The Sun Hydraulics DMDADAN736 (DMDADAN736) is a high-performance solenoid-operated 3-way, 2-position cartridge valve designed for precise hydraulic control. This direct-acting, balanced spool directional valve is engineered to operate efficiently with no minimum hydraulic pressure requirement, making it versatile for various applications. The valve features a fatigue rating for up to 5000 psi (350 bar) service, ensuring durability and reliability in demanding environments. The DMDADAN736 incorporates closed transitions between Spools B and R, enhancing performance limits while sacrificing some capacity\u2014ideal for pilot controls where capacity is less critical but fast and consistent response times are necessary. It also includes manual override options with the D or L control featuring a detent mechanism designed for temporary actuation. The mechanical life expectancy of these manual controls is approximately 7,000 cycles. For compatibility with different fluid types, cartridges configured with EPDM seals are specified for systems using phosphate ester fluids; however, they should not be exposed to petroleum-based fluids which can damage the seals. The wet armature design of the valve allows the working fluid to surround the armature, which could be a consideration if the coil remains energized over extended periods due to potential breakdowns in certain fluids like water-glycol mixtures. Furthermore, this model boasts interchangeable coils compatible with other Sun Series 1 solenoid products and features Sun\u2019s floating style construction that minimizes internal parts binding caused by excessive installation torque or variations in cavity/cartridge machining. With a maximum operating pressure of 5000 psi and a flow capacity of up to 12 gpm (45 L/min), the DMDADAN736 provides robust performance for advanced hydraulic systems requiring precise direction control.

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.
