The Sun Hydraulics DMDASAN836 (DMDASAN836) is a high-performance solenoid-operated 3-way, 2-position cartridge valve designed for precise hydraulic control. This direct-acting, balanced spool directional valve is distinguished by its soft shift feature, which significantly reduces shock during valve actuation though it is not suitable for applications requiring critical timing control. For such needs, Sun Hydraulics recommends considering their electro-proportional valves instead. The soft shift model of the DMDASAN836 offers a slower response time compared to standard solenoid models, typically ranging from 150 ms to 300 ms depending on various factors including flow rate, pressure, coil voltage, oil viscosity, and ambient temperature. This model includes a push-type manual override control and features a solenoid tube assembly rated for fatigue at pressures up to 5000 psi (350 bar). The valve's performance and durability are further enhanced by its wet armature design and unique magnetic configuration which provides efficient solenoid operation with high spool actuating force per Watt expended. Additionally, the DMDASAN836 incorporates Sun's floating style construction which minimizes internal parts binding due to installation torque or cavity/cartridge machining variations. It is equipped with EPDM seals suitable for systems using phosphate ester fluids; however, these seals are susceptible to damage when exposed to petroleum-based fluids. With a maximum operating pressure of 5000 psi (350 bar) and a flow capacity of up to 5 gpm (20 L/min), this valve is designed for robust performance in various hydraulic applications. The manual override functionality requires an actuation force of approximately 5 lbs at 1000 psi on port 1 and features multiple 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.
