The Sun Hydraulics DMDAMNV836 (DMDAMNV836) is a solenoid-operated 3-way, 2-position cartridge valve designed for high-performance hydraulic systems. This direct-acting, balanced spool directional valve is specifically engineered to handle a maximum operating pressure of 5000 psi (350 bar) and has a flow capacity of up to 12 gpm (45 L/min). The DMDAMNV836 features closed transitions between spool positions B and R, enhancing performance by providing faster and more consistent response times in applications where capacity is less critical. The construction of the DMDAMNV836 includes a wet armature design, wherein the working fluid surrounds the armature. This design consideration is crucial for applications where the valve may be continuously energized, as it helps manage the heat generated by the coil. However, it's important to note that certain fluids such as water-glycol mixtures may degrade under prolonged exposure to high temperatures, potentially affecting valve performance. This model is equipped with EPDM seals making it suitable for systems utilizing phosphate ester fluids; however, these seals must not be exposed to petroleum-based fluids which can cause damage. Additionally, the DMDAMNV836 offers flexibility in manual control options with detent mechanisms designed for temporary actuation and an expected mechanical life of approximately 7,000 cycles. For ease of integration with other hydraulic components, this valve's coils are interchangeable with other Sun Series 1 solenoid products and can be mounted in either direction on the tube. The installation is further facilitated by Sun's floating style construction which minimizes internal binding due to variations in installation torque or cavity/cartridge machining discrepancies.

This solenoid-operated 3-way, 2-position cartridge is a direct-acting, balanced spool directional valve.
- The solenoid tube assembly is fatigue rated for 5000 psi (350 bar) service.
- Spools B and R are closed in the transition between their two positions. This results in a higher performance limit at the expense of lower capacity. When used as pilot controls, where capacity is not a factor, the closed transition will provide faster and more consistent response times.
- This valve is direct actuated and requires no minimum hydraulic pressure for operation.
- On models equipped with the D or L control, the detent mechanism in the manual override is meant for temporary actuation. The D, L and T manual control assembly has a mechanical life expectancy of approximately 7,000 cycles.
- 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.
- Coils are interchangeable with other Sun Series 1 solenoid products and can be mounted on the tube in either direction.
- 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.
