The Sun Hydraulics DMDASNV724 (DMDASNV724) is a solenoid-operated 3-way, 2-position cartridge valve featuring a direct-acting, balanced spool design. This model includes a soft shift feature that moderates hydraulic shock during valve actuation, making it suitable for applications sensitive to sudden changes in pressure but not ideal for scenarios requiring precise timing control. The valve's performance is characterized by a response time ranging from 150 ms to 300 ms, influenced by factors such as flow rate, pressure, coil voltage, oil viscosity, and ambient temperature. Designed with versatility in mind, the DMDASNV724 incorporates a push-type manual override control and offers various manual control configurations that can be adapted post-installation. It is built to endure up to 5000 psi (350 bar) of operational pressure with its fatigue-rated solenoid tube assembly. Special attention is needed regarding the valve\u2019s EPDM seals which are compatible only with phosphate ester fluids; exposure to petroleum-based substances can lead to seal degradation. Moreover, the valve adopts a wet armature design where the working fluid envelops the armature. This aspect is crucial as prolonged energization of the coil could elevate fluid temperatures and degrade certain fluid types. The efficient magnetic design of the solenoid ensures high actuating force per watt expended, enhancing reliable spool shifting. Additional features include an IP69K rating for coil connector options which underscores its robustness against environmental factors. The floating style construction of this model minimizes internal binding risks caused by installation errors or cavity/cartridge machining variations. With specifications like a maximum operating capacity of 5 gpm (20 L/min) and maximum leakage at 3000 psi set at 5 in\u00b3/min (80 cc/min), this valve is engineered for high performance and reliability in demanding hydraulic systems.

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.
