The Sun Hydraulics DMDASPN528 (DMDASPN528) is a high-performance solenoid-operated 3-way, 2-position cartridge valve. This direct-acting, balanced spool directional valve is designed for use in hydraulic systems where precise control of fluid flow is necessary. The model features a soft shift option which moderates the shift response, significantly reducing hydraulic shock and system wear. This option increases the typical response time to between 150 ms and 300 ms, depending on various factors such as flow rate, pressure, coil voltage, oil viscosity, and ambient temperature. The DMDASPN528 valve offers a maximum operating pressure of 5000 psi (350 bar) and a flow capacity of up to 5 gpm (20 L/min). It also includes a manual override feature with a push-type control mechanism, though this is not compatible with weatherized coils. The valve's construction utilizes Sun Hydraulics' floating style design which helps prevent internal parts binding due to excessive installation torque or variations in cavity/cartridge machining. This model incorporates EPDM seals suitable for systems using phosphate ester fluids; however, these seals must not be exposed to petroleum-based fluids as they will cause damage. The solenoid\u2019s wet armature design means that the working fluid surrounds the armature which can lead to fluid breakdown if the coil remains energized for extended periods. Additionally, this unit offers multiple coil connector options with ratings up to IP69K for substantial environmental protection against dust and water ingress. The robust magnetic design of the solenoid ensures high efficiency and reliable valve shifting operations by providing strong spool actuating force per watt expended. This makes the DMDASPN528 an ideal choice for applications requiring reliable and gentle directional control in hydraulic systems.

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.
