The Sun Hydraulics DMDALBN211 (DMDALBN211) 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 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 robust design with a fatigue-rated solenoid tube assembly suitable for demanding applications. The DMDALBN211 incorporates advanced features such as closed transitions between spools B and R, enhancing performance by providing faster and more consistent response times, especially suitable for pilot control applications where capacity is less critical. Additionally, the valve operates without requiring a minimum hydraulic pressure, adding to its versatility in various system configurations. This model is equipped with EPDM seals specifically for use with phosphate ester fluids; however, it should not be exposed to petroleum-based fluids as they can damage the seals. The wet armature design of the valve ensures that the working fluid surrounds the armature which might require considerations regarding fluid type and operational durations due to potential heat generation. Interchangeability of coils with other Sun Series 1 solenoid products offers flexibility in maintenance and upgrades. Moreover, the floating style construction minimizes internal parts binding risks caused by excessive installation torque or variations in cavity/cartridge machining. The manual override feature requires minimal force (5 lbs at 1000 psi on Port 1), facilitating ease of operation under varied pressure conditions. Designed for reliability and efficient operation across various applications, the DMDALBN211 enhances machine performance while maintaining stability and safety in hydraulic operations.

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.
