The Sun Hydraulics DMDATRV72419 (DMDATRV72419) is a solenoid-operated, 3-way, 2-position cartridge valve designed for high-performance hydraulic systems. This direct-acting, balanced spool directional valve operates with no minimum hydraulic pressure requirement, ensuring reliable functionality across a range of applications. The valve features a fatigue-rated solenoid tube assembly capable of handling up to 5000 psi (350 bar), making it suitable for demanding operations. The model incorporates closed transitions between Spools B and R, enhancing performance by providing faster and more consistent response times when utilized as pilot controls. This design choice sacrifices capacity for increased control precision in critical applications. Additionally, the manual override options available with the D or L control are primarily intended for temporary actuation, with a mechanical life expectancy of about 7,000 cycles. For environments using phosphate ester fluids, cartridges equipped with EPDM seals are recommended to prevent damage from exposure to petroleum-based substances. The wet armature design of the valve ensures that the working fluid surrounds the armature which may require consideration regarding coil energization duration due to potential fluid breakdown from heat exposure. Interchangeability is a key feature of this model; its coils are compatible with other Sun Series 1 solenoid products and can be mounted in either direction on the tube. The construction utilizes Sun\u2019s floating style to minimize internal binding caused by excessive installation torque or cavity/cartridge machining variations. This model also supports up to 12 gpm (45 L/min) capacity and allows rapid switching frequencies up to 15,000 cycles/hour. Its robust build and versatile specifications make it an ideal choice for various hydraulic control applications requiring precise directional control and reliable operation under high pressure 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.
