The Sun Hydraulics DMDASPV836 (DMDASPV836) is a solenoid-operated 3-way, 2-position cartridge valve designed for precise hydraulic fluid direction control. This direct-acting, balanced spool valve incorporates a soft shift feature that minimizes hydraulic shock during valve actuation, enhancing system longevity and reducing potential damage to hydraulic components. Although the soft shift model offers a slower response time\u2014typically between 150 ms to 300 ms\u2014it is not suitable for applications where timing is critical, such as those requiring accurate ramping or timing control. With a maximum operating pressure of 5000 psi (350 bar) and a flow capacity of up to 5 gpm (20 L/min), the DMDASPV836 is robust enough for demanding applications. The valve's manual override feature comes with a push-type control, allowing for manual operation when necessary; however, it should be noted that this functionality is incompatible with weatherized coils. The solenoid tube assembly of this model is fatigue rated for high-pressure service, ensuring reliability and performance durability. The valve features EPDM seals which are specifically designed for use with phosphate ester fluids; exposure to petroleum-based fluids can damage these seals. Additionally, its wet armature design means that the working fluid surrounds the armature which could be susceptible to heat during prolonged coil energization\u2014a factor to consider in system design and maintenance. For environmental protection in challenging conditions, additional weatherized coils and kits are available. The construction of the DMDASPV836 includes Sun's floating style design which helps prevent internal parts binding due to installation torque or machining variations in the cavity/cartridge setup. This model also provides various coil connector options with ratings up to IP69K for enhanced protection against ingress of dust and high-temperature water jets.

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.
