The Sun Hydraulics DMDALAV524 (DMDALAV524) is a high-performance solenoid-operated 3-way, 2-position cartridge valve. This direct-acting, balanced spool directional valve is designed to operate seamlessly without the need for minimum hydraulic pressure. Featuring a fatigue rating for 5000 psi (350 bar) service, it ensures robust performance in demanding applications. The valve's construction includes a wet armature design where the working fluid surrounds the armature, which can affect fluid properties if the coil remains energized over extended periods. With a capacity of 12 gpm (45 L/min) and maximum operating pressure of 5000 psi (350 bar), this valve is capable of handling significant hydraulic flow rates efficiently. The response time is notably quick at approximately 50 ms, and it supports a switching frequency of up to 15000 cycles per hour, making it suitable for applications requiring frequent actuation. The manual override feature requires a force of about 5 lbs at 1000 psi for port activation and has a stroke length of .10 inches (2.5 mm). This model incorporates Sun\u2019s floating style construction that minimizes internal parts binding, which can occur due to excessive installation torque or variations in cavity/cartridge machining. Additionally, the spools B and R maintain closed positions during transitions between states to enhance performance limits at the cost of lower capacity\u2014ideal for pilot control applications where rapid and consistent response times are critical. The DMDALAV524 is equipped with interchangeable coils compatible with other Sun Series 1 solenoid products, allowing for flexible use and easy maintenance. Seals configured with EPDM are specifically designed for systems using phosphate ester fluids; however, they should not be exposed to petroleum-based fluids as this can cause seal damage. This model also features a manual override detent mechanism intended for temporary actuation only, highlighting its suitability for precise control tasks in various 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.
