The Sun Hydraulics DMDAMRN612 (DMDAMRN612) is a solenoid-operated 3-way, 2-position cartridge valve that serves as a direct-acting, balanced spool directional valve. Designed for robust industrial applications, this valve features a fatigue rating suitable for services up to 5000 psi (350 bar). The DMDAMRN612 is engineered with closed transitions between Spools B and R, optimizing performance by providing faster and more consistent response times, especially useful in pilot control applications where capacity is less critical. This model operates without requiring a minimum hydraulic pressure, enhancing its versatility across various hydraulic systems. It includes manual override options with the D or L control featuring a detent mechanism intended for temporary actuation. The mechanical life expectancy of the manual control assembly in this model is approximately 7,000 cycles. The valve's wet armature design indicates that the working fluid directly contacts the armature, which could influence fluid integrity if exposed to prolonged heat from the coil. The DMDAMRN612 incorporates EPDM seals suited for systems utilizing phosphate ester fluids while being incompatible with petroleum-based fluids which could damage these seals. Additionally, it maintains compatibility with other Sun Series 1 solenoid products regarding interchangeable coils that can be mounted in either direction on the tube. This model also benefits from Sun's floating style construction which helps prevent internal parts binding due to variations in installation torque or cavity/cartridge machining. Key specifications include a maximum flow capacity of 12 gpm (45 L/min), typical response times of 50 ms, and maximum leakage at 5 in\u00b3/min at 3000 psi. It supports up to 15,000 switching cycles per hour and requires manual override force of about 5 lbs at 1000 psi for Port 1 operation. The compact design measures a solenoid tube diameter of .75 inches (19 mm) and weighs approximately .60 lb (0.30 kg), ensuring it can be integrated into various setups without significant spatial constraints.

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.
