The Sun Hydraulics DMDASRN536 (DMDASRN536) is a solenoid-operated, 3-way, 2-position cartridge valve designed for hydraulic fluid control. This direct-acting, balanced spool directional valve features a soft shift option to mitigate shock from valve actuation, although it is not suitable for applications where precise timing control is critical. The soft shift model offers a slower response time compared to standard solenoid valves, typically ranging from 150 ms to 300 ms depending on various factors such as flow rate and oil viscosity. This model includes a push-type manual override control and uses an interchangeable cartridge system that allows for easy field modifications with different manual controls. However, it's important to note that the manual override function is incompatible with weatherized coils. The DMDASRN536 operates effectively under high-pressure conditions up to 5000 psi (350 bar) and incorporates EPDM seals specifically for use with phosphate ester fluids; exposure to petroleum-based fluids can damage these seals. The valve's solenoid tube assembly is fatigue rated for robust performance in demanding environments. Additionally, the design features Sun's floating style construction which helps minimize internal part binding due to installation torque or machining variations of the cavity/cartridge. The coil connector options provide environmental protection ratings up to IP69K, ensuring durability and reliability in various operating conditions. With a maximum operating capacity of 5 gpm (20 L/min) and minimal leakage at high pressures, this valve is engineered for efficient operation in hydraulic systems requiring reliable directional control and enhanced shock absorption capabilities without compromising overall system integrity.

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.
