The Sun Hydraulics DMDALAN71219 (DMDALAN71219) is a solenoid-operated 3-way, 2-position cartridge valve designed for precise hydraulic control. This direct-acting, balanced spool directional valve integrates seamlessly into various hydraulic systems without the need for minimum hydraulic pressure to operate. With a robust design that features a fatigue rating of 5000 psi (350 bar), the valve ensures reliable performance in demanding applications. The DMDALAN71219 model boasts several key features enhancing its functionality and durability. It includes spools B and R, which are closed during the transition between two positions to provide faster and more consistent response times, making it ideal for pilot control applications where capacity is not the primary concern. Additionally, models equipped with D or L manual controls include a detent mechanism in the manual override intended for temporary actuation with a mechanical life expectancy of approximately 7,000 cycles. This valve is compatible with EPDM seals specifically configured for use with phosphate ester fluids; however, exposure to petroleum-based fluids should be avoided as it can damage the seals. The wet armature design of the valve allows the working fluid to surround the armature, mitigating heat buildup from prolonged coil energization\u2014a crucial feature for maintaining fluid integrity and preventing varnish formation that could impair cartridge function. Interchangeability of coils with other Sun Series 1 solenoid products adds versatility to this unit, allowing easy maintenance and replacement. The floating style construction incorporated into this model minimizes internal parts binding caused by excessive installation torque or machining variations in cavity/cartridge setups. With specifications like a maximum operating pressure of 5000 psi (350 bar), flow capacity up to 12 gpm (45 L/min), and rapid response times typically around 50 ms, the Sun Hydraulics DMDALAN71219 is tailored for efficient and reliable operation in complex hydraulic 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.
