The Sun Hydraulics DMDALPN214 (DMDALPN214) is a high-performance solenoid-operated 3-way, 2-position cartridge valve designed for precise hydraulic control. This direct-acting, balanced spool directional valve operates without requiring a minimum hydraulic pressure, making it versatile for various applications. The valve features a robust design with a fatigue rating of 5000 psi (350 bar), ensuring durability and reliability under demanding conditions. The DMDALPN214 incorporates closed transitions between spools B and R, enhancing performance by providing faster and more consistent response times, especially useful in pilot control applications where capacity is less critical. It includes EPDM seals suitable for use with phosphate ester fluids; however, these seals must not be exposed to petroleum-based fluids as they can cause damage. Equipped with interchangeable coils compatible with other Sun Series 1 solenoid products, the valve offers flexibility in maintenance and setup. The coils can be mounted in either direction on the tube. Additionally, this model uses a wet armature design where the working fluid surrounds the armature, which is important to consider regarding heat generation during prolonged energization. This valve features Sun\u2019s floating style construction to minimize internal part binding due to installation torque or machining variations of cavity/cartridge. It has a mechanical life expectancy of approximately 7,000 cycles for models with D or L control manual overrides. The manual override requires minimal force and provides quick actuation for temporary operation adjustments. Specifications include a maximum operating pressure of 5000 psi (350 bar), flow capacity up to 12 gpm (45 L/min), and typical response times around 50 ms. It also supports switching frequencies up to 15000 cycles/hr, making it suitable for systems requiring frequent switching operations without compromise on performance stability.

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.
