The Sun Hydraulics DMDASRN71299 (DMDASRN71299) is a high-performance, solenoid-operated 3-way, 2-position cartridge valve designed for hydraulic applications requiring reliable directional control. This direct-acting, balanced spool valve features a unique soft shift functionality that moderates the shock typically associated with valve actuation, although it is not suitable for applications where precise timing control is critical. The valve's response time varies between 150 ms to 300 ms depending on several factors including flow rate, pressure, coil voltage, oil viscosity, and ambient temperature conditions. Equipped with a manual override in a push-type configuration, the DMDASRN71299 facilitates easy field adjustments. However, it's important to note that certain manual control options are incompatible with the soft shift feature but can be installed separately. The unit's solenoid tube assembly is rated for fatigue at pressures up to 5000 psi (350 bar), ensuring durability under high-pressure operations. Designed with Sun Hydraulics' floating style construction, the DMDASRN71299 minimizes internal part binding which could result from excessive installation torque or variations in cavity/cartridge machining. Additionally, its wet armature design means the working fluid surrounds the armature which may affect fluid integrity over extended periods of energization. This valve also incorporates EPDM seals specifically for use with phosphate ester fluids; exposure to petroleum-based fluids should be avoided as it can damage these seals. For environmental resilience and operational reliability in diverse conditions, various coil connector options rated up to IP69K are available along with weatherized coils and kits for enhanced protection against elements. This versatile cartridge valve supports up to 5 gpm (20 L/min) capacity at a maximum operating pressure of 5000 psi (350 bar), making it an ideal choice for a range of hydraulic applications requiring robust performance and gentle operational characteristics.

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.
