The Sun Hydraulics DNDASYV836 (DNDASYV836) is a solenoid-operated, 4-way, 2-position cartridge valve featuring a direct-acting, balanced spool design with an integrated soft shift function. This soft shift feature significantly reduces system shock during valve actuation, enhancing operational smoothness. While the soft shift cartridge can be interchanged with the standard version, it operates under lower performance limits and should not be relied upon for applications requiring precise timing or ramping control; for such needs, Sun's electro-proportional valves are recommended. The response time of this valve ranges from 150 ms to 300 ms and varies based on factors like flow rate, pressure, coil voltage, oil viscosity, and ambient temperature. For optimal performance, port 1 must maintain positive pressure. The DNDASYV836 includes a push-type manual override control; however, other manual control options cannot be factory-ordered with the soft shift feature but can be field-installed. Note that manual override is not compatible with weatherized coils. The solenoid tube assembly is designed for durability at pressures up to 5000 psi (350 bar) and incorporates a high-efficiency magnetic design for reliable operation. It employs a wet armature design where working fluid surrounds the armature\u2014an important consideration for long-term coil energization as certain fluids may degrade over time due to heat exposure. This valve uses Sun's floating style construction to reduce internal binding risks from installation torque or machining variations. It fits into cavity T-31A and has a capacity of 4 gpm (15 L/min). The maximum leakage at specified conditions is limited to 10 in\u00b3/min (160 cc/min). Additional specifications include a solenoid tube diameter of .75 in (19 mm), valve hex size of .78 in (22.2 mm), and installation torque between 30\u201335 lbf ft (41\u201347 Nm).

This solenoid-operated 4-way, 2-position cartridge is a direct-acting, balanced spool directional valve with a soft shift feature. The soft shift feature greatly reduces system shock due to valve actuation.
- 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 dependant 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.
- 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.
