The Sun Hydraulics DMDAMAV914 (DMDAMAV914) is a high-performance solenoid-operated 3-way, 2-position cartridge valve designed for rigorous hydraulic control applications. This direct-acting, balanced spool directional valve is capable of operating at a maximum pressure of 5000 psi (350 bar) and has a typical response time of 50 ms. It features spools B and R which are closed during the transition between positions, enhancing performance by providing faster and more consistent response times, especially suitable for pilot controls where capacity is less critical. This model is distinguished by its robust construction that includes a wet armature design allowing the working fluid to surround the armature, which can be critical when the coil is energized for extended periods. The valve's compatibility with EPDM seals makes it ideal for systems using phosphate ester fluids, though these seals must not be exposed to petroleum-based fluids. The DMDAMAV914 also incorporates Sun's floating style construction to minimize internal parts binding caused by excessive installation torque or variations in cavity/cartridge machining. With a flow capacity of up to 12 gpm (45 L/min), this valve supports interchangeable coils with other Sun Series 1 solenoid products and can be mounted on the tube in either direction. Additionally, it features manual override options with a detent mechanism designed for temporary actuation and has an estimated mechanical life expectancy of around 7,000 cycles. The manual override requires a force of about 5 lbs at 1000 psi per port and has an override stroke of .10 inches (2.5 mm). This model weighs approximately .60 lb (0.30 kg) and requires an installation torque between 30-35 lbf.ft (41-47 Nm).

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.
