The Sun Hydraulics DMDADBV648 (DMDADBV648) 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 hydraulic system applications. It features a fatigue rating of 5000 psi (350 bar), making it suitable for high-pressure environments. The valve operates with no minimum hydraulic pressure required, enhancing its versatility across various hydraulic systems. The DMDADBV648 incorporates closed transitions between Spools B and R, optimizing performance by providing faster and more consistent response times in pilot control applications where capacity is less critical. It employs a wet armature design; the working fluid surrounds the armature which helps in heat management but requires careful selection of fluids to avoid breakdown and varnish formation that could impair functionality. For manual override operations, the valve comes equipped with a detent mechanism designed for temporary actuation with a mechanical life expectancy of approximately 7,000 cycles. Additionally, the valve supports EPDM seals for compatibility with phosphate ester fluids while remaining sensitive to petroleum-based products which can damage the seals. This model also features interchangeable coils compatible with other Sun Series 1 solenoid products, offering flexibility in maintenance and upgrades. The floating style construction minimizes internal part binding due to installation torque or cavity/cartridge machining variations. With a maximum operating pressure of 5000 psi (350 bar) and flow capacity up to 12 gpm (45 L/min), along with rapid response times typically around 50 ms, the DMDADBV648 is an efficient solution for controlling flow direction in high-pressure 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.
