The Sun Hydraulics DMDASBN936 (DMDASBN936) is a solenoid-operated 3-way, 2-position cartridge valve designed for hydraulic control applications requiring directional control and soft shift operation. This direct-acting, balanced spool valve features a unique soft shift mechanism that moderates the speed of actuation to reduce hydraulic shock, enhancing system longevity and stability. Although it offers smoother transitions compared to standard solenoids, its slower response time of 150 ms to 300 ms may not be suitable for applications demanding precise timing or rapid actuation. The DMDASBN936 is engineered with a push-type manual override control and incorporates Sun Hydraulics' floating style construction which minimizes internal parts binding due to installation torque variations or cavity/cartridge machining discrepancies. The valve operates optimally under a maximum pressure of 5000 psi (350 bar) and has a flow capacity of up to 5 gpm (20 L/min). Its solenoid tube assembly is fatigue rated for high-pressure service, ensuring durability and reliability in demanding environments. Designed with environmental adaptability in mind, the DMDASBN936 can be fitted with weatherized coils and offers coil connector options rated up to IP69K for superior protection against harsh conditions. The valve also utilizes a wet armature design where the working fluid surrounds the armature; this design consideration is crucial as prolonged energization could lead to fluid degradation in certain conditions. This model uses EPDM seals specifically for systems utilizing phosphate ester fluids; exposure to petroleum-based substances can damage these seals. With its efficient magnetic design, the solenoid provides high spool actuating force per watt expended, leading to reliable shifting performance essential for various hydraulic applications.

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.
