The Sun Hydraulics DMDATRN514 (DMDATRN514) 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 uniquely constructed to handle a maximum operating pressure of 5000 psi (350 bar), making it suitable for rigorous applications. With a typical response time of 50 ms and capable of switching frequencies up to 15,000 cycles per hour, this valve ensures quick and reliable operation. The DMDATRN514 features a wet armature design which allows the working fluid to surround the armature, aiding in heat dissipation during prolonged energization periods. However, it's important to note that certain fluids like water-glycol mixtures might degrade at higher temperatures, potentially affecting valve performance. The valve's manual override option is equipped with a detent mechanism designed for temporary actuation and boasts a mechanical life expectancy of about 7,000 cycles. This model uses EPDM seals specifically for compatibility with phosphate ester fluids; exposure to petroleum-based fluids should be avoided as it can damage the seals. Additionally, the interchangeable coils from Sun\u2019s Series 1 solenoid products enhance this model\u2019s versatility and maintenance ease. The construction incorporates Sun\u2019s floating style design which minimizes internal parts binding due to installation torque or machining variations. With a flow capacity of 12 gpm (45 L/min) and minimal leakage at high pressures (5 in\u00b3/min at 3000 psi), the DMDATRN514 is engineered for both efficiency and reliability in controlling fluid direction within hydraulic circuits. This makes it an ideal choice for applications requiring precise control with robust performance characteristics.

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.
