The Sun Hydraulics DMDAMNN836 (DMDAMNN836) is a high-performance solenoid-operated 3-way, 2-position cartridge valve designed for robust industrial applications. This direct-acting, balanced spool directional valve is 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 valve features closed transitions between Spools B and R, optimizing performance by providing faster and more consistent response times in pilot control applications where capacity is less critical. The DMDAMNN836 utilizes a wet armature design, ensuring that the working fluid surrounds the armature which may be significant when the coil is energized for extended periods. It is important to note that this design can influence fluid integrity under prolonged exposure to heat. The valve\u2019s manual override option includes a detent mechanism designed for temporary actuation with an expected mechanical life of around 7,000 cycles. Additionally, the cartridges configured with EPDM seals are specifically intended for use with phosphate ester fluids; exposure to petroleum-based fluids can damage these seals. The interchangeability of coils with other Sun Series 1 solenoid products adds versatility, allowing for adjustments in mounting orientation according to system requirements. This model also incorporates Sun\u2019s floating style construction which minimizes internal part binding risks caused by excessive installation torque or variances in cavity/cartridge machining. With its robust design and flexible features, the Sun Hydraulics DMDAMNN836 valve is suited for various demanding applications requiring reliable directional control and rapid response times.

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.
