The Sun Hydraulics DMDASRV712N (DMDASRV712N) is a solenoid-operated, 3-way, 2-position cartridge valve designed for precise hydraulic control. Featuring a direct-acting, balanced spool design, this valve allows for the effective direction of flow within hydraulic systems. The DMDASRV712N includes a soft shift feature which moderates the speed and pressure changes associated with valve actuation, thereby minimizing hydraulic shock. This is particularly beneficial in applications sensitive to sudden shifts in pressure and flow. This model is engineered with a wet armature design where the working fluid surrounds the armature which can be significant in applications where the coil remains energized for extended periods. The heat generated by the coil may affect fluid properties over time, especially in water-glycol mixtures that are prone to breakdown and varnish formation at elevated temperatures. The valve's magnetic design enhances efficiency, ensuring high spool actuating force per watt of power expended, which translates to reliable shifting performance. The DMDASRV712N is built to accommodate up to 5 gpm (20 L/min) flow capacity and can withstand a maximum operating pressure of 5000 psi (350 bar). It features manual override capabilities with a push-type control and has various coil connector options rated up to IP69K for substantial environmental resistance. The cartridge is also compatible with EPDM seals suitable for phosphate ester fluids but should not be exposed to petroleum-based fluids. Furthermore, Sun Hydraulics' floating style construction incorporated into this model minimizes internal parts binding which could result from excessive installation torque or variations in cavity/cartridge machining. This ensures consistent performance and durability even under challenging operational conditions. Overall, the DMDASRV712N offers robust control capabilities suited for diverse hydraulic applications where reliability and precision are crucial.

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.
