The Sun Hydraulics DMDAMAV228 (DMDAMAV228) is a high-performance, solenoid-operated 3-way, 2-position cartridge valve. This direct-acting, balanced spool directional valve is specifically designed to handle a maximum operating pressure of 5000 psi (350 bar) and has a flow capacity of 12 gpm (45 L/min). It features a fatigue-rated solenoid tube assembly suitable for intensive service conditions. The valve's design includes closed transitions between spools B and R, optimizing performance by ensuring faster and more consistent response times especially in applications where capacity is less critical. The DMDAMAV228 operates without requiring a minimum hydraulic pressure, making it versatile for various hydraulic systems. It includes manual override options with detent mechanisms designed for temporary actuation, supporting around 7,000 cycles mechanically. Notably, this model uses EPDM seals suited for systems utilizing phosphate ester fluids; however, these seals are vulnerable to damage when exposed to petroleum-based substances. Furthermore, the valve incorporates a wet armature design which keeps the armature surrounded by working fluid that can absorb heat from the coil\u2014important in scenarios where the coil remains energized over extended periods. The interchangeable coils compatible with other Sun Series 1 solenoid products add to its flexibility in installation and maintenance. Another feature is its floating style construction which minimizes potential internal binding due to variances in installation torque or machining. Additionally equipped with features like a typical response time of 50 ms and maximum leakage at 3000 psi rated at 5 in\u00b3/min., this valve is engineered for reliability and efficiency in demanding applications. The manual override requires minimal force and has a stroke length adequate for effective temporary control, ensuring operational ease under varied pressure settings.

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.
