The Sun Hydraulics DMDADNN514 (DMDADNN514) is a high-performance solenoid-operated 3-way, 2-position cartridge valve designed for precise hydraulic control. This direct-acting, balanced spool directional valve operates without requiring a minimum hydraulic pressure, enhancing its versatility across various applications. The valve features a fatigue-rated solenoid tube assembly capable of handling services up to 5000 psi (350 bar), making it suitable for rigorous industrial environments. Incorporating a closed transition between the spools B and R, the DMDADNN514 ensures faster and more consistent response times during operation\u2014ideal for applications where performance limit is prioritized over capacity. This characteristic particularly benefits pilot control systems where rapid and reliable actuation is critical. Additionally, the valve is equipped with manual override options (D, L, T controls) which are intended for temporary actuation with a mechanical life expectancy of about 7,000 cycles. The DMDADNN514 utilizes EPDM seals suitable for systems using phosphate ester fluids while being incompatible with petroleum-based substances which can degrade the seals. A unique feature of this model is its wet armature design; the working fluid surrounds the armature to manage heat during prolonged coil energization\u2014a factor that needs consideration in fluid selection to prevent breakdown and varnish formation. For added flexibility in installation and maintenance, the coils of this valve are interchangeable with other Sun Series 1 solenoid products and can be mounted in either direction on the tube. The construction employs Sun\u2019s floating style to minimize internal part binding caused by excessive installation torque or variations in cavity/cartridge machining. With specifications like a maximum flow capacity of 12 gpm (45 L/min) and rapid typical response time of 50 ms, this valve assures efficient operation under demanding conditions while maintaining stringent leakage control standards.

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.
