The Sun Hydraulics DMDAMRN214N (DMDAMRN214N) is a high-performance solenoid-operated 3-way, 2-position cartridge valve. This direct-acting, balanced spool directional valve is designed for robust and efficient hydraulic flow control within a variety of applications. With its fatigue rating for 5000 psi (350 bar) service, the DMDAMRN214N ensures reliable operation under demanding conditions. The valve features closed transitions between Spools B and R, optimizing performance by providing faster and more consistent response times, particularly suitable for pilot control applications where capacity is less critical. This model is direct actuated and operates without requiring a minimum hydraulic pressure, enhancing its versatility across different hydraulic systems. It includes options for manual override controls (D, L, T), which are primarily intended for temporary actuation with a mechanical life expectancy of around 7,000 cycles. The DMDAMRN214N utilizes EPDM seals suitable for phosphate ester fluids; however, these seals must not be exposed to petroleum-based fluids as they could be damaged. Further enhancing its utility, the valve features a wet armature design allowing the working fluid to cool the armature\u2014important to consider if the coil remains energized over extended periods. The model supports interchangeable coils with other Sun Series 1 solenoid products and can be mounted in either direction on the tube. Additionally, it incorporates Sun's floating style construction which minimizes internal parts binding due to installation torque or machining variations of cavity/cartridge. With specifications like a flow capacity of 12 gpm (45 L/min), maximum operating pressure of 5000 psi (350 bar), and typical response time of 50 ms, this valve is engineered to meet rigorous industrial standards while providing precise control over hydraulic flow in complex 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.
