The Sun Hydraulics DMDATRN299 (DMDATRN299) is a high-performance solenoid-operated 3-way, 2-position cartridge valve that ensures efficient directional control in hydraulic systems. This direct-acting, balanced spool valve is designed to operate seamlessly without the need for a minimum hydraulic pressure, enhancing its versatility across various applications. It features a robust solenoid tube assembly that is fatigue rated for up to 5000 psi (350 bar), making it suitable for high-pressure environments. The DMDATRN299 valve offers exceptional performance characteristics, including closed spools B and R during transitions between positions to optimize performance limits at the cost of lower capacity. However, this attribute is particularly beneficial in pilot control applications where capacity is less critical but fast and consistent response times are crucial. The valve's response time is typically around 50 ms, and it supports a maximum operating pressure of 5000 psi (350 bar) with a flow capacity of up to 12 gpm (45 L/min). Additionally, the model incorporates Sun\u2019s floating style construction which minimizes internal part binding due to excessive installation torque or cavity/cartridge machining variations. It also features interchangeable coils with other Sun Series 1 solenoid products and can be mounted on the tube in either direction for added installation flexibility. For systems using phosphate ester fluids, cartridges configured with EPDM seals are recommended as exposure to petroleum-based fluids can damage these seals. The manual override option in models equipped with D or L control utilizes a detent mechanism intended for temporary actuation only, supporting about 7,000 cycles mechanically. This valve\u2019s design includes a wet armature setup where the working fluid surrounds the armature which may be sensitive to prolonged energization leading to fluid breakdown in certain conditions. Overall, the Sun Hydraulics DMDATRN299 offers reliable performance for specialized hydraulic applications requiring precise control and rapid response under varying operational conditions.

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.
