The Sun Hydraulics DMDADRN536 (DMDADRN536) is a high-performance solenoid-operated 3-way, 2-position cartridge valve designed for robust hydraulic system applications. This direct-acting, balanced spool directional valve operates efficiently without the need for minimum hydraulic pressure, ensuring reliable functionality across various operational conditions. It features a fatigue-rated solenoid tube assembly capable of handling up to 5000 psi (350 bar), making it suitable for high-pressure applications. The DMDADRN536 valve boasts a quick and consistent response time due to its closed transition between positions, which is particularly advantageous when used as pilot controls. The manual override incorporated in this model has a mechanical life expectancy of approximately 7,000 cycles and includes detent mechanisms in the D or L control for temporary actuation. The wet armature design utilized in this valve means that the working fluid surrounds the armature, which could be vital when considering fluid compatibility and coil energization duration. This model is compatible with EPDM seals intended specifically for systems using phosphate ester fluids; however, these seals are susceptible to damage from exposure to petroleum-based fluids. The DMDADRN536 also supports interchangeable coils with other Sun Series 1 solenoid products and can be mounted on the tube in either direction to accommodate different installation requirements. Additional specifications include a maximum flow capacity of 12 gpm (45 L/min), typical response times of 50 ms, and maximum operating pressures up to 5000 psi (350 bar). The design incorporates Sun's floating style construction which minimizes internal parts binding\u2014a common issue caused by excessive installation torque or cavity/cartridge machining variations. This makes the DMDADRN536 an adaptable solution for demanding hydraulic systems seeking precise control and long-term reliability.

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.
