The Sun Hydraulics DMDASBN836 (DMDASBN836) is a solenoid-operated 3-way, 2-position cartridge valve designed for use in hydraulic systems. It features a direct-acting, balanced spool directional control mechanism that provides reliable operation. The valve includes a soft shift feature which helps to mitigate system shocks caused by valve actuation, although it is not suitable for applications requiring precise timing control. For such needs, electroproportional valves are recommended. This model offers a slower response time compared to standard solenoids, typically ranging from 150 ms to 300 ms, dependent on various factors including flow rate, pressure, coil voltage, oil viscosity, and ambient temperature conditions. To ensure optimal soft shift performance, it is essential that port 1 maintains a positive pressure. The DMDASBN836 valve is equipped with a push-type manual override control and boasts a fatigue rating of 5000 psi (350 bar) for its solenoid tube assembly. It also utilizes EPDM seals suitable for phosphate ester fluids but incompatible with petroleum-based substances which can damage the seals. Additionally, the valve employs a wet armature design where the working fluid surrounds the armature; this could be significant if the coil remains energized over extended periods. The design incorporates Sun's floating style construction to minimize internal binding risks due to installation torque or machining variations of cavity/cartridge. The valve has an operational capacity of up to 5 gpm (20 L/min) and can handle maximum operating pressures up to 5000 psi (350 bar). Its manual override requires minimal force and provides precision through its controlled stroke length. The DMDASBN836 also offers various coil connector options with ratings up to IP69K for enhanced environmental protection.

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.
