The Sun Hydraulics DMDATPN512 (DMDATPN512) is a solenoid-operated 3-way, 2-position cartridge valve that excels in applications requiring a direct-acting, balanced spool directional control. This model is specifically designed to handle a maximum operating pressure of 5000 psi (350 bar) and features a fatigue-rated solenoid tube assembly for robust performance in demanding environments. The valve is notable for its closed transitions between Spools B and R, enhancing performance by ensuring faster and more consistent response times, particularly useful in pilot control scenarios where capacity is less critical. The DMDATPN512 operates without the need for minimum hydraulic pressure, making it versatile across various hydraulic systems. It includes options for manual override through the D, L, or T control assemblies, with a mechanical life expectancy of around 7,000 cycles. The valve's design incorporates EPDM seals suitable for use with phosphate ester fluids; however, these seals must not be exposed to petroleum-based fluids as they can cause damage. Another key feature of this model is its wet armature design which involves the working fluid surrounding the armature\u2014important to consider if the coil remains energized over extended periods due to potential breakdowns in certain fluid types like water-glycol mixtures. For ease of maintenance and compatibility, the coils are interchangeable with other Sun Series 1 solenoid products and can be mounted in either direction on the tube. The construction of the DMDATPN512 utilizes Sun\u2019s floating style which minimizes internal parts binding caused by excessive installation torque or variations in cavity/cartridge machining. With a flow capacity of up to 12 gpm (45 L/min) and quick response times typically around 50 ms, this valve ensures efficient operation and reliability in hydraulic systems requiring precise flow control and direction.

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.
