The Sun Hydraulics DMDAMPN514 (DMDAMPN514) is a high-performance, solenoid-operated 3-way, 2-position cartridge valve. This direct-acting, balanced spool directional valve is engineered to handle a maximum operating pressure of 5000 psi (350 bar) and is fatigue rated for the same, ensuring durability and reliability in demanding applications. With a flow capacity of 12 gpm (45 L/min), it is suitable for various hydraulic systems. The DMDAMPN514 features closed spools B and R in the transition between positions, enhancing performance by ensuring faster and more consistent response times, particularly beneficial when used as pilot controls. The valve operates without requiring a minimum hydraulic pressure, which adds to its versatility in different system conditions. Additionally, the model includes manual override options with a mechanical life expectancy of approximately 7,000 cycles, useful for temporary actuation. This model is equipped with EPDM seals intended specifically for use with phosphate ester fluids; however, these seals are sensitive to petroleum-based fluids which can cause damage. The wet armature design of the valve ensures that the working fluid surrounds the armature to manage heat during operation\u2014a critical consideration if the coil remains energized over extended periods. Moreover, the DMDAMPN514 incorporates interchangeable coils compatible with other Sun Series 1 solenoid products and features Sun's floating style construction to minimize internal parts binding. This construction technique aids in accommodating excessive installation torque and variations in cavity/cartridge machining, thereby enhancing overall performance stability and reliability.

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.
