The Sun Hydraulics DMDASPN636 (DMDASPN636) is a solenoid-operated 3-way, 2-position cartridge valve designed for use in hydraulic systems. This direct-acting, balanced spool directional valve features a soft shift option that moderates the shock typically associated with valve actuation, making it suitable for applications sensitive to such disturbances. However, it is noted that this soft shift feature should not be relied upon for critical timing applications; instead, Sun's electro-proportional valves are recommended for scenarios requiring precise control over ramping or timing. The valve\u2019s response time varies between 150 ms to 300 ms depending on factors like flow rate, pressure, coil voltage, oil viscosity, and ambient temperature. For optimal performance of the soft shift functionality, it is advised that port 1 maintains positive pressure. The model also includes a push-type manual override control but is incompatible with weatherized coils when using this feature. Constructed to handle pressures up to 5000 psi (350 bar), the DMDASPN636 uses EPDM seals specifically suited for systems utilizing phosphate ester fluids; exposure to petroleum-based substances can damage these seals. The wet armature design of the solenoid ensures that the working fluid surrounds the armature which could be a consideration if the coil remains energized over extended periods due to potential breakdowns in certain fluid types at high temperatures. This model also benefits from Sun Hydraulics' floating style construction which minimizes internal part binding caused by excessive installation torque or variations in cavity/cartridge machining. With additional options available for coil connectors up to IP69K and various weatherized coils and kits, this valve offers robust configuration choices for diverse environmental conditions.

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.
