The Sun Hydraulics DMDASBV4E12V (DMDASBV4E12V) is a solenoid-operated 3-way, 2-position cartridge valve designed for versatile hydraulic fluid direction control. This direct-acting, balanced spool valve features a soft shift option that moderates hydraulic shock during valve actuation, enhancing system longevity and reducing the risk of sudden pressure spikes. However, this soft shift design results in slower response times ranging from 150 ms to 300 ms, which may not be suitable for applications requiring precise timing or rapid ramping. The DMDASBV4E12V supports a flow capacity of up to 5 gpm (20 L/min) and can handle maximum operating pressures up to 5000 psi (350 bar). The valve is equipped with a push-type manual override control, offering an alternative operation method in scenarios where electronic control is not feasible. Notably, the manual override feature cannot be used with weatherized coils. Constructed with durability in mind, the solenoid tube assembly of the valve is fatigue rated for high-pressure applications. Additionally, the wet armature design ensures that the working fluid surrounds the armature which could lead to higher temperatures affecting fluid integrity over extended periods. Users should consider fluid compatibility carefully; cartridges configured with EPDM seals are intended for phosphate ester fluids and should avoid contact with petroleum-based substances. For environmental resilience, various coil connector options rated up to IP69K are available. The DMDASBV4E12V also incorporates Sun Hydraulics' floating style construction which minimizes internal binding risks caused by installation stresses or cavity/cartridge machining discrepancies. This model\u2019s robust build and thoughtful engineering make it a reliable choice for managing directional control in hydraulic systems across numerous applications.

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.
