The Sun Hydraulics DMDATRV648 (DMDATRV648) is a solenoid-operated 3-way, 2-position cartridge valve designed for high-performance hydraulic systems. This direct-acting, balanced spool directional valve has a robust construction that includes a fatigue-rated solenoid tube assembly capable of handling pressures up to 5000 psi (350 bar). The valve features closed transitions between Spools B and R, enhancing performance by ensuring faster and more consistent response times, particularly suitable for applications where capacity is less critical. The DMDATRV648 operates without requiring a minimum hydraulic pressure, making it highly effective in various operating environments. It includes options for manual override through the D or L control, with a detent mechanism designed for temporary actuation. The mechanical life expectancy of the manual control assembly is approximately 7,000 cycles. Additionally, this model incorporates EPDM seals specifically for use with phosphate ester fluids; however, these seals are not compatible with petroleum-based fluids which can cause damage. This model's wet armature design allows the working fluid to surround the armature, which helps in heat management but requires consideration regarding fluid selection as some may degrade under prolonged exposure to heat. The interchangeable coils are compatible with other Sun Series 1 solenoid products and can be mounted in either direction to suit different installation requirements. Key specifications include a flow capacity of 12 gpm (45 L/min), typical response times of 50 ms, and maximum operating pressures up to 5000 psi (350 bar). The valve also features Sun's floating style construction which minimizes internal parts binding due to installation torque or cavity/cartridge machining variations. This makes the DMDATRV648 an adaptable solution for advanced hydraulic systems requiring reliable directional control and fast response times.

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.
