The Sun Hydraulics DMDATBN224 (DMDATBN224) is a high-performance solenoid-operated 3-way, 2-position cartridge valve that features a direct-acting, balanced spool directional design. This model is specifically engineered for robust and precise control in hydraulic systems, offering a maximum operating pressure of 5000 psi (350 bar) and a flow capacity of up to 12 gpm (45 L/min). The valve's quick response time, typically around 50 ms, ensures efficient operation in dynamic system conditions. One of the standout features of the DMDATBN224 is its closed transition between Spools B and R, which minimizes internal leakage to an impressive maximum of 5 in\u00b3/min at 3000 psi (80 cc/min at 210 bar). This characteristic enhances performance by providing faster and more consistent response times, particularly suitable for applications requiring precise pilot control where capacity is less critical. Additionally, the valve supports a switching frequency up to 15,000 cycles per hour. The construction incorporates Sun's floating style design which helps prevent binding of internal parts due to variations in installation torque or machining discrepancies. Furthermore, the valve includes manual override options with a detent mechanism designed for temporary actuation. It has been built to last with a mechanical life expectancy of around 7,000 cycles for models equipped with manual controls. For environmental compatibility, cartridges configured with EPDM seals are tailored for use with phosphate ester fluids; however, they should not be exposed to petroleum-based fluids which can damage the seals. The interchangeable coils compatible with other Sun Series 1 solenoid products add versatility and ease of maintenance. This valve's robust build and advanced engineering make it an ideal choice for demanding applications requiring reliable directional control and fast response times in 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.
