The Sun Hydraulics DMDAMRV524 (DMDAMRV524) is a high-performance, solenoid-operated 3-way, 2-position cartridge valve that offers precise control in hydraulic systems. Designed with a balanced spool and capable of handling a maximum operating pressure of 5000 psi (350 bar), this valve is particularly suited for applications requiring robust performance under high-pressure conditions. The valve features closed transitions between spool positions B and R, enhancing performance by ensuring faster and more consistent response times during operation. This model is direct-actuated, meaning it operates without the need for minimum hydraulic pressure, allowing for flexible installation in various system configurations. It includes manual override options with a detent mechanism designed for temporary actuation, supporting up to approximately 7,000 cycles. The DMDAMRV524 also incorporates EPDM seals suitable for use with phosphate ester fluids, although these seals must avoid exposure to petroleum-based substances which can cause damage. Another key feature of the DMDAMRV524 is its wet armature design; the working fluid surrounds the armature which is beneficial for heat dissipation but requires consideration regarding fluid selection to prevent breakdown or varnish formation. The interchangeable coils with other Sun Series 1 solenoid products add to its versatility, and it utilizes Sun\u2019s floating style construction to minimize internal binding risks due to installation torque or machining variations. With additional specifications like a flow capacity of 12 gpm (45 L/min) and rapid response times typically around 50 ms, this valve ensures efficient operation and reliability in demanding hydraulic applications. Its robust design and operational features make it an excellent choice for systems where precision and durability are critical.

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.
