The Sun Hydraulics DMDATPN212N (DMDATPN212N) is a high-performance, solenoid-operated 3-way, 2-position cartridge valve designed for use in hydraulic systems. This direct-acting, balanced spool directional valve is capable of handling a maximum operating pressure of 5000 psi (350 bar) and has a flow capacity of up to 12 gpm (45 L/min). The valve features a unique closed transition between spools B and R, enhancing performance by providing faster and more consistent response times, particularly beneficial when used as pilot controls where capacity is less critical. The DMDATPN212N operates without the need for minimum hydraulic pressure, making it versatile for various applications. It incorporates a wet armature design allowing the working fluid to surround the armature; however, this requires consideration of the fluid type used as heat from prolonged coil energization can degrade certain fluids. Suitable for systems using phosphate ester fluids, it should not be used with petroleum-based fluids as they can damage the EPDM seals. Additionally, this model offers manual override options with detent mechanisms designed for temporary actuation and a mechanical life expectancy of about 7,000 cycles. The manual override requires a force of 5 lbs at 1000 psi on port 1 to operate. Its robust construction includes Sun\u2019s floating style design to minimize internal parts binding due to installation variances or machining errors. Interchangeable coils from Sun Series 1 solenoid products add flexibility in maintenance and repair, enhancing this valve's adaptability across different setups. This makes the DMDATPN212N an excellent choice for specialized hydraulic applications requiring reliable directional control and swift response times.

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.
