The Sun Hydraulics DMDAXPV714 (DMDAXPV714) is a high-performance, solenoid-operated 3-way, 2-position cartridge valve designed for precise control in hydraulic systems. This direct-acting, balanced spool directional valve is engineered to operate without minimum hydraulic pressure and features a fatigue rating of 5000 psi (350 bar), making it suitable for rigorous applications. The valve's spools, B and R, are closed during the transition between positions to enhance performance by ensuring faster and more consistent response times, particularly useful in pilot control setups where capacity is less critical. Equipped with EPDM seals, the DMDAXPV714 is specifically configured for use with phosphate ester fluids; however, it must be noted that exposure to petroleum-based fluids can damage these seals. The design incorporates a wet armature setup where the working fluid surrounds the armature; this is an important consideration as prolonged energization can lead to fluid degradation at elevated temperatures. This model also boasts interchangeable coils with other Sun Series 1 solenoid products and offers flexibility in mounting direction on the tube. It features Sun\u2019s floating style construction which minimizes internal parts binding caused by excessive installation torque or cavity/cartridge machining variations. With a maximum flow capacity of 12 gpm (45 L/min) and rapid response time typically around 50 ms, it ensures efficient operation. The manual override feature has a mechanical life expectancy of about 7,000 cycles and requires minimal force for activation. This versatile valve finds its application in various hydraulic systems requiring reliable switching operations and precise control, underscored by its robust construction and thoughtful engineering enhancements designed to optimize performance and durability across demanding operational conditions.

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.
