The Sun Hydraulics DMDASRN736 (DMDASRN736) is a solenoid-operated, 3-way, 2-position cartridge valve designed for precise hydraulic fluid direction in various applications. This direct-acting, balanced spool directional valve features a unique soft shift control that moderates the shock typically associated with valve actuation, enhancing system longevity and reducing wear. However, it is crucial to note that while this soft shift feature diminishes operational shock, it is not suitable for applications requiring critical timing or exact ramping control. For such needs, electroproportional valves are recommended. This model incorporates a push-type manual override and boasts compatibility with twist-lock manual overrides, although it should be noted that these are not compatible with weatherized coils. The valve\u2019s solenoid tube assembly is fatigue rated for up to 5000 psi (350 bar), ensuring robust performance under high-pressure conditions. The wet armature design used in this valve means the coil's heat directly affects the working fluid, which could impact fluid integrity over extended periods. In terms of environmental resilience, the DMDASRN736 offers multiple coil connector options with protection ratings up to IP69K and additional weatherized coils for enhanced environmental shielding. It also features Sun\u2019s floating style construction which minimizes internal parts binding due to installation torque or machining variations in the cavity/cartridge. Designed for a maximum flow capacity of 5 gpm (20 L/min) and a maximum operating pressure of 5000 psi (350 bar), this model ensures minimal leakage and efficient performance across various hydraulic systems. Its compact design includes a manual override feature requiring minimal force and offers straightforward field installation options for different manual controls excluding those combined with soft shift features.

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.
