The Sun Hydraulics DMDALNV214 (DMDALNV214) is a solenoid-operated 3-way, 2-position cartridge valve designed for precise hydraulic control. This direct-acting, balanced spool directional valve is notable for its robust construction and high performance capabilities. The valve operates without requiring a minimum hydraulic pressure, making it versatile for various applications. It features a solenoid tube assembly that is fatigue rated for 5000 psi (350 bar) service, ensuring durability even under extreme conditions. The DMDALNV214 offers closed transitions between Spools B and R, enhancing performance by providing faster and more consistent response times especially in pilot control applications where capacity is less critical. The manual override incorporated into the valve has a detent mechanism designed for temporary actuation with a mechanical life expectancy of around 7,000 cycles. Configurations with EPDM seals are specifically tailored for systems using phosphate ester fluids; however, exposure to petroleum-based fluids should be avoided as it may damage the seals. Additionally, the wet armature design of the valve ensures that the working fluid surrounds the armature which can be crucial when the coil is energized over long periods. This model also supports interchangeable coils with other Sun Series 1 solenoid products and can be mounted in either direction on the tube. It incorporates Sun's floating style construction to minimize internal parts binding due to 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 engineered to meet rigorous industrial demands while maintaining precise control and reliability in hydraulic systems.

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.
