The Sun Hydraulics DNDASHV836 (DNDASHV836) is a solenoid-operated, 4-way, 2-position cartridge valve designed for precise directional control in hydraulic systems. Featuring a direct-acting, balanced spool with a soft shift capability, this valve minimizes system shock during actuation. Although the soft shift feature reduces performance limits compared to standard cartridges and increases response time\u2014ranging from 150 ms to 300 ms\u2014it provides smoother transitions which can be beneficial in non-critical timing applications. For applications necessitating accurate ramping or timing control, electroproportional valves are recommended. The DNDASHV836 includes a push-type manual override for operational flexibility; however, this feature is incompatible with weatherized coils. It operates with a maximum pressure of 5000 psi (350 bar) and has a capacity of 4 gpm (15 L/min). The valve's fatigue-rated solenoid tube assembly ensures durability under high-pressure conditions, while the wet armature design enhances solenoid efficiency by using the working fluid for cooling. This design consideration is crucial if the coil remains energized over extended periods. Additional features include IP69K-rated coil connector options for enhanced environmental protection and Sun's floating style construction to prevent internal binding due to installation or machining variances. The valve requires an installation torque of 30-35 lbf ft (41-47 Nm) and weighs approximately 0.60 lb (0.30 kg). With its high-efficiency magnetic design yielding significant spool actuating force per watt expended, the DNDASHV836 ensures reliable shifting performance across various hydraulic applications.

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.
