The Sun Hydraulics DMDALBN924 (DMDALBN924) is a high-performance, solenoid-operated 3-way, 2-position cartridge valve, designed for direct-acting operation with a balanced spool directional control mechanism. It features a robust design with a fatigue rating of up to 5000 psi (350 bar), making it suitable for demanding hydraulic applications. The valve offers precise control with closed transitions between spool positions B and R, enhancing performance by ensuring faster and more consistent response times, particularly beneficial in pilot control setups where capacity is less critical. This model incorporates a wet armature design where the working fluid surrounds the armature. This setup is essential in applications where the coil may be energized for extended periods, although care must be taken with fluid selection as some may degrade under prolonged heat exposure. The valve's manual override feature is designed for temporary actuation, supported by a detent mechanism that sustains approximately 7,000 cycles. For compatibility with various hydraulic systems, cartridges configured with EPDM seals are specifically intended for use with phosphate ester fluids; however, they should not be exposed to petroleum-based fluids which can deteriorate the seals. The model maintains interchangeability within Sun's Series 1 solenoid products concerning coils which can be mounted in either direction to accommodate different system configurations. Key specifications include a maximum flow capacity of 12 gpm (45 L/min), a typical response time of 50 ms, and maximum operational pressure of 5000 psi (350 bar). Additionally, it features Sun\u2019s floating style construction that minimizes internal binding due to installation or component variances. This makes the DMDALBN924 an ideal choice for various high-pressure applications requiring reliable and efficient directional control 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.
