The Sun Hydraulics DMDAMRV (DMDAMRV) is a high-performance solenoid-operated 3-way, 2-position cartridge valve designed for demanding hydraulic applications. It features a direct-acting, balanced spool that ensures reliable control of hydraulic flow with a maximum operating pressure of 5000 psi (350 bar) and a flow capacity of up to 12 gpm (45 L/min). The valve's solenoid tube assembly is fatigue rated, making it suitable for rigorous service conditions. This model incorporates closed transitions between spool positions B and R, enhancing performance by providing faster and more consistent response times, particularly useful in pilot control applications where capacity is less critical. The DMDAMRV operates without requiring a minimum hydraulic pressure, adding to its versatility in various system configurations. For systems using phosphate ester fluids, cartridges equipped with EPDM seals are recommended to prevent damage from petroleum-based substances. The wet armature design of the valve helps in heat management but requires consideration regarding the type of fluid used due to potential breakdown and varnish formation at elevated temperatures. The valve also features interchangeable coils compatible with other Sun Series 1 solenoid products and can be installed in either orientation on the tube. Additionally, it employs Sun's floating style construction which minimizes internal parts binding\u2014a common issue caused by excessive installation torque or variations in cavity/cartridge machining. Designed for ease of manual operation when necessary, the DMDAMRV includes a manual override mechanism with a detent feature for temporary actuation. Its robust construction promises a mechanical life expectancy of approximately 7,000 cycles for models equipped with manual controls D, L, or T. This makes it an ideal choice for applications requiring both automatic and occasional manual control without compromising operational integrity.

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.
