The Sun Hydraulics DMDAXPV71219 (DMDAXPV71219) is a high-performance, solenoid-operated 3-way, 2-position cartridge valve. This direct-acting, balanced spool directional valve is specifically designed for robust and efficient performance in various hydraulic applications. It features a fatigue rating for 5000 psi (350 bar) service, ensuring durability and reliability under high-pressure conditions. This model boasts several key features that enhance its functionality and user experience. The spools B and R are closed during the transition between their two positions, optimizing performance by providing faster and more consistent response times especially when used as pilot controls. The valve operates without requiring a minimum hydraulic pressure, adding to its versatility across different hydraulic systems. Equipped with EPDM seals, the DMDAXPV71219 is suitable for use with phosphate ester fluids, though it should not be exposed to petroleum-based fluids which can damage the seals. Its wet armature design allows the working fluid to surround the armature; however, prolonged energization of the coil should be monitored as it could lead to breakdown in certain fluid types. The manual override feature includes a detent mechanism designed for temporary actuation with a mechanical life expectancy of about 7,000 cycles. Additionally, coils used in this model are interchangeable with other Sun Series 1 solenoid products and can be mounted in either direction on the tube. Incorporating Sun\u2019s floating style construction minimizes internal parts binding due to excessive installation torque or cavity/cartridge machining variations. With a maximum operating pressure of 5000 psi (350 bar), capacity up to 12 gpm (45 L/min), and quick typical response time of 50 ms, this valve is an excellent choice for demanding applications requiring precise control 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.
