The Sun Hydraulics DMDADNV736 (DMDADNV736) is a high-performance solenoid-operated 3-way, 2-position cartridge valve designed for precise control in hydraulic systems. This direct-acting, balanced spool directional valve is notable for its robust construction and operational efficiency, featuring a solenoid tube assembly that is fatigue rated for 5000 psi (350 bar) service. The valve operates without the need for minimum hydraulic pressure, enhancing its versatility across various applications. The model DMDADNV736 incorporates closed transitions between spool positions B and R, optimizing performance by providing faster and more consistent response times, especially useful in pilot control applications where capacity is less critical. Additionally, the wet armature design of the valve ensures that the working fluid surrounds the armature, which may require consideration regarding fluid type due to potential heat exposure during prolonged coil energization. This valve is compatible with EPDM seals specifically for use with phosphate ester fluids; however, these seals must avoid exposure to petroleum-based fluids to prevent damage. For maintenance and longevity, the manual override feature included in models with D or L control uses a detent mechanism intended only for temporary actuation, supporting approximately 7,000 cycles. Furthermore, this model maintains interchangeability with other Sun Series 1 solenoid products concerning coils which can be mounted in either direction on the tube. It also benefits from Sun's floating style construction that minimizes internal parts binding caused by excessive installation torque or variations in cavity/cartridge machining. With a maximum operating capacity of 12 gpm (45 L/min) and rapid typical response time of 50 ms, the DMDADNV736 offers a reliable solution for dynamic hydraulic system requirements while ensuring minimal leakage and high switching frequency capabilities.

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.
