The Sun Hydraulics DMDAMRN211 (DMDAMRN211) is a high-performance solenoid-operated 3-way, 2-position cartridge valve, designed for direct-acting and balanced spool directional control. This model is distinct for its closed transitions between Spools B and R, enhancing performance by ensuring faster and more consistent response times, particularly suitable for pilot control applications where capacity is less critical. The valve does not require a minimum hydraulic pressure to operate, making it versatile across various hydraulic systems. The robust construction of the DMDAMRN211 includes a fatigue-rated solenoid tube assembly capable of handling pressures up to 5000 psi (350 bar), making it ideal for rigorous industrial applications. It features interchangeable coils with other Sun Series 1 solenoid products, allowing flexibility in maintenance and system upgrades. The valve\u2019s wet armature design helps in heat management but requires consideration regarding the type of fluid used to avoid breakdowns from prolonged exposure to high temperatures. Additionally, this model incorporates Sun\u2019s floating style construction which minimizes internal parts binding\u2014a common issue due to excessive installation torque or cavity/cartridge machining variations. With a maximum flow capacity of 12 gpm (45 L/min) and quick response times typically around 50 ms, the DMDAMRN211 is designed for efficient performance in controlling fluid direction in hydraulic systems. It supports manual override functions but is recommended mainly for temporary actuation due to the mechanical life expectancy of approximately 7,000 cycles. Overall, the Sun Hydraulics DMDAMRN211 offers a reliable solution for directional control in complex hydraulic systems requiring high pressure and rapid response capabilities without necessitating minimum operating pressure conditions.

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.
