The Sun Hydraulics DMDADAN914 (DMDADAN914) is a solenoid-operated 3-way, 2-position cartridge valve that features a direct-acting, balanced spool directional design. This valve is particularly noted for its high-performance capabilities due to its closed transition between Spools B and R, which are closed during the shift from one position to another. This design choice enhances performance but reduces capacity, making the valve ideal for applications as pilot controls where capacity is less critical. The DMDADAN914 operates without needing a minimum hydraulic pressure, adding to its versatility in various system configurations. It includes options for manual override with a detent mechanism designed for temporary actuation, supporting mechanical life expectancy of about 7,000 cycles. The valve is compatible with EPDM seals configured for use with phosphate ester fluids; however, these seals must not be exposed to petroleum-based fluids as they can cause damage. Incorporating a wet armature design, the DMDADAN914's working fluid surrounds the armature which can be significant when the coil remains energized over extended periods\u2014particularly affecting fluids like water-glycol mixtures. The valve\u2019s coils are interchangeable with other Sun Series 1 solenoid products and can be mounted in either direction on the tube. Further enhancing its reliability and ease of installation, this model uses Sun's floating style construction that minimizes internal parts binding caused by excessive installation torque or variations in cavity/cartridge machining. With a maximum operating pressure of 5000 psi (350 bar) and a capacity of 12 gpm (45 L/min), this valve is designed to meet rigorous industrial demands while ensuring consistent and precise performance.

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.
