The Sun Hydraulics DMDADRN636 (DMDADRN636) is a high-performance, solenoid-operated 3-way, 2-position cartridge valve. Designed for direct-acting operation, this balanced spool directional valve does not require a minimum hydraulic pressure to function effectively. It features a fatigue-rated solenoid tube assembly for up to 5000 psi (350 bar) service, ensuring durability and reliability in demanding applications. The valve's spools (B and R) are closed during the transition between positions, enhancing performance limits while reducing capacity, which is ideal for pilot control applications where rapid and consistent response times are critical. This model incorporates a wet armature design where the working fluid surrounds the armature. This setup requires careful consideration of fluid types as heat from prolonged coil energization can degrade certain fluids like water-glycol mixtures. The DMDADRN636 is compatible with EPDM seals specifically for use with phosphate ester fluids; however, exposure to petroleum-based fluids can damage these seals. Interchangeable coils from Sun Series 1 solenoid products can be mounted on this model in either direction, adding versatility to the installation process. Additionally, it features Sun's floating style construction which minimizes internal parts binding that could occur due to excessive installation torque or variations in cavity/cartridge machining. With a maximum operating pressure of 5000 psi and a flow capacity of 12 gpm (45 L/min), the DMDADRN636 offers robust performance for various hydraulic systems. It also supports a switching frequency of up to 15000 cycles/hr and has a typical response time of 50 ms. The manual override mechanism included in models equipped with D or L control is designed for temporary actuation with an expected mechanical life of around 7,000 cycles. This makes the valve suitable for applications requiring reliable changeover under manual control without permanent adjustments.

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.
