The Sun Hydraulics DMDAMNN714 (DMDAMNN714) is a high-performance, solenoid-operated 3-way, 2-position cartridge valve designed for precise control in hydraulic systems. This direct-acting, balanced spool directional valve is engineered to operate without minimum hydraulic pressure, enhancing its versatility across various applications. The valve features a robust design with a fatigue rating for 5000 psi (350 bar) service, making it suitable for high-pressure environments. Key specifications include a maximum flow capacity of 12 gpm (45 L/min) and typical response times of 50 ms for both switching on and off. The DMDAMNN714 ensures minimal leakage at high pressures, with maximum valve leakage specified at 5 in\u00b3/min at 3000 psi (80 cc/min at 210 bar). It also supports frequent operation with a switching frequency capability of up to 15,000 cycles per hour. For maintenance and manual operation, the valve comes equipped with options such as the D or L control for temporary actuation via a manual override mechanism. The mechanical life expectancy of these manual controls is approximately 7,000 cycles. Additionally, the design incorporates Sun's floating style construction to minimize internal part binding due to installation variances. The valve's wet armature design allows the working fluid to surround the armature which can be critical when considering the type of fluid used; specifically, it is compatible with EPDM seals intended for phosphate ester fluids but not suitable for petroleum-based fluids. Interchangeability of coils with other Sun Series 1 solenoid products adds flexibility in system design and maintenance. Overall, the Sun Hydraulics DMDAMNN714 offers reliable performance and durability for systems requiring precise fluid control under varying pressure conditions and frequent operational demands.

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.
