The Sun Hydraulics DMDATNV2E12V (DMDATNV2E12V) is a high-performance, solenoid-operated 3-way, 2-position cartridge valve designed for precise fluid control in hydraulic systems. This direct-acting, balanced spool directional valve features a robust design that can handle maximum operating pressures up to 5000 psi (350 bar) and has a flow capacity of 12 gpm (45 L/min). The valve is particularly noted for its closed transitions between spools B and R, enhancing performance by ensuring faster and more consistent response times, ideal for applications where rapid actuation is critical. The DMDATNV2E12V incorporates a wet armature design allowing the working fluid to surround the armature, which is beneficial for heat dissipation but requires careful consideration of the fluid type to avoid breakdowns or varnishing at elevated temperatures. Suitable for use with phosphate ester fluids when configured with EPDM seals, this valve is versatile but must not be exposed to petroleum-based fluids which could damage the seals. Additional features include interchangeable coils with other Sun Series 1 solenoid products, manual override options with a mechanical life expectancy around 7,000 cycles, and a floating style construction that minimizes internal parts binding. This makes it an excellent choice for systems requiring reliable and durable components with minimal maintenance needs. The compact design also ensures easy installation with specific torque requirements ensuring secure fitting without damaging the valve or system.

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.
