The Sun Hydraulics DMDATRV214 (DMDATRV214) is a solenoid-operated 3-way, 2-position cartridge valve designed for high-performance hydraulic systems. This direct-acting, balanced spool directional valve operates without the need for minimum hydraulic pressure, enhancing its versatility in various applications. It features a robust design with a fatigue rating of 5000 psi (350 bar), making it suitable for demanding environments. The DMDATRV214 valve is specifically engineered to provide reliable operation with fast and consistent response times, particularly beneficial when used as pilot controls. Its closed transition between positions (Spools B and R) ensures higher performance limits, although at a reduced capacity which is not typically an issue in pilot control applications. This model incorporates a wet armature design where the working fluid surrounds the armature; this can affect fluid characteristics if the coil remains energized for extended periods. The valve's compatibility with EPDM seals makes it suitable for use with phosphate ester fluids, while exposure to petroleum-based fluids should be avoided to prevent seal damage. Additionally, the DMDATRV214 offers interchangeable coils with other Sun Series 1 solenoid products and features Sun's floating style construction to minimize internal parts binding. This construction also aids in accommodating variations in cavity/cartridge machining and installation torque, enhancing the overall reliability and ease of use. With specifications like a maximum operating pressure of 5000 psi, capacity up to 12 gpm (45 L/min), and rapid response times around 50 ms typical, this valve is an excellent choice for high-efficiency hydraulic systems requiring precise control. Its manual override options provide temporary actuation facilitated by a detent mechanism designed for up to approximately 7,000 cycles, ensuring long-term operational stability and performance.

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.
