The Sun Hydraulics DMDATRV512 (DMDATRV512) is a solenoid-operated, 3-way, 2-position cartridge valve that exemplifies high-performance hydraulic control with its direct-acting, balanced spool design. This valve operates efficiently with no minimum hydraulic pressure required for functionality, making it extremely versatile in a range of applications. It features a unique closed transition between Spools B and R, optimizing performance by ensuring faster and more consistent response times ideal for pilot control systems where capacity is less critical. The DMDATRV512 is engineered to withstand demanding conditions, being fatigue rated for 5000 psi (350 bar) service. Its durability extends to the manual override mechanisms on models equipped with D or L controls, which are designed for temporary actuation and have a mechanical life expectancy of approximately 7,000 cycles. The valve\u2019s wet armature design allows the working fluid to surround the armature, a consideration when dealing with prolonged coil energization as it can lead to fluid breakdown in certain conditions. For compatibility with different system fluids, cartridges configured with EPDM seals are specifically designed for use with phosphate ester fluids; however, they must not be exposed to petroleum-based fluids which can damage the seals. Additionally, the coils of this model are interchangeable with other Sun Series 1 solenoid products and can be mounted in either direction on the tube. Furthermore, this model incorporates Sun's floating style construction which minimizes potential internal parts binding caused by excessive installation torque or machining variations in cavity/cartridge. With a switching frequency capability of up to 15,000 cycles per hour and rapid typical response times of 50 ms, the DMDATRV512 offers both reliability and high performance for sophisticated hydraulic systems.

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.
