The Sun Hydraulics DMDADRV524 (DMDADRV524) 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 for 5000 psi (350 bar) service, ensuring reliable operation under high-pressure conditions. The valve's spools B and R are closed during the transition between positions, which enhances performance by providing faster and more consistent response times, ideal for applications requiring precise control such as pilot operations where capacity is less critical. The DMDADRV524 operates without requiring a minimum hydraulic pressure, adding to its versatility across various hydraulic systems. It includes options for manual overrides with D, L, or T controls; however, these are intended for temporary actuation with a mechanical life expectancy of around 7,000 cycles. It is essential to note that cartridges equipped with EPDM seals should only be used with phosphate ester fluids as exposure to petroleum-based fluids can damage the seals. This model incorporates Sun Hydraulics\u2019 floating style construction which minimizes internal parts binding due to installation torque variations or cavity/cartridge machining discrepancies. Additionally, the wet armature design of the solenoid means the working fluid surrounds the armature which can affect fluid integrity over extended periods of energization. The interchangeable coils compatible with other Sun Series 1 solenoid products offer further flexibility and ease of maintenance. With a maximum operating pressure of 5000 psi and a flow capacity up to 12 gpm (45 L/min), along with fast response times typically around 50 ms and maximum leakage at stringent levels, this valve is well-suited for high-demand applications seeking precision and durability in hydraulic control 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.
