The Sun Hydraulics DMDATNV236 (DMDATNV236) is a high-performance solenoid-operated 3-way, 2-position cartridge valve designed for demanding hydraulic applications. It features a direct-acting, balanced spool directional control that provides precise operation without the need for minimum hydraulic pressure. The valve boasts a robust construction with a fatigue rating of 5000 psi (350 bar), ensuring durability and reliability in high-pressure environments. Key specifications include a maximum flow capacity of 12 gpm (45 L/min) and rapid response times, typically around 50 ms. The DMDATNV236 employs EPDM seals suited for systems using phosphate ester fluids, while its wet armature design allows the working fluid to cool the armature, mitigating heat buildup during prolonged coil energization. This design consideration is crucial as certain fluids can degrade under sustained high temperatures. This model incorporates interchangeable coils with other Sun Series 1 solenoid products, enhancing flexibility and ease of maintenance. The floating style construction minimizes internal parts binding, which can occur due to excessive installation torque or cavity/cartridge machining variations. Additionally, it offers manual override capabilities with a detent mechanism designed for temporary actuation, supporting approximately 7,000 cycles mechanically. The DMDATNV236 is an ideal solution for applications requiring reliable switching and directional control of hydraulic flows with fast response times and high cyclic rates up to 15,000 cycles per hour. Its precise control and compatibility with various hydraulic fluids make it a versatile component in complex hydraulic systems.

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.
