The Sun Hydraulics DMDASPV812 (DMDASPV812) is a solenoid-operated 3-way, 2-position cartridge valve, designed for direct-acting, balanced spool directional control. This model features a soft shift option which aims to minimize hydraulic shock during valve actuation, although it is not suitable for applications requiring precise timing control. For such needs, Sun's electroproportional valves are recommended. The DMDASPV812 has a slower response time compared to standard solenoid cartridges from Sun Hydraulics, with typical response times ranging between 150 ms and 300 ms depending on various factors including flow rate, pressure, coil voltage, oil viscosity, and ambient temperature. It includes a push-type manual override control but is incompatible with weatherized coils when using this feature. The valve should operate under conditions where port 1 maintains positive pressure to ensure consistent performance of the soft shift feature. Constructed to handle up to 5000 psi (350 bar), the solenoid tube assembly of this model is fatigue rated for high-pressure service. It uses EPDM seals suitable for systems utilizing phosphate ester fluids; however, exposure to petroleum-based substances can damage these seals. The wet armature design means the working fluid surrounds the armature which could be a consideration if the coil remains energized for extended periods. The valve\u2019s magnetic design enhances efficiency by delivering high spool actuating force per watt expended. Additional features include an IP69K rating for coil connector options and compatibility with additional weatherized coils and kits for improved environmental protection. The DMDASPV812 also benefits from Sun's floating style construction which helps prevent internal parts binding due to excessive installation torque or machining variations in the cavity/cartridge setup.

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.
