The Sun Hydraulics DMDASRN912 (DMDASRN912) is a high-performance solenoid-operated 3-way, 2-position cartridge valve designed for various hydraulic applications. This direct-acting, balanced spool directional valve features a unique soft shift capability, which moderates the shock typically associated with valve actuation. Although this feature enhances the smooth operation of hydraulic systems, it is not suitable for applications requiring precise timing control, such as those needing exact ramping or timing adjustments. The DMDASRN912 operates optimally when port 1 maintains positive pressure and has a typical response time ranging from 150 ms to 300 ms, influenced by factors like flow rate, pressure, coil voltage, oil viscosity, and ambient temperature. The valve's solenoid tube assembly is fatigue rated for up to 5000 psi (350 bar), ensuring robust performance even under high-pressure conditions. It also incorporates Sun Hydraulics' floating style construction which minimizes internal parts binding due to installation torque or cavity/cartridge machining variations. This model includes a push-type manual override control and offers multiple coil connector options with ratings up to IP69K for enhanced environmental protection. Its wet armature design means the working fluid surrounds the armature; however, extended energization of the coil should be monitored as it can lead to fluid degradation in some cases. Notably, cartridges configured with EPDM seals are specifically designed for systems using phosphate ester fluids and should avoid exposure to petroleum-based substances to prevent seal damage. With a maximum operating capacity of 5 gpm (20 L/min) and capable of handling pressures up to 5000 psi (350 bar), the DMDASRN912 is an efficient solution for controlling fluid direction in hydraulic systems demanding reliable performance and durability.

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.
