The Sun Hydraulics DMDAMNV628 (DMDAMNV628) is a solenoid-operated 3-way, 2-position cartridge valve designed for high-performance hydraulic systems. This direct-acting, balanced spool directional valve is particularly noted for its robust construction including a solenoid tube assembly rated for fatigue at 5000 psi (350 bar), making it suitable for demanding applications. The valve features closed transitions between Spools B and R, optimizing performance by allowing faster and more consistent response times ideal for pilot control applications where capacity is less critical. The DMDAMNV628 operates without requiring a minimum hydraulic pressure, enhancing its versatility in various system configurations. It includes options for manual overrides with detent mechanisms designed for temporary actuation, boasting a mechanical life expectancy of around 7,000 cycles. Special attention is given to the compatibility of seal materials; models with EPDM seals are specifically configured for use with phosphate ester fluids, avoiding damage that could be caused by exposure to petroleum-based substances. This model also employs a wet armature design where the working fluid surrounds the armature, which can be significant in scenarios where the coil remains energized over extended periods\u2014potentially affecting fluid integrity due to heat exposure. The interchangeable coils compatible with other Sun Series 1 solenoid products offer flexibility in maintenance and replacement procedures. Furthermore, its construction incorporates Sun\u2019s floating style design to minimize internal parts binding which could occur due to variations in installation torque or machining discrepancies. Key specifications include a flow capacity of 12 gpm (45 L/min), maximum operating pressure of 5000 psi (350 bar), typical response time of 50 ms, and maximum valve leakage at 3000 psi set at approximately 5 in\u00b3/min. The valve's physical attributes include a solenoid tube diameter of .75 inches (19 mm) and hex size of .875 inches (22.2 mm), with an installation torque requirement between 30-35 lbf\u00b7ft (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.
