The Sun Hydraulics DMDATBN514 (DMDATBN514) is a high-performance solenoid-operated 3-way, 2-position cartridge valve designed for precise hydraulic control. The valve features a direct-acting, balanced spool with closed transitions between positions B and R, enhancing performance by ensuring faster and more consistent response times, particularly suitable for pilot control applications where capacity is less critical. This model operates without requiring a minimum hydraulic pressure, making it versatile in various system conditions. Constructed to handle a maximum operating pressure of 5000 psi (350 bar) and a flow capacity of up to 12 gpm (45 L/min), the DMDATBN514 is built to withstand demanding operational conditions. It includes an innovative wet armature design wherein the working fluid surrounds the armature, crucial for managing heat during prolonged coil energization. However, users should note that certain fluids like water-glycol mixtures may degrade under high temperatures. This valve model also benefits from Sun Hydraulics' floating style construction which minimizes internal part binding due to installation torque or cavity/cartridge machining variations. The manual override feature in models equipped with D or L control is designed for temporary actuation with a mechanical life expectancy of approximately 7,000 cycles. Moreover, the DMDATBN514 accommodates interchangeable coils from other Sun Series 1 solenoid products and can be mounted in either direction on the tube. It is essential to use cartridges configured with EPDM seals exclusively in systems utilizing phosphate ester fluids as exposure to petroleum-based fluids can damage these seals. In summary, the Sun Hydraulics DMDATBN514 offers robust performance and flexibility for specialized hydraulic applications requiring precise directional control and rapid response under varying pressure conditions without the need for minimum hydraulic pressure.

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.
