The Sun Hydraulics DMDAMRN736 (DMDAMRN736) is a high-performance, solenoid-operated 3-way, 2-position cartridge valve designed for use in various hydraulic systems. This direct-acting, balanced spool directional valve is notable for its robust construction and operational efficiency. The DMDAMRN736 features spools B and R which are closed during the transition between positions, enhancing performance limits at the cost of lower capacity. This characteristic makes it particularly suitable for pilot control applications where rapid and consistent response times are crucial. With a maximum operating pressure of 5000 psi (350 bar) and a flow capacity of up to 12 gpm (45 L/min), this valve is engineered to handle demanding tasks efficiently. Its solenoid tube assembly is fatigue rated for high-pressure service, ensuring durability and reliability under rigorous conditions. Additionally, the valve incorporates Sun's floating style construction which minimizes internal parts binding due to installation torque or cavity/cartridge machining variations. The DMDAMRN736 can be equipped with EPDM seals suitable for systems using phosphate ester fluids, though these seals must not be exposed to petroleum-based fluids as they could be damaged. The wet armature design allows the working fluid to surround the armature, potentially affecting fluid integrity if exposed to prolonged heat from an energized coil. This model also features interchangeable coils with other Sun Series 1 solenoid products and offers manual override options with a mechanical life expectancy of approximately 7,000 cycles. These characteristics make the DMDAMRN736 an adaptable solution for various hydraulic system applications requiring reliable directional control and swift response times.

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.
