The Sun Hydraulics DMDASAV298 (DMDASAV298) is a solenoid-operated 3-way, 2-position cartridge valve, designed as a direct-acting, balanced spool directional control valve. It features a unique soft shift capability that moderates hydraulic shock during valve actuation, making it suitable for applications where reduced shock is preferred, though it is not ideal for situations requiring precise timing or ramping control. This model has been engineered to provide slower response times ranging from 150 ms to 300 ms depending on various factors including flow, pressure, coil voltage, oil viscosity, and ambient temperature. The DMDASAV298 valve supports a maximum operating pressure of up to 5000 psi (350 bar) and has a flow capacity of up to 5 gpm (20 L/min). It incorporates EPDM seals which are specifically used with phosphate ester fluids; however, these seals are susceptible to damage if exposed to petroleum-based fluids. The design includes a wet armature setup where the working fluid surrounds the armature which may affect performance if the coil remains energized over extended periods. This model also includes a push-type manual override and boasts an installation torque of 30 - 35 lbf ft (41 - 47 Nm). The manual override feature is not compatible with weatherized coils but provides flexibility in control during system maintenance or emergency conditions. Additionally, the solenoid tube assembly of this model is fatigue rated for high-pressure durability. For environmental adaptability, the DMDASAV298 offers coil connector options with ratings up to IP69K and additional weatherized coils are available for enhanced protection against harsh conditions. Lastly, its construction utilizes Sun\u2019s floating style design which minimizes internal part binding due to installation torque variations or cavity/cartridge machining discrepancies. This model's robust magnetic design ensures efficient operation with high spool actuating force per watt expended.

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.
