The Sun Hydraulics DMDATNV736 (DMDATNV736) is a high-performance solenoid-operated 3-way, 2-position cartridge valve designed for robust and efficient hydraulic control. This direct-acting, balanced spool directional valve operates without requiring a minimum hydraulic pressure, making it highly effective in a variety of applications. The valve features a fatigue rating for up to 5000 psi (350 bar) service, ensuring durability and reliability under high-pressure conditions. Equipped with interchangeable coils compatible with other Sun Series 1 solenoid products, the DMDATNV736 offers flexible installation options with its ability to mount coils in either direction on the tube. The design incorporates Sun\u2019s floating style construction which minimizes internal parts binding due to excessive installation torque or variations in cavity/cartridge machining. This feature significantly enhances the operational life and reliability of the valve. The DMDATNV736 utilizes a wet armature design where the working fluid surrounds the armature, which is beneficial for heat dissipation but requires consideration of fluid compatibility due to potential breakdown at high temperatures. Specifically configured cartridges with EPDM seals are recommended for systems using phosphate ester fluids, avoiding exposure to petroleum-based fluids that could damage the seals. This model also offers manual override options with a detent mechanism designed for temporary actuation, supporting up to approximately 7,000 cycles mechanically. Key specifications include a maximum operating pressure of 5000 psi (350 bar), flow capacity up to 12 gpm (45 L/min), and rapid response times typically around 50 ms. Additionally, it supports switching frequencies up to 15,000 cycles/hr and allows easy maintenance with available Viton seal kits for both cartridge and coil components.

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.
