The Sun Hydraulics DMDAMRN524 (DMDAMRN524) is a high-performance, solenoid-operated 3-way, 2-position cartridge valve. This direct-acting, balanced spool directional valve is designed for robust and efficient performance with a maximum operating pressure of 5000 psi (350 bar) and a flow capacity of up to 12 gpm (45 L/min). The DMDAMRN524 features closed transitions between spool positions B and R, enhancing performance by ensuring faster and more consistent response times, particularly suitable for applications requiring precise control such as pilot operations. Equipped with a fatigue-rated solenoid tube assembly, the valve is built to handle demanding service conditions. The manual override feature included in models with D or L control is intended for temporary actuation, supported by a mechanical life expectancy of approximately 7,000 cycles. Additionally, the valve incorporates EPDM seals configured specifically for use with phosphate ester fluids; however, these seals are susceptible to damage when exposed to petroleum-based substances. This model benefits from Sun Hydraulics' floating style construction which minimizes internal part binding due to installation torque or machining variations in the cavity/cartridge. The wet armature design of the solenoid ensures that the working fluid surrounds the armature which may be relevant when considering fluid types and operational temperatures. Interchangeability of coils within Sun Series 1 solenoid products adds versatility in maintenance and replacement tasks. Overall, the DMDAMRN524 offers reliable operation with no minimum hydraulic pressure required for activation, making it an adaptable solution for various hydraulic control systems needing precise directional control and rapid response times.

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.
