The Sun Hydraulics DMDATRV214N (DMDATRV214N) is a high-performance solenoid-operated 3-way, 2-position cartridge valve that features a direct-acting, balanced spool design. This model is specifically engineered to operate without minimum hydraulic pressure, making it highly effective for various applications requiring reliable directional control of fluid flow. The valve offers a maximum operating pressure of 5000 psi (350 bar) and a flow capacity of up to 12 gpm (45 L/min), suitable for robust hydraulic systems. The DMDATRV214N incorporates advanced design features such as closed transitions between spool positions, which enhance performance by providing faster and more consistent response times, especially beneficial in pilot control applications where capacity is less critical. It also includes a manual override with a detent mechanism designed for temporary actuation, supporting approximately 7,000 cycles. This model uses EPDM seals configured for compatibility with phosphate ester fluids; however, exposure to petroleum-based fluids should be avoided as it can damage the seals. The wet armature design utilized in this valve allows the working fluid to surround the armature, helping in heat management but requires consideration of fluid characteristics under prolonged energization. Interchangeability of coils with other Sun Series 1 solenoid products adds versatility, allowing for easier maintenance and replacement processes. Additionally, the valve's construction minimizes internal parts binding through its floating style construction\u2014a key feature for ensuring reliability despite installation torque variations or cavity/cartridge machining discrepancies. With these capabilities and specifications, the Sun Hydraulics DMDATRV214N valve stands out as a robust solution for directional control in sophisticated 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.
