The Sun Hydraulics DMDASBV814N (DMDASBV814N) is a solenoid-operated 3-way, 2-position cartridge valve. This direct-acting, balanced spool directional valve is designed for use in hydraulic systems requiring reliable control of fluid flow direction. With a maximum operating pressure of 5000 psi (350 bar) and a flow capacity of 5 gpm (20 L/min), it is capable of handling moderate flow rates under high-pressure conditions. The DMDASBV814N features a soft shift option which moderates the transition of valve states, thereby reducing system shocks caused by rapid actuation. This feature increases the response time to between 150 ms and 300 ms, dependent on various factors including flow rate and oil viscosity. Although this may not be suitable for applications where precise timing control is critical, it offers significant benefits in reducing wear and tear on mechanical components due to smoother operation. Additionally, this model includes a push-type manual override control, providing an alternative means of operation in the event of power failure or when electrical control is not feasible. The manual override function requires a force of approximately 5 lbs at 1000 psi per port to operate, with a stroke length of .10 inches. The valve's construction incorporates Sun\u2019s floating style design which minimizes internal binding risks that can occur due to excessive installation torque or variations in cavity/cartridge machining. The solenoid tube assembly within this model is fatigue rated for robust performance even under continuous high-pressure conditions. For environmental resilience, the DMDASBV814N offers options for weatherized coils and has coil connector options rated up to IP69K for enhanced protection against dust and moisture ingress. This makes the valve suitable for harsh operating environments where reliability and longevity are critical.

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.
