The Sun Hydraulics DMDATBV212N (DMDATBV212N) 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 features a robust design with a fatigue-rated solenoid tube assembly for up to 5000 psi (350 bar) service. It offers minimal internal leakage at high pressures, maintaining an efficient operation with maximum valve leakage at 110 SUS (24 cSt) being only 5 in\u00b3/min at 3000 psi (80 cc/min at 210 bar). The valve's spools B and R are closed during the transition between positions, which enhances performance by providing faster and more consistent response times, especially suitable for applications requiring precise control such as in pilot operations where capacity is less critical. The DMDATBV212N operates without minimum hydraulic pressure and incorporates a wet armature design where the working fluid surrounds the armature, necessitating consideration of fluid characteristics due to heat exposure from prolonged coil energization. Equipped with interchangeable coils compatible with other Sun Series 1 solenoid products and featuring a floating style construction, this valve minimizes potential internal part binding caused by excessive installation torque or cavity/cartridge machining variations. Additional specifications include a flow capacity of 12 gpm (45 L/min), typical response time of 50 ms, and manual override options that are intended for temporary actuation with a mechanical life expectancy of approximately 7,000 cycles. This model is also available with EPDM seals specifically for use with phosphate ester fluids; however, these seals must not be exposed to petroleum-based fluids as they will degrade. The DMDATBV212N is versatile enough to be mounted on the tube in either direction and ensures reliable performance across various hydraulic applications.

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.
