The Sun Hydraulics DMDASRV299 (DMDASRV299) is a solenoid-operated 3-way, 2-position cartridge valve designed for high-efficiency hydraulic systems. This direct-acting, balanced spool directional valve features a unique soft shift capability, which moderates hydraulic shock during valve actuation, enhancing system longevity and reducing noise. However, it's important to note that while the soft shift feature reduces operational shock, it does not support critical timing applications; for such needs, electroproportional valves are recommended. The DMDASRV299 is designed with a wet armature setup allowing the working fluid to surround the armature. This design choice necessitates consideration of fluid type as some fluids may degrade under prolonged exposure to heat. The valve operates optimally within a flow capacity of 5 gpm/20 L/min and can withstand a maximum operating pressure of 5000 psi/350 bar. It features manual override capabilities with a push-type control but is incompatible with weatherized coils. This model incorporates Sun's floating style construction which minimizes internal part binding due to installation torque or cavity/cartridge machining variations. The solenoid tube assembly of this model is fatigue rated for demanding applications up to 5000 psi/350 bar service. Additionally, the DMDASRV299 has an IP69K rating for coil connector options ensuring robust performance in diverse environmental conditions. With its compact design weighing just 0.60 lb/0.30 kg and featuring a hex size of 7/8 in./22.2 mm, this valve is easily integrated into various hydraulic systems without requiring extensive space or complex installation procedures. Its efficient magnetic design ensures high spool actuating force per watt expended, resulting in reliable valve shifting and overall operational efficiency.

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.
