The Sun Hydraulics DMDASRN948 (DMDASRN948) is a solenoid-operated 3-way, 2-position cartridge valve designed for efficient directional control in hydraulic systems. This direct-acting, balanced spool valve features a unique soft shift functionality that significantly reduces shock from valve actuation, making it suitable for applications sensitive to sudden changes in pressure or flow. However, it is not recommended for use where precise timing control is critical, such as applications requiring accurate ramping. The DMDASRN948 model offers a response time ranging between 150 ms to 300 ms, depending on various factors including flow rate, pressure, coil voltage, oil viscosity, and ambient temperature. It is essential that port 1 maintains positive pressure to ensure consistent performance of the soft shift feature. The valve includes a push-type manual override control but is incompatible with other manual controls when configured with soft shift. This model also boasts a durable solenoid tube assembly rated for up to 5000 psi (350 bar), and it utilizes EPDM seals suitable for systems using phosphate ester fluids; these seals are vulnerable to damage if exposed to petroleum-based fluids. The wet armature design means the working fluid surrounds the armature which can be an issue if the coil remains energized over long periods as heat build-up can degrade certain fluid types. With a maximum operating capacity of 5 gpm (20 L/min) and maximum operating pressure of 5000 psi (350 bar), the DMDASRN948 also features weatherproof coil connector options up to IP69K for enhanced environmental protection. Its floating style construction minimizes internal part binding due to installation torque or machining variations in the cavity/cartridge setup. This model's robust design and versatile features make it an excellent choice for various hydraulic applications requiring reliable valve operation with moderate flow handling capabilities.

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.
