The Sun Hydraulics DMDASRN936 (DMDASRN936) is a solenoid-operated 3-way, 2-position cartridge valve designed for hydraulic systems. This direct-acting, balanced spool directional valve features a soft shift option that moderates the impact of valve actuation, reducing system shocks significantly. Although it offers smoother transitions compared to standard cartridges, it is not suitable for applications requiring precise timing control, such as those needing exact ramping or timing adjustments. The DMDASRN936 operates optimally when port 1 maintains positive pressure and includes a push-type manual override control. This manual override is not compatible with weatherized coils but can be substituted with other manual control options in the field if necessary. The valve's design incorporates fatigue-rated solenoid tube assembly for up to 5000 psi (350 bar) service and features an efficient magnetic design that ensures reliable spool actuation with high force per Watt expended. This model uses EPDM seals suited for phosphate ester fluids; however, these seals are vulnerable to damage from exposure to petroleum-based substances. Additionally, its wet armature design means the working fluid surrounds the armature which may affect performance if exposed to prolonged heat from coil energization. For environmental resilience, the DMDASRN936 offers coil connector options rated up to IP69K and additional weatherized coils and kits are available for enhanced protection. The cartridge also benefits from Sun\u2019s floating style construction which minimizes internal binding risks due to installation torque or machining variations of cavity/cartridge. The device supports a flow capacity of up to 5 gpm (20 L/min) and can handle pressures up to 5000 psi (350 bar), making it a robust choice for various hydraulic applications where shock mitigation is beneficial but not critical for system operation.

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.
