The Sun Hydraulics DMDADAV814N (DMDADAV814N) is a high-performance solenoid-operated 3-way, 2-position cartridge valve designed for precise hydraulic control. This direct-acting, balanced spool directional valve features a robust design with a fatigue rating of 5000 psi (350 bar), making it suitable for demanding applications. The valve operates without requiring a minimum hydraulic pressure, enhancing its versatility across various hydraulic systems. Equipped with B and R spools that are closed during the transition between two positions, the DMDADAV814N offers superior performance by providing faster and more consistent response times, especially useful in pilot control applications where capacity is less critical. The manual override in models with D or L control has a detent mechanism intended for temporary actuation and boasts a mechanical life expectancy of approximately 7,000 cycles. For environments using phosphate ester fluids, cartridges configured with EPDM seals are recommended to prevent damage from petroleum-based substances. Additionally, the valve's wet armature design allows the working fluid to surround the armature, which could be relevant when considering fluid type and operating durations due to potential heat exposure effects on fluid integrity. This model incorporates Sun\u2019s floating style construction to minimize internal parts binding caused by excessive installation torque or cavity/cartridge machining variations. It also supports interchangeable coils with other Sun Series 1 solenoid products for enhanced flexibility in system design. Key specifications include a flow capacity of 12 gpm (45 L/min), typical response time of 50 ms, and maximum operating pressure of 5000 psi (350 bar). The DMDADAV814N is an efficient solution for systems requiring reliable switching capabilities and precise directional control in hydraulic circuits.

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.
