The Sun Hydraulics DMDAMPN228 (DMDAMPN228) is a solenoid-operated 3-way, 2-position cartridge valve that exemplifies precision and reliability in hydraulic system applications. This direct-acting, balanced spool directional valve is designed to operate with no minimum hydraulic pressure required, ensuring consistent performance across a range of conditions. The valve features a fatigue-rated solenoid tube assembly for services up to 5000 psi (350 bar), making it suitable for high-pressure applications. The DMDAMPN228 utilizes a closed transition between its two positions (Spools B and R), enhancing performance limits while sacrificing capacity, which is not a concern when used as pilot controls. This feature enables faster and more consistent response times, crucial for systems requiring precise control. The wet armature design of the valve ensures that the working fluid surrounds the armature, which may affect fluid properties if the coil remains energized over extended periods. This model supports interchangeable coils with other Sun Series 1 solenoid products and can be mounted in either direction on the tube. It incorporates Sun\u2019s floating style construction to minimize internal parts binding due to excessive installation torque or cavity/cartridge machining variations. With a typical response time of 50 ms and capable of handling up to 12 gpm (45 L/min), this valve is designed for robust performance and durability. Additionally, the manual override feature requires minimal force and is intended for temporary actuation only, with a mechanical life expectancy of approximately 7,000 cycles. The valve's construction also includes provisions for EPDM seals suited for phosphate ester fluids but incompatible with petroleum-based fluids which could damage the seals. Overall, the Sun Hydraulics DMDAMPN228 offers a reliable solution for managing directional control in hydraulic systems efficiently and effectively.

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.
