The Sun Hydraulics DMDATBN836 (DMDATBN836) 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 reliability in demanding applications. The valve features a fatigue-rated solenoid tube assembly capable of handling pressures up to 5000 psi (350 bar), ensuring durability and long-term performance under high-pressure conditions. The DMDATBN836 model incorporates closed transitions between Spools B and R, enhancing performance by providing faster and more consistent response times, particularly suitable for pilot control applications where capacity is less critical. Its wet armature design allows the working fluid to surround the armature, which is beneficial for heat dissipation but requires consideration of fluid characteristics due to potential heat-related degradation. This model is equipped with manual override options including D, L, and T controls with a mechanical life expectancy of about 7,000 cycles. It uses EPDM seals optimized for phosphate ester fluids while being incompatible with petroleum-based substances which could damage the seals. The valve supports a flow capacity of up to 12 gpm (45 L/min) and features interchangeable coils compatible with other Sun Series 1 solenoid products, enhancing flexibility and ease of maintenance. Additional technical specifications include a typical response time of 50 ms, maximum operating pressure of 5000 psi (350 bar), and switching frequency up to 15,000 cycles per hour. The design also benefits from Sun\u2019s floating style construction which minimizes internal parts binding caused by installation torque or machining variations in the cavity/cartridge setup.

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.
