The Sun Hydraulics DMDAMPN828 (DMDAMPN828) is a solenoid-operated 3-way, 2-position cartridge valve that functions as a direct-acting, balanced spool directional valve. Engineered for high-performance applications, this valve features a fatigue rating for 5000 psi (350 bar) service, making it robust for demanding environments. The unique design of spools B and R which remain closed during transitions between positions enhances performance by ensuring faster and more consistent response times, particularly beneficial when used as pilot controls. This model boasts a wet armature design where the working fluid surrounds the armature. It is crucial to consider this in applications where the coil may be energized continuously as it can lead to fluid breakdown and varnish formation, potentially impacting valve functionality. The valve is designed with no minimum hydraulic pressure required for operation, thus enhancing its versatility across various hydraulic systems. Additionally, the DMDAMPN828 offers interchangeable coils with other Sun Series 1 solenoid products which can be mounted in either direction on the tube. This model also incorporates Sun's floating style construction that minimizes internal part binding due to excessive installation torque or variations in cavity/cartridge machining. It supports a maximum flow capacity of 12 gpm (45 L/min) and provides rapid response times typically around 50 ms. For maintenance or manual operation, it includes a detent mechanism in manual overrides with an expected mechanical life of about 7,000 cycles. The cartridges configured with EPDM seals are specifically designed for use with phosphate ester fluids; however, exposure to petroleum-based fluids should be avoided to prevent seal damage. This model\u2019s adaptability and robust design make it suitable for high-pressure applications requiring precise control and reliability.

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.
