The Sun Hydraulics DMDATRN512 (DMDATRN512) is a solenoid-operated, 3-way, 2-position cartridge valve designed for high-performance hydraulic systems. This direct-acting, balanced spool directional valve features a fatigue-rated solenoid tube assembly suitable for service up to 5000 psi (350 bar). It is particularly noted for its closed transition between Spools B and R, enhancing performance by ensuring faster and more consistent response times, ideal for applications where capacity is not the primary concern. The DMDATRN512 operates without requiring a minimum hydraulic pressure, making it versatile across various hydraulic applications. The manual override feature incorporated in models with D or L control uses a detent mechanism designed for temporary actuation only, with a mechanical life expectancy of around 7,000 cycles. Additionally, this model can be configured with EPDM seals specifically for use with phosphate ester fluids; however, these seals must not be exposed to petroleum-based fluids as they can cause damage. Another significant feature of the DMDATRN512 is its wet armature design which allows the working fluid to surround the armature. While this design aids in cooling, it can lead to fluid breakdown and varnish formation if the coil remains energized over extended periods. The valve also offers interchangeable coils compatible with other Sun Series 1 solenoid products and incorporates Sun's floating style construction that minimizes internal parts binding due to installation torque or machining variations. This model supports a flow capacity of up to 12 gpm (45 L/min) and has typical response times of 50 ms. With maximum operating pressures up to 5000 psi (350 bar) and switching frequencies capable of reaching up to 15,000 cycles/hr, it ensures robust performance in demanding operational conditions. The compact design includes a .75 inch (19 mm) solenoid tube diameter and weighs just .60 lb (0.30 kg), making it suitable for integration into various system configurations without significant space or weight considerations.

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.
