The Sun Hydraulics DMDATRV848 (DMDATRV848) is a high-performance, solenoid-operated 3-way, 2-position cartridge valve designed for precise hydraulic control. This direct-acting, balanced spool directional valve operates with no minimum hydraulic pressure required, ensuring reliable functionality across a range of applications. With a maximum operating pressure of 5000 psi (350 bar) and a flow capacity of up to 12 gpm (45 L/min), it is well-suited for demanding environments. The DMDATRV848 features closed transitions between spool positions B and R, optimizing performance by providing faster and more consistent response times ideal for pilot control applications where capacity is less critical. Its manual override option includes a detent mechanism designed for temporary actuation with an expected mechanical life of approximately 7,000 cycles. The valve's wet armature design helps in cooling but requires consideration regarding the type of fluid used; EPDM seals in the valve are specifically intended for systems using phosphate ester fluids and should not be exposed to petroleum-based substances. Additionally, this model incorporates Sun's floating style construction which minimizes internal parts binding that could result from excessive installation torque or variations in cavity/cartridge machining. The interchangeable coils compatible with other Sun Series 1 solenoid products add to its versatility, making it an adaptable choice for various hydraulic systems. With its robust build and efficient design, the DMDATRV848 enhances system reliability while maintaining tight control over fluid direction and flow.

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.
