The Sun Hydraulics DMDADPV228 (DMDADPV228) is a high-performance solenoid-operated 3-way, 2-position cartridge valve designed for robust hydraulic applications. It features a direct-acting, balanced spool with closed transitions between positions B and R, enhancing performance by providing faster and more consistent response times, particularly suitable for pilot control applications where capacity is less critical. The valve operates without the need for minimum hydraulic pressure, making it versatile in various operational contexts. With a maximum operating pressure of 5000 psi (350 bar) and a flow capacity of up to 12 gpm (45 L/min), the DMDADPV228 is built to handle demanding tasks. The valve's response time is typically around 50 ms, ensuring quick action in system operations. Designed with interchangeable coils that fit other Sun Series 1 solenoid products and can be mounted in either direction on the tube, this model offers flexibility in installation and maintenance. The construction incorporates Sun's floating style design to minimize internal part binding due to excessive installation torque or variations in cavity/cartridge machining. The manual override feature requires a force of about 5 lbs at 1000 psi (133 N at 100 bar) for activation, with a stroke distance of .10 inches (2.5 mm). Additionally, the valve's solenoid tube assembly is fatigue-rated for long-term durability under high-pressure conditions. For systems using phosphate ester fluids, cartridges configured with EPDM seals are recommended; however, these should not be exposed to petroleum-based fluids as they can damage the seals. The wet armature design surrounds the armature with working fluid which can affect fluid integrity if exposed to prolonged heat from coil energization. Overall, the Sun Hydraulics DMDADPV228 provides reliable performance and flexibility for hydraulic systems requiring precise control and rapid response under varying operational conditions.

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.
