to IP69K and additional weatherized coils available for enhanced environmental resilience, the DMDASNV936 offers flexibility and robustness for a variety of operational environments.

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.
