The Sun Hydraulics DMDASAV (DMDASAV) is a solenoid-operated 3-way, 2-position cartridge valve that excels in applications requiring the management of hydraulic flow with minimal shock and vibration. This direct-acting, balanced spool directional valve incorporates a soft shift feature that significantly diminishes shock from valve actuation, making it suitable for systems where reducing mechanical stress is crucial. Although it provides smoother transitions during operation, it is not designed for tasks where precise timing control is essential; in such cases, Sun Hydraulics suggests considering their electro-proportional valves instead. The soft shift model offers a slower response time compared to Sun\u2019s standard solenoid valves, typically ranging from 150 ms to 300 ms depending on various factors such as flow rate, pressure, coil voltage, oil viscosity, and ambient temperature. It is designed to ensure consistent performance when port 1 is under positive pressure and includes options for manual override controls which are easy to install in the field but are incompatible with weatherized coils. This valve features a wet armature design where the working fluid surrounds the armature which can be susceptible to heat during prolonged energization. Special consideration should be given to fluid selection as certain fluids like water-glycol mixtures may degrade under high temperatures. The DMDASAV also benefits from an innovative magnetic design that enhances solenoid efficiency and ensures reliable valve operation even under high pressures up to 5000 psi (350 bar). The floating style construction of the valve minimizes internal binding due to installation errors or variations in cavity/cartridge machining. In summary, the DMDASAV by Sun Hydraulics offers robust performance for hydraulic systems requiring controlled flow management with reduced operational shock while providing flexible installation and maintenance options through its interchangeable cartridges and manual override functionalities.

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.
