The Sun Hydraulics DMDASNV524 (DMDASNV524) is a solenoid-operated 3-way, 2-position cartridge valve designed for precision hydraulic control. This direct-acting, balanced spool directional valve features a soft shift option that mitigates shock from valve actuation, although it is not suitable for applications requiring critical timing or accurate ramping control. The soft shift model offers an increased response time compared to standard solenoids, typically ranging from 150 ms to 300 ms, dependent on various factors including flow and pressure. The DMDASNV524 operates optimally when port 1 maintains positive pressure and includes a push-type manual override control. It should be noted that other manual control options are not compatible with the soft shift feature but can be added later in the field. The valve's solenoid tube assembly is fatigue rated for up to 5000 psi (350 bar), making it robust for high-pressure applications. This model uses EPDM seals specifically designed for systems utilizing phosphate ester fluids; exposure to petroleum-based substances will damage these seals. Additionally, it incorporates a wet armature design where the working fluid surrounds the armature which could be a consideration if the coil remains energized for extended periods. The DMDASNV524 also benefits from Sun Hydraulics' floating style construction which reduces the likelihood of internal parts binding due to excessive installation torque or cavity/cartridge machining variations. With options for IP69K rated coil connectors and additional weatherized coils available, this valve ensures reliable performance even in demanding environmental conditions. The maximum operating specifications include a capacity of 5 gpm (20 L/min) and maximum operating pressure of 5000 psi (350 bar), with maximum valve leakage specified at 5 in\u00b3/min at 3000 psi (80 cc/min at 210 bar).

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.
