The Sun Hydraulics DMDATBN299 (Material Number DMDATBN299) is a high-performance solenoid-operated 3-way, 2-position cartridge valve featuring a direct-acting, balanced spool design. This robust valve is engineered to handle a maximum operating pressure of 5000 psi (350 bar) and offers a flow capacity of up to 12 gpm (45 L/min). It boasts an impressive response time of approximately 50 ms and is capable of handling switching frequencies up to 15,000 cycles per hour. Designed for durability, the DMDATBN299 utilizes a wet armature design where the working fluid surrounds the armature, aiding in heat management during prolonged coil energization. This model is particularly suited for applications requiring precise control with minimal hydraulic pressure for operation. The valve\u2019s manual override feature provides temporary actuation with a mechanical life expectancy of around 7,000 cycles. Additionally, the construction incorporates Sun's floating style to minimize internal parts binding that can occur due to excessive installation torque or cavity-cartridge machining variations. The solenoid tube assembly of this model is rated for fatigue at high pressures and its spools (B and R) are designed to be closed during transition between positions, enhancing performance by ensuring faster and more consistent response times. This valve also features interchangeable coils compatible with other Sun Series 1 solenoid products, which can be mounted in either direction on the tube. It comes equipped with EPDM seals suitable for systems using phosphate ester fluids; however, exposure to petroleum-based fluids should be avoided as it could damage the seals. For those seeking reliable and efficient directional control in hydraulic systems, the Sun Hydraulics DMDATBN299 offers an effective solution tailored for high-pressure applications where performance and reliability are paramount.

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.
