The Sun Hydraulics DMDALNV214N (DMDALNV214N) is a solenoid-operated 3-way, 2-position cartridge valve engineered for high-performance hydraulic systems. This direct-acting, balanced spool directional valve is specifically designed with features that enhance its operational efficiency and reliability. The valve operates with a maximum capacity of 12 gpm (45 L/min) and can withstand a maximum operating pressure of 5000 psi (350 bar), making it suitable for robust applications. A notable feature of the DMDALNV214N is its closed transition between Spools B and R, optimizing performance by ensuring faster and more consistent response times during operation. This makes the valve particularly effective when used as pilot controls where capacity is less critical. Additionally, the valve's design incorporates a wet armature setup, where the working fluid surrounds the armature. This configuration helps in heat management but requires careful consideration of fluid characteristics to prevent breakdowns or varnish formation. The solenoid tube assembly of this model is fatigue-rated for high-pressure service, enhancing its durability and lifespan under challenging conditions. Furthermore, for manual override situations, the valve includes a detent mechanism designed for temporary actuation with an estimated mechanical life expectancy of about 7,000 cycles. For compatibility with different system fluids, cartridges configured with EPDM seals are recommended exclusively for systems using phosphate ester fluids. The interchangeable coils feature across Sun Series 1 solenoid products allow flexibility in maintenance and replacement processes. Overall, the Sun Hydraulics DMDALNV214N offers precise control in hydraulic systems requiring high pressure handling capabilities combined with reliable switching performance. Its robust construction and thoughtful design features make it an essential component for specialized hydraulic applications requiring meticulous flow direction control.

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.
