The Sun Hydraulics DMDAMNV814 (DMDAMNV814) is a solenoid-operated 3-way, 2-position cartridge valve that features a direct-acting, balanced spool design. This model is particularly noted for its robust construction, including a solenoid tube assembly rated for fatigue at 5000 psi (350 bar), making it suitable for high-pressure applications. The valve operates with no minimum hydraulic pressure requirement, which enhances its versatility in various hydraulic systems. The DMDAMNV814 employs closed transitions between spool positions B and R, optimizing performance by ensuring faster and more consistent response times, particularly in pilot control applications where capacity is less critical. This valve also incorporates manual override options with a detent mechanism designed for temporary actuation; these are available in models equipped with D or L control options. For environments using phosphate ester fluids, cartridges with EPDM seals are recommended to prevent damage from petroleum-based substances. Additionally, the wet armature design of the valve helps in cooling but requires consideration of fluid type as certain fluids may degrade under prolonged exposure to heat. Interchangeability of coils with other Sun Series 1 solenoid products adds to the flexibility of this model, allowing for easier maintenance and part replacement. The floating style construction of the valve minimizes risks associated with internal parts binding due to installation variances or machining discrepancies. This model also supports up to 12 gpm (45 L/min) capacity and includes features like a typical response time of 50 ms and maximum operating pressures up to 5000 psi (350 bar). Overall, the Sun Hydraulics DMDAMNV814 offers a reliable solution for directing flow in high-pressure hydraulic systems while ensuring durability and operational consistency.

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.
