The Sun Hydraulics DMDALRN211 (DMDALRN211) is a high-performance solenoid-operated 3-way, 2-position cartridge valve designed for precise hydraulic control. This direct-acting, balanced spool directional valve features a robust design with a fatigue rating of 5000 psi (350 bar), making it suitable for demanding applications. The valve\u2019s spools, B and R, are closed during the transition between positions, enhancing performance by ensuring faster and more consistent response times, particularly beneficial when used as pilot controls. This model is directly actuated and functions without requiring a minimum hydraulic pressure, which simplifies system design and increases reliability. It also includes manual override options with the D or L control featuring a detent mechanism designed for temporary actuation. With an expected mechanical life of approximately 7,000 cycles for the manual control assembly, this valve promises durability and long-term performance. The DMDALRN211 is equipped with EPDM seals appropriate for systems using phosphate ester fluids; however, these seals must not be exposed to petroleum-based fluids as they can cause damage. Its wet armature design allows the working fluid to surround the armature which helps manage heat during prolonged coil energization but requires careful consideration of fluid selection to prevent breakdowns. Interchangeability of coils with other Sun Series 1 solenoid products adds versatility to this model, allowing coils to be mounted in either direction on the tube. Furthermore, its construction incorporates Sun\u2019s floating style design that minimizes internal parts binding due to installation torque or cavity/cartridge machining variations. This feature ensures reliable operation and ease of installation across various hydraulic setups. With capabilities like a maximum flow capacity of 12 gpm (45 L/min) and rapid response time typically around 50 ms, the Sun Hydraulics DMDALRN211 valve is an excellent choice for advanced hydraulic systems requiring efficient directional control.

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.
