The Sun Hydraulics DMDALPV914 (DMDALPV914) 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 construction that includes a solenoid tube assembly rated for fatigue at 5000 psi (350 bar), making it suitable for demanding applications. The valve ensures minimal leakage and quick response times, typically around 50 ms, due to its closed transition between spool positions B and R. This model is particularly efficient in pilot control setups where capacity is less crucial but speed and consistency are vital. The DMDALPV914 operates without requiring a minimum hydraulic pressure, enhancing its versatility across various hydraulic systems. It includes options for manual override through the D or L control, which are intended for temporary actuation with a mechanical life expectancy of around 7,000 cycles. The valve's design incorporates EPDM seals configured specifically for use with phosphate ester fluids; however, these seals must be protected from petroleum-based substances to avoid damage. Its wet armature setup allows the working fluid to surround the armature which helps in heat management but requires careful consideration of fluid selection to prevent breakdown and varnish formation. Interchangeability of coils with other Sun Series 1 solenoid products adds flexibility in maintenance and replacement processes. Additionally, Sun Hydraulics' floating style construction is employed in this model to minimize internal parts binding caused by installation torque or machining variations. The DMDALPV914 supports up to 12 gpm (45 L/min) flow capacity at a maximum operating pressure of 5000 psi (350 bar), suitable for various high-pressure applications requiring reliable directional control and rapid switching capabilities.

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.
