The Sun Hydraulics DMDADRN212 (DMDADRN212) is a solenoid-operated 3-way, 2-position cartridge valve that features a direct-acting, balanced spool directional design. This valve is particularly noted for its robust construction and is fatigue rated for 5000 psi (350 bar) service, ensuring reliable performance under high-pressure conditions. The DMDADRN212 operates with no minimum hydraulic pressure required, making it versatile for various applications. The valve's spools (B and R) are closed during the transition between the two positions to enhance performance limits at the cost of lower capacity. However, this feature contributes to faster and more consistent response times when used as pilot controls. This model also includes manual override options with detent mechanisms designed for temporary actuation; these are estimated to withstand approximately 7,000 cycles. Designed with EPDM seals, the DMDADRN212 is suitable for systems using phosphate ester fluids but should avoid contact with petroleum-based fluids which can damage the seals. The wet armature design of this valve ensures that the working fluid surrounds the armature, which is critical in maintaining temperature control when the coil is energized over extended periods. This valve supports a maximum flow capacity of 12 gpm (45 L/min) and features interchangeable coils compatible with other Sun Series 1 solenoid products. The construction incorporates Sun's floating style design to minimize internal parts binding caused by excessive installation torque or machining variations in cavity/cartridge. With a typical response time of 50 ms and capable of handling up to 15,000 switching cycles per hour, the Sun Hydraulics DMDADRN212 offers a reliable solution for controlled fluid management in 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.
