The Sun Hydraulics DMDALBN824 (DMDALBN824) is a high-performance solenoid-operated 3-way, 2-position cartridge valve. This direct-acting, balanced spool directional valve is designed for robust operation in various hydraulic systems. With a maximum operating pressure of 5000 psi (350 bar) and a flow capacity of 12 gpm (45 L/min), it suits applications requiring precise control and reliability. The valve features closed transitions between positions B and R, optimizing performance by ensuring faster and more consistent response times, particularly useful in pilot control setups where flow capacity is less critical. The DMDALBN824 incorporates a fatigue-rated solenoid tube assembly suitable for demanding environments. It is equipped with EPDM seals specifically for use with phosphate ester fluids, cautioning against the use of petroleum-based fluids which can degrade these seals. The wet armature design of the valve helps in cooling but requires consideration regarding the type of fluid used due to potential breakdowns under prolonged exposure to heat. This model supports interchangeable coils with other Sun Series 1 solenoid products and offers flexibility in mounting direction on the tube. It also features Sun's floating style construction which minimizes internal parts binding \u2014 a common issue arising from excessive installation torque or cavity/cartridge machining variations. For manual override operations, the DMDALBN824 includes a detent mechanism designed for temporary actuation with an estimated mechanical life expectancy of around 7,000 cycles. Its design considerations also encompass ease of maintenance and long-term durability, making it an ideal choice for sophisticated hydraulic applications that demand high switching frequencies (up to 15,000 cycles/hr) and quick response times (typical 50 ms).

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.
