The Sun Hydraulics DMDASBV612 (DMDASBV612) is a solenoid-operated 3-way, 2-position cartridge valve that serves as a direct-acting, balanced spool directional control valve. This model features a soft shift option designed to minimize hydraulic shock during valve actuation, though it is not suitable for applications requiring precise timing control. For those needs, Sun's electro-proportional valves would be more appropriate. The soft shift model has an increased response time ranging from 150 ms to 300 ms, which varies based on factors such as flow rate, pressure, coil voltage, oil viscosity, and ambient temperature. The DMDASBV612 valve must have port 1 under positive pressure for optimal soft shift performance and includes a push-type manual override. Notably, this manual override feature is incompatible with weatherized coils. The valve\u2019s robust construction features a solenoid tube assembly rated for up to 5000 psi (350 bar), and it incorporates EPDM seals specifically for use with phosphate ester fluids; these seals should not be exposed to petroleum-based substances. Additionally, the design includes a wet armature setup where the working fluid surrounds the armature which may affect fluid integrity over extended periods of energization. The high efficiency of the solenoid in this model ensures reliable spool actuation with high force per watt expended. The DMDASBV612 also supports various coil connector options compatible up to IP69K for enhanced environmental protection. This product utilizes Sun\u2019s floating style construction which helps prevent internal parts binding due to excessive installation torque or variations in cavity/cartridge machining. With specifications like a maximum operating pressure of 5000 psi and a flow capacity of up to 5 gpm (20 L/min), this valve is engineered for high-performance hydraulic systems requiring reliable directional control and shock minimization.

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.
