The Sun Hydraulics DMDAMPN612N (DMDAMPN612N) is a high-performance, solenoid-operated 3-way, 2-position cartridge valve. This direct-acting, balanced spool directional valve is engineered for precision and reliability in hydraulic systems. Featuring a fatigue rating for 5000 psi (350 bar) service, the valve is particularly suited for applications requiring robust performance under high pressure conditions. The spool transitions in this valve are closed, enhancing performance by providing faster and more consistent response times, ideal for use as pilot controls where capacity is less critical. The DMDAMPN612N operates without needing a minimum hydraulic pressure, adding to its versatility and ease of integration into various hydraulic circuits. Optional manual override controls (D or L control types) come with a detent mechanism designed for temporary actuation, with a mechanical life expectancy of around 7,000 cycles. The EPDM seals option makes it suitable for systems using phosphate ester fluids while avoiding contact with petroleum-based fluids to prevent seal damage. This model also incorporates a wet armature design which keeps the working fluid in direct contact with the armature that can be vulnerable to heat during prolonged energization \u2014 an important consideration when using certain fluid types like water-glycol mixtures. Additionally, its coils are interchangeable with other Sun Series 1 solenoid products and can be mounted in either direction on the tube. Sun Hydraulics has designed the DMDAMPN612N with their floating style construction to minimize internal parts binding due to installation torque or machining variations in cavity-cartridge setups. This design feature ensures reliable operation and longevity of the valve even under challenging installation conditions.

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.
