The Sun Hydraulics DMDATRV4E12V (Material Number: DMDATRV4E12V) is a high-performance, solenoid-operated 3-way, 2-position cartridge valve designed for precise control in hydraulic systems. This direct-acting, balanced spool directional valve is notable for its robust construction and operational efficiency. With a maximum operating pressure of 5000 psi (350 bar) and a flow capacity of up to 12 gpm (45 L/min), it is suitable for various demanding applications. The valve features a fatigue-rated solenoid tube assembly, ensuring durability under continuous high-pressure conditions. The transition between the spools B and R is closed, enhancing performance by providing faster and more consistent response times ideal for pilot control applications where capacity is less critical. Its manual override options (D, L, T control types) are designed primarily for temporary actuation with a mechanical life expectancy of about 7,000 cycles. Equipped with EPDM seals, the DMDATRV4E12V is compatible with phosphate ester fluids; however, exposure to petroleum-based fluids should be avoided to prevent seal damage. The wet armature design helps in heat management but requires consideration regarding the type of fluid used due to potential breakdown and varnish formation at higher temperatures. The valve's design incorporates interchangeable coils from Sun\u2019s Series 1 solenoid products and features a floating style construction which minimizes internal binding caused by excessive installation torque or machining variations in the cavity/cartridge interface. This makes the DMDATRV4E12V highly adaptable and easy to maintain within various system configurations.

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.
